2 Operations
Overview
You can define the following operations for all events:
- send a message
- execute a remote command (including IPMI)
Zabbix server does not create alerts if access to the host is explicitly "denied" for the user defined as action operation recipient or if the user has no rights defined to the host at all.
For discovery events, there are additional operations available:
- add host
- remove host
- enable host
- disable host
- add to group
- delete from group
- link to template
- unlink from template
- set host inventory mode
The additional operations available for auto-registration events are:
- add host
- disable host
- add to group
- link to template
- set host inventory mode
Configuring an operation
To configure an operation, go to the Operations tab in action configuration and click on New in the Operations block. Edit the operation step and click on Add to add to the list of Operations.
Operation attributes:
| Parameter | Description | ||||
|---|---|---|---|---|---|
| Default operation step duration | Duration of one operation step by default (60 seconds to 1 week). For example, an hour-long step duration means that if an operation is carried out, an hour will pass before the next step. Time suffixes are supported, e.g. 60s, 1m, 2h, 1d, since Zabbix 3.4.0. User macros are supported, since Zabbix 3.4.0. |
||||
| Default subject | Default message subject for notifications. The subject may contain macros. It is limited to 255 characters. | ||||
| Default message | Default message for notifications. The message may contain macros. It is limited to certain amount of characters depending on the type of database (see Sending message for more information). | ||||
| Pause operations while in maintenance | Mark this checkbox to delay the start of operations for the duration of a maintenance period. When operations are started, after the maintenance, all operations are performed including those for the events during the maintenance. If you unmark this checkbox, operations will be executed without delay even during a maintenance period. This option is supported since Zabbix 3.2.0. |
||||
| Operations | Action operations are displayed, with these details: Steps - escalation step(s) to which the operation is assigned Details - type of operation and its recipient/target. Since Zabbix 2.2, the operation list also displays the media type (e-mail, SMS, Jabber, etc) used in sending a message as well as the name and surname (in parentheses after the alias) of a notification recipient. Start in - how long after an event the operation is performed Duration (sec) - step duration is displayed. Default is displayed if the step uses default duration, and a time is displayed if custom duration is used. Action - links for editing and removing an operation are displayed. To configure a new operation, click on New. |
||||
| Operation details | This block is used to configure the details of an operation. | ||||
| Steps | Select the step(s) to assign the operation to in an escalation schedule: From - execute starting with this step To - execute until this step (0=infinity, execution will not be limited) |
||||
| Step duration | Custom duration for these steps (0=use default step duration). Time suffixes are supported, e.g. 60s, 1m, 2h, 1d, since Zabbix 3.4.0. User macros are supported, since Zabbix 3.4.0. Several operations can be assigned to the same step. If these operations have different step duration defined, the shortest one is taken into account and applied to the step. |
||||
| Operation type | Two operation types are available for all events: Send message - send message to user Remote command - execute a remote command More operations are available for discovery and auto-registration based events (see above). |
||||
| Operation type: send message | |||||
| Send to user groups | Click on Add to select user groups to send the message to. The user group must have at least "read" permissions to the host in order to be notified. |
||||
| Send to users | Click on Add to select users to send the message to. The user must have at least "read" permissions to the host in order to be notified. |
||||
| Send only to | Send message to all defined media types or a selected one only. | ||||
| Default message | If selected, the default message will be used (see above). | ||||
| Subject | Subject of the custom message. The subject may contain macros. It is limited to 255 characters. | ||||
| Message | The custom message. The message may contain macros. It is limited to certain amount of characters depending on the type of database (see Sending message for more information). | ||||
| Operation type: remote command | |||||
| Target list | Select targets to execute the command on: Current host - command is executed on the host of the trigger that caused the problem event. This option will not work if there are multiple hosts in the trigger. Host - select host(s) to execute the command on. Host group - select host group(s) to execute the command on. Specifying a parent host group implicitly selects all nested host groups. Thus the remote command will also be executed on hosts from nested groups. A command on a host is executed only once, even if the host matches more than once (e.g. from several host groups; individually and from a host group). The target list is meaningless if a custom script is executed on Zabbix server. Selecting more targets in this case only results in the script being executed on the server more times. Note that for global scripts, the target selection also depends on the Host group setting in global script configuration. |
||||
| Type | Select the command type: IPMI - execute an IPMI command Custom script - execute a custom set of commands SSH - execute an SSH command Telnet - execute a Telnet command Global script - execute one of the global scripts defined in Administration→Scripts. |
||||
| Execute on | Execute a custom script on: Zabbix agent - the script will be executed by Zabbix agent on the host Zabbix server (proxy) - the script will be executed by Zabbix server or proxy - depending on whether the host is monitored by server or proxy Zabbix server - the script will be executed by Zabbix server only To execute scripts on the agent, it must be configured (EnableRemoteCommands parameter enabled) to allow remote commands from the server. To execute scripts on proxy, it must be configured (EnableRemoteCommands parameter enabled) to allow remote commands from the server. This field is available if 'Custom script' is selected as Type. |
||||
| Commands | Enter the command(s). Supported macros will be resolved based on the trigger expression that caused the event. For example, host macros will resolve to the hosts of the trigger expression (and not of the target list). |
||||
| Conditions | Condition for performing the operation: Not ack - only when the event is unacknowledged Ack - only when the event is acknowledged. |
