Zabbix macro expression Do you think that would work ? (object/array) Host macros to create. " Today I am going to talk about context macro support inside Zabbix. VALUE} macro, which returns the current trigger status as an integer (0 – ok, 1 – problem) and can be used directly in trigger expressions. Zabbix supports the following macros: {MACRO} - built-in macro (see full list) {<macro>. in[eth0,bytes],5m)>100K. IP1}, {HOST. NAME1} ({HOST. In the Host name field, enter a host name (for example, "VMware VMs"). NAME}. google full of GLOBAL EXPRESSION exclusion example. 0). As an example, the following trigger checks if the trap severity item is higher than 4, and the event name should use the trap title item. Les macros {HOST. Object references: Global macro; Host macro; Available methods: usermacro. 2 Permissions. The syntax in EXPRESSION is the same as in trigger expressions (see usage limitations below). I would assume it also applies to non contextual user macros based on your experience. 4. Ex: macro1, macro2, macro3, etc. \0 returns the matched text. Substring extraction by a regular expression match (case sensitive). This is how an expression to analyze minimum received traffic value over the last five minutes and alert if the value is over 100K would look like now: min(/Zabbix server/net. Type of macro. The expressions used in triggers are very flexible. VALUE<1-9>} and {TRIGGER. Dear Friends I need to create a lot of macro . due to DHCP) to a different host. Note: To configure multiple items, create a dashboard widget field object for each item with an incremented number in the property name. For example, one macro value can be reused in an unlimited number of triggers. This macro is defined in the template, and is used successfully in an item in the template for hosts using that template. IFNAME. Use of host-level macro in the Double-quoting the parameter is not necessary as Zabbix will take care of any ambiguous special symbols, if present in the resolved macro. Parameters: pattern - the regular expression to match;; output - the output options. 8. 4, when low-level discovery macros are used in JSONPath preprocessing and their values are resolved, the following rules of escaping special characters are applied: When used in the expression the macro that may have special characters should be enclosed in double quotes: JSONPath LLD macro value After substitution Good evening, I'm monitoring some switches with Zabbix. host in a trigger expression. See indexed macros. We currently have macros like {ITEM. If Zabbix server Expression macro User macro with context Example Some useful links Data Flow Data collection Data collection Zabbix Agent Problem detection Problem They correspond to Zabbix internal macros, they are represented using this notation {MACRO}, the complete list is available here. For example: The new 5. here ({SNMP_LINUX rNames. IF. In this case, more than one value may be processed. Note that when testing preprocessing steps in the frontend, macro values will not be pulled and need to be entered manually. X means "supported" in that location; The numbered macro syntax of {MACRO<1-9>} is used to reference hosts in the order in which they appear in a trigger expression. User macro. itemids. 0 I cannot get in Actions the Macros with latest entries working (which worked ok on Zabbix 5. Zabbix 1600px Default Style - Zabbix-- Zabbix 1600px; vB5 Style; Dark; Cloud; Blog; Trainings; Support . Implicit concatenation is the last thing to expect from numeric values in mathematical expression. lastvalue() > 15) and If Zabbix server/proxy was compiled with libpcre, this function will return UNKNOWN. So when we define global macros they will be overwritten by template macros and our template macros will be overwritten by host macros. 2. Get the output of a check and populate inventory (done) 2. HOST}")=1 It seems like macro is not expanded and just read literally. fallback,,,"{HOST. I'm aware that this macro can be used in the URL field of the HTTP Agent check Item, but going through this path will force me to create a ton of other items in order to achieve my goal, it would be definitely cleaner to throw everything inside a Javascript preprocessing step. 4 6 Expression macros. Attempting to then use this in the expression {INVENTORY. description: string: Description of the macro. Results show the status of each subexpression and total custom expression status. Context: The LLD is part of the VMware Guest Template provided by Zabbix, which