3 恢复操作

3 Recovery operations

概述

Overview

恢复操作允许在问题解决时通知您。

Recovery operations allow you to be notified when problems are resolved.

恢复操作支持消息和远程命令。恢复操作不支持通知升级 - 因为所有操作都分配到一个单独的步骤。

Both messages and remote commands are supported in recovery operations. Recovery operations do not support escalating - all operations are assigned to a single step.

使用场景

Use cases

恢复操作的一些用例如下：

Some use cases for recovery operations are as follows:

通知所有通知有关问题的用户

   * 选择“发送恢复消息”作为操作类型
       - 恢复时有多个操作：发送通知并执行远程命令
          * 添加发送消息和执行命令的操作类型
       - 在外部帮助台/票务系统中打开机票，并在问题解决时将其关闭
          * 创建一个与帮助台系统通信的外部脚本
          * 创建一个操作，该操作具有执行此脚本的操作，从而打开一张票据
          * 恢复操作，使用其他参数执行此脚本并关闭故障单
          * 使用{EVENT.ID}宏来引用原始问题

Notify all users that were notified on the problem

   * Select 'Send recovery message' as operation type
       - Have multiple operations upon recovery: send a notification and execute a remote command
          * Add operation types for sending a message and executing a command
       - Open a ticket in external helpdesk/ticketing system and close it when the problem is resolved
          * Create an external script that communicates with the helpdesk system
          * Create an action having operation that executes this script and thus opens a ticket
          * Have a recovery operation that executes this script with other parameters and closes the ticket
          * Use the {EVENT.ID} macro to reference the original problem

配置恢复操作

Parameter			Description
Default subject			Default message subject for recovery notifications. The subject may contain macros.
Default message			Default message for recovery notifications. The message may contain macros.
Operations			Recovery operation details are displayed. To configure a new recovery operation, click on New.
Operation details			This block is used to configure the details of a recovery operation.
	Operation type		Three operation types are available for recovery events: Send message - send recovery message to specified user Remote command - execute a remote command Notify all involved - send recovery message to all users who were notified on the problem event Note that if the same recipient with unchanged default subject/message is defined in several operation types, duplicate notifications are not sent.
		Operation type: send message
		Send to user groups	Click on Add to select user groups to send the recovery 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 recovery message to. The user must have at least “read” permissions to the host in order to be notified.
		Send only to	Send recovery 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.
		Message	The custom message. The message may contain macros.
		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 the command is executed on Zabbix server. Selecting more targets in this case only results in the command 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 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).
		Operation type: notify all involved
		Default message	If selected, the default message will be used (see above).
		Subject	Subject of the custom message. The subject may contain macros.
		Message	The custom message. The message may contain macros.