automatically discovers virtual disks in the guest OS. Possible values: 0 - (default) Text macro; 1 - Secret macro; 2 - Vault secret. For example, you may want to extract the customer name and interface number from the following LLD macro for the purposes of event tagging: Since Zabbix 5. Closed; is duplicated by. The resulting data is stored in the Zabbix database as for any other item; both history and trend values are stored and graphs can be generated. May be used with a numeric index as {HOST. Let’s have a look at this example: Macros in Zabbix are key to building scalable architecture within Zabbix. Kindly help. I'm generally getting the hang of things, but I've reached a dead end that my google fu hasn't helped me resolve. Usage. Discovery found out (with cisco net template snmpv2) 9k items from which I only use 4k. Copied. VALUE<1-9>} and {FUNCTION. According to documentation , some functions are allowed as trigger event names. A LLD macro contains customer name and network interface number: Using macros in scripts. Triggers are not limited to a single item (metric) Zabbix supports a In the Test tab the regular expression and its subexpressions can be tested by providing a test string. Discover what has changed and why the Zabbix 5. And then create a LLD discovery list where I can create just one iten and change the number at the end by a regular expression so that it can pick up all the macros. We will cover: They correspond to Zabbix internal macros, they are represented using this notation {MACRO}, the Zabbix 5. The functions will be supported in all locations allowed for LLD macros. Use of host-level macro in the 4 Secret user macros. These previous values are handled by the preprocessing manager. In this post, I will explain how user macros 2 Trigger expression Overview. NAME} within a trigger expression like this: find(/BBU SNMP TRAPS/snmptrap. I haven't found any additional parameter I can provide to event. 8 Supported since 5. A simple expression uses a function that is applied to the item with some parameters. last()} {{HOST. Thanks The syntax in EXPRESSION is the same as in trigger expressions (see usage limitations below). For example, you may want to extract the customer name and interface number from the following LLD macro for the purposes of event tagging: Parameter type name value; Data set type: 0: ds. User macros and user macro context is supported for the tag name/value. 4 has introduced a new unified syntax for trigger expressions and calculated items (including aggregate calculations). You can use a normal regex though, just writing one in. Macro functions are supported with low-level discovery macros (except in low-level discovery rule filter), allowing to extract a certain part of the macro value using a regular expression. . Note that a macro with regular expression context can only be defined in user macro configuration. User is not allowed to create cannot perform regular expression "/Name=(\w+)/gm" match for value of type "string": pattern does not match I'm not sure how to get multiple values that match that expression. I am using expression macro {?last\host\key}, but all being shown as *unknown* in the mail alert. {#FSDRIVETYPE} macro on Windows is supported since Zabbix 3. Back to top. Zabbix supports number of macros which may be used in various situations. Effective use of macros allows to save time and make Zabbix configuration more transparent. For example, you may want to extract the customer name and interface number from the following LLD macro for the purposes of event tagging: If Zabbix server/proxy was compiled with libpcre, this function will return UNKNOWN. The function returns a result that is compared to the threshold, using an operator and a constant. All my agents are active, and I want to be alerted if a system goes offline for more than x minutes. In this post, I will explain how user macros and regular expressions are used in LLD for filtering the discovery results. You could just add the services you want to ignore to the existing expression that comes with Zabbix, but I have found it harder to get to work as expected. e. If pattern is not a correct regular expression then the macro evaluates to 'UNKNOWN' (excluding low-level discovery macros where the function will be ignored in that case and macro will remain unexpanded) If this is your first visit, be sure to check out the FAQ by clicking the link above. The order of the returned IDs matches the order of the passed host macros. If you are having problems with Zabbix, post here. It is possible to use user macros in JavaScript code. Cannot accurately apply filter: no value received for macro "{#IFNAME}". Can i build a new 5. incorrect expression" After reading what this macro does, it reads: "Name of the Nth item in the trigger expression that caused a notification. 5. Thus, when you have to make a change to all monitored hosts, for If a function is used in a supported location, but applied to a macro not supporting macro functions, then the macro evaluates to 'UNKNOWN'. Previous template Next. DESCRIPTION}. The rest I have manually disabled them. The issue with that is the macro will always point to the "name of the Nth item in the trigger expression". But it Hi, For quite some time we are struggling to reference expression macros in email messages sent in custom message's body when a trigger gets executed. hostids: ID/array: Return only macros that belong to the given hosts or templates. pattern - the regular expression to match output - the output options. RECOVERY. I tried to go the roundabout way. \1 - \9 placeholders are supported to capture groups. IP2}, {HOST. \0 returns the matched text. I have a trigger which checks for a specific keyword apearing in a log, and once triggered I was receiving the actual entry log {ITEM. To start viewing messages, select the forum that you want to visit from the selection below. str (<pattern>,<sec|#num>): Finding a string in the latest (most recent) value. The expression indicates the host, the item key and the parameter which is i'm having trouble with using {MACRO} expressions in link labels The following expression works perfectly fine when used in a host label as show here. Possible values: 0 - (default) Macro is managed by user; 1 - Macro is managed by discovery rule. HOST<1-9>} i {ITEM. If the function pattern is an incorrect regular expression, then the macro evaluates to 'UNKNOWN' (except for low-level discovery macros, in which case the function will be ignored, and the macro will remain When low-level discovery macros are used in JSONPath preprocessing and their values are resolved, the following rules of escaping special characters are applied: only backslash (\) and double quote (") characters are considered for escaping; When configuring monitoring and using templates in Zabbix you often see low-level discovery (LLD) used for finding out the monitored components or features of a host. I am using version 6. LASTVALUE2}. dataset_type: 0 - Item list; 1 - (default) Item patterns. 13 Storage of secrets. 2 Macros used in tag names and values are resolved only during event generation process. 4 I'd like to include the last value of a few other host items as operational data in a trigger. I tried to create an Item that Macro functions are supported with low-level discovery macros (except in low-level discovery rule filter), allowing to extract a certain part of the macro value using a regular expression. 1 Configuring a user. Go to Data collection → Hosts. Zabbix Documentation is licensed under the following license. To use calculated items User macros are supported in Zabbix for greater flexibility, in addition to the macros supported out-of-the-box. Even disabled, they do not disappear, from graphs, triggers, items, because they are still discovered. contain closing parentheses "``" or a comma. 1 CyberArk configuration. However, simple macros still have an old-style syntax {host:key. groupids: ID/array: Return only host macros that belong to hosts or templates from the given host groups or template groups. trigger names (since Zabbix 1. We must drop simple macros in favor of expression macros {? 2 Trigger expression Overview. 4, time_shift parameter supports multi-step time operations and may include /<time_unit> for shifting to the beginning of the time unit (/d - midnight, /w - 1st day of the week If pattern is not a correct regular expression then the macro evaluates to 'UNKNOWN' (excluding low-level discovery macros where the function will be You could even create a whole new regular expression rule and tie it back into the discovery rule. For detailed information on how date and time functions work within expressions, see Calculation time. Any idea on this. If Zabbix server/proxy was compiled with libpcre, this function will return UNKNOWN. ; Comments: If the function pattern is an incorrect regular expression, then the macro evaluates to 'UNKNOWN' If this is your first visit, be sure to check out the FAQ by clicking the link above.

Adding a description is also supported. In internet, and in Zabbix community all I've found it's info that this alert is appeared, when JSON data do not contain a value for the corresponding macro. Examples: concat (last(/host/key) I am attempting to use a macro in an item key expression for a trigger. Did fresh install of v4 as well as v5 same thing, not working. Note Currently, Zabbix doesn't provide good ways to debug trigger expression nor to put parts of trigger expression in alert messages in a convenient and unified way. Return global macros instead of host macros. Note that macro values can be kept as plain text, secret text or Vault secret. The indexed macro syntax of {MACRO<1-9>} works only in the context of trigger expressions. load[all,avg1]. Please report bugs here . User macros are supported in Zabbix for greater flexibility, in addition to the macros supported out-of-the-box. Before proceeding, set the StartVMwareCollectors parameter in Zabbix server configuration file to 2 or more (the default value is 0). Trademark Policy. Opti In this topic we will explain the different types of macros and how to use them. HOST} or {HOST. The method accepts host macros with the standard host macro properties. Hey all, Got a situation whereby I want to: 1. Items: 4: ds. Indexed macros. In the following locations: graph names; map element labels; map shape labels; map link labels; only a single function, from the following set: avg, last, max, min, is allowed as an expression macro, e. \1 - \9 placeholders are supported to capture groups. Macros like {HOST. We must drop Zabbix supports a {TRIGGER. For example: (myitem. LASTVALUE} Low-level discovery macros (except in low-level discovery rule filter) iregsub (<pattern Macro functions are supported with low-level discovery macros (except in low-level discovery rule filter), allowing to extract a certain part of the macro value using a regular expression. Each built-in macro can be used in one or more cases. IP} → Trigger-based notifications and commands → Problem update notifications and commands → Autoregistration notifications and commands → Internal notifications According to Zabbix documentation, a trigger is a logical expression that defines a problem threshold and is used to “evaluate” received data. Any ideas? Zabbix 4. HOST<1-9>} and {ITEM. Based on the trigger doc (and Macro doc) and other info I consulted, I expected something like this would work: Zabbix must support regsub() and iregsub() functions for LLD macros. num} Any idea of the issue here ? The values are periodically calculated based on the arithmetical expression used. If the regex: If more than one user macro with context exists, Zabbix will try to match the simple context macros first and then context macros with regular expressions in an undefined order. this is embarrassing. , templates linked directly to the host), sorted by Same here. VALUE}, which can be used in notifications to report the values of items and the whole trigger. get to get these macros expanded. It can be used to reference hosts in the order in which they appear in the expression. In each item's trigger there is a condition for the trigger occurs and we want to test the location in order to enable or not the trigger. In the Label field for the link, try adding an expression macro {?last(/ {HOST. NAME} macro without any additional clauses in expression. ID} macro to reference the original problem. 3. It is not as complicated as it sounds. I have a situation where I need to use a macro for a hostname in a calculated field. You can't use global regex in user macros. It is a really cool feature, and as soon as you understand how it works and what results you can get with it, you will start using it in all of your templates. This class is designed to work with host-level and global user macros. Implied multiplication would be more appropriate since it is a commonly accepted mathematical notation. You can use them to create complex logical tests regarding monitored statistics. IP3} will resolve to the IP of the first, Plain-text macro values are resolved; Where the field value (or part of the value) is a secret or Vault macro, the field will be empty and has to be filled out manually. Examples Example 1. Return values (object) Returns an object containing the IDs of the created host macros under the hostmacroids property. last(0)}) is used just to show you the process name. Effective use of macros allows to save time and make Zabbix The syntax of a macro function is: 1. VALUE<1-9>} and For instance, the action message that comes with Zabbix by default contains the following fragment: Item values: 1. User macros can be defined on global, template and host level. If you use {ITEM. VALUE} {ITEM. It also seems you can't set a user macro to be Zabbix 5. 0 template "Template Module Windows services by Zabbix agent active" uses the macro method, the old "Template OS Windows" template uses the regular expression method. 1. deleteglobal - delete global macros; usermacro.

Defining several filters is supported since Zabbix 2. When configuring the widget on a template dashboard, only items configured on the template should be set. Macros can be used almost anywhere within Zabbix and allow you fill an unlimited number of variable When configuring monitoring and using templates in Zabbix you often see low-level discovery (LLD) used for finding out the monitored components or features of a host. User is not allowed to create I want to check inside the trigger expression using the host name ({HOST. params - a comma-delimited list of function parameters, which must be quoted if: 3. Selecting more targets in this case only results in the command being executed on the La sintaxi a EXPRESSION és la mateixa que a expressions de trigger (veieu les limitacions d'ús tot seguit). IP3} will expand to the IP of the first, second and third When low-level discovery macros are used in JSONPath preprocessing and their values are resolved, the following rules of escaping special characters are applied: only backslash (\) and double quote (") characters are considered for escaping; i am trying to modify "Template Module Windows services by Zabbix agent active" which comes with new Zabbix 5. func(params)}. If a function is used in a supported location, but applied to a macro not supporting macro functions, then the macro evaluates to 'UNKNOWN'. Say, the macro I'm going to use is {HOST.

The table contains a complete list of macros supported by Zabbix: X means "supported" in that location; The numbered macro syntax of {MACRO<1-9>} is used to reference hosts in the order in which they appear in a trigger expression. HOST} Powered by a free Atlassian Jira open source license for SIA Zabbix. I want interface discovery filter, only trunks discovery, but the macro NET. It will allow to extract certain parts of LLD macro using regular expression. Create a host:. Yes, I can call trigger. I hope it will expand into value from host's description, say "my host description". In Calculated items, User macros in the formula will be expanded only if used to reference a function parameter or a constant; 6 Expression macros. They are calculated by expanding all macros inside and evaluating the resulting expression. Neste vídeo vou falar sobre expression macros, uma nova macro no Zabbix que pode ser utilizada para fazer calculos sobre os itens coletados e exibir o result Double-quoting the parameter is not necessary as Zabbix will take care of any ambiguous special symbols, if present in the resolved macro. {FUNCTION. User macros can be item key, function, operator or another trigger expression. *} macros can be used to reference host inventory values from one or several hosts in a trigger expression (supported since 4. 4 introduced a new syntax for trigger expressions and calculations. URL}. I want to edit macro Same here. For example, a value like 'Zab' concatenated to 'bix' (the constant string) will return 'Zabbix'. In the following locations: The syntax in EXPRESSION is the same as in trigger expressions (see usage limitations below). If a script contains user macros, these macros are resolved by server/proxy before executing specific preprocessing steps. If this is your first visit, be sure to check out the FAQ by clicking the link above. , templates linked directly to the host), sorted by Hi, we defined some macros in trigger's tag via LLD item. Configuring a recovery operation. pattern (optional) - required string sec or #num (optional) - maximum evaluation period 1 in seconds or in latest collected values (preceded by a hash mark).

I'm trying to define a macro with context, but this context is a regular expression. 6 Expression macros. ID<1-9>} to point to the first, second, third, etc. Thus, macros like {HOST. 6 Macros Overview. LASTVALUE} So, if you add an expression to the "Windows service names for discovery" expression, set it to "Result Is False" and set its value to "CDPIserSvc" all of these services will be ignored by Zabbix. Where x is < the system default By default, Zabbix has a global regular expression called "Windows service names for discovery". In the following locations: graph names; map element labels; map shape labels; map I was surprised to find I cannot (apparently) use the host name in a trigger expression. It contains an expression where the type is "Result is FALSE" and has an expression like this (not including the quotes) "^(sppsvc|MMCSS|gupdate|SysmonLog)$". If that info is available over API, you could run a script item to pull that name and run update command over API to fill up "visible name" and then use {HOST. ZBXNEXT-1473 Add new macro {FUNCTION. Zabbix resolves macros according to the following precedence: host level macros (checked first) macros defined for first level templates of the host (i. NAME2} in your macro message, it will always notify for the second item in the expression, even if the trigger was started for the first item. I wanted to compare the SNMP return for sysName against the current host name as a way of noticing if a device has migrated (e. Zabbix provides two options for protecting sensitive information in user macro values: Secret text; Vault secret; Note that while the value of a secret macro is hidden, the value can be revealed through the use in items. To keep things simple, I would create an additional expression in the default "Windows service names for discovery" regular expression to avoid changing the default regular regular expression string. 3 URLs that contain a secret macro will not work, as the macro in 2 Trigger expression Overview. Expression macros are useful for formula calculations. But it does not work. get - retrieve host and Note that a macro with regular expression context can only be defined in user macro configuration. 1. 2 Trigger expression Overview. You may have to REGISTER before you can post. start with a space or double quotes; 3. When low-level discovery macros are used in JSONPath preprocessing and their values are resolved, the following rules of escaping special characters are applied: only backslash (\) and double quote (") characters are considered for escaping; thanks for your suggestion, however as I am a total noob in Zabbix this might be a bit of an advanced topic for me to make it work in a reasonable amount of time. 2 Macros. This section allows to define system-wide user macros as name-value pairs. To configure a recovery iregsub(pattern,output) Substring extraction by a regular expression match (case-insensitive). Expression macros have a special These macros are variables, identified by a specific syntax: Macros resolve to a specific value depending on the context. 7 Supported since 4. x) . Use the {EVENT. I’m using the Network Generic Device by SNMP template as an example. g. 6 Simple macros may not be used inside each other. NAME}). Zabbix substitutes macros according to the following precedence: host level macros (checked first) macros defined for first level templates of the host (i. Hi. A simple expression uses I would like to display some data such as uptime, CPU usage , etc in email alert when there is a problem . VALUE<1-9>} macros can be used to reference function values of the trigger expressions and 1 Macros supported by location Overview. 0: Item ID. Obviously I spent a lot of time trying 1 Macros supported by location Overview. ; In the Host groups field, type or select a host group (for example, "Virtual machines"). LLD net. 9. A les ubicacions següents:- To resort to usable macros, you are forced to include needed value in your trigger expression (prev(/host/item). If any item parameter contains a secret macro value, the following warning message is displayed: "Item contains user-defined macros with secret values. <func>(<params>)} - macro functions trigger expression parameters and constants (see examples) The following characters are allowed in the macro names: A-Z, 0-9, _, . One of these tags is the name of the city where some network device is located. {HOST. But is properly working for Palo alto firewall. Hi guys, After upgrading to Zabbix 6. Atlassian Date and time functions cannot be used in the expression by themselves; at least one function from another group, referencing the host item, must be included in the expression (except the nodata() function). It's easy so overwrite a macro by accident to solve this problem Zabbix has the option on Host and on Template level to see if there are any macros defined yet with the same name. For example, you may want to extract the customer name and interface number from the following LLD macro for the purposes of event tagging: In the Label field for the link, try adding an expression macro {?last(/ {HOST. Supported since 1. Another approach I thought is to create a custom bash script, sending the data I want to Zabbix via the zabbix_sender command/tool. but if we could have a way to easely disable trigger (based on a macro or regular 6 Expression macros. If the function pattern is an incorrect regular expression, then the macro evaluates to 'UNKNOWN' (except for low-level discovery macros, in which case the function will be ignored, and the macro will remain Also Zabbix regex engine does not use GLOBAL parameter so you need to disable it on regex101 (same goes for multiline option) (on regex101 site on the right right of expression field there is /gm - click it and uncheck both options) ZABBIX FEATURE REQUESTS; ZBXNEXT-9323; Allow expansion of expression macros within trigger description Hi, I would like to know if there is a macro in Zabbix to retrieve the date of the last value ? In the doc, we can see : {ITEM. Calculated items may be referenced by macros or other entities same as any other item type. The table contains a complete list of macros supported by Zabbix. 0 template with regular expression? Chris edit: i have change the filter on the discovery rule and now it works again with regular expression. And/Or - uses And with different macro names and Or with the same macro name; Custom expression - offers the possibility to define a custom calculation of filters. The formula must include all filters in the list. service Perhaps I haven't found the right combination of quotes/parenthesis/etc, but when I try to use Zabbix built in macros, specifically {HOST. In the following locations: Note that for Change and Throttling preprocessing steps, Zabbix has to remember the last value to calculate/compare the new value as required. VALUE<1-9>} macros can be used to reference function values of the trigger expressions and So when we define global macros they will be overwritten by template macros and our template macros will be overwritten by host macros. Atlassian Expression macro User macro with context Example: Some useful links Data Flow Data collection Data collection Zabbix Agent การตรวจ They correspond to Zabbix internal macros, they are represented using this notation {MACRO}, the complete list is available here. func- the function to apply; 3. For instance, the action message that comes with Zabbix by default contains the following fragment: Macros are variables that can resolve to a specific value depending on the context and location inside Zabbix. (for more info, refer List of supported macros in manual) The description for that trigger may contain macros, which arrive in non-expanded form. A typical use case. : For that I tried to use expression macros in the "event name" field, but they are not resolving correctly. Hrmm actually, says users macros in context specifically.
