ZABBIX alarm execute remote command

daily Zabbix Call the police In the case , Most of them send emails to the police , It's rare in a scene to execute a command after an alarm ( Start the service 、 Clear disk space 、 Shut down The server ); And today I'll talk about what we need to do recently ： Execute remote command after alarm

First, let's talk about requirements ,  A distant day , My friends used mongodb, And it needs to be used vigorously , Some data will be stored in mongodb; Migrate data from the production environment into mongodb, So here comes the question , I often hear people say ,mongodb Hang up when the quantity is large .mongodb Some data is quoted in the program , I hung up sometime during the day , So users 、 Customer service 、 Operation is calling .. The team is also looking for problems , Find the reason , Ask the great God , Upgraded version , But I still hung up .. At present, if you hang up, you are starting .. Friends can't always be with computers , Sometimes I need to flirt with Mei Zhi 、 Go to the high ground . just zabbix There is a remote command function in the action , Then solve the problem through it ..

The whole process of remote command ：  items -> triggers -> action -> remote commands

The configuration process ：

1. Create a mongodb items

Configuration -> Hosts > Items

2. To configure mongodb triggers

Configuration -> Hosts > Triggers

3. Configure remote command actions

Configuraction -> Actions

The condition selection trigger value is PROBLEM、 The trigger is the above mongodb trigger

Execution times are 5 Time , Each interval 60 second

The type of operation is ： Remote command

The type is ： Custom script

command ： Specific instructions . The content will be posted below .

So far, the whole process is finished ,, But now mongodb Hang up ,actions Will execute startup mongodb Orders .？  Surely not. .

Remote command prerequisites , You need to enable remote command parameters in the configuration file , And start the agentd.

echo 'EnableRemoteCommands=1' >> /usr/local/zabbix/zabbix_agentd.conf

/etc/init.d/zabbix_agentd restart

# Be careful , Remote commands are not supported in zabbix agentd active Pattern .. Bear in mind ..

The script content ：

cat /usr/local/mongodb/start_mongod.sh

#!/bin/bash

/usr/local/mongodb/mongod -f /usr/local/mongodb/mongod.conf  >> /tmp/start.log

# Be careful ,zabbix Start the user , You need to be able to execute the above commands , That's what we need sudo Empowerment

So now , It's all done , Summarize the configuration process

1. stay agentd Open... In the configuration file EnableRemoteCommands Parameters

2. To configure actions Inside Remote Comand

3.Commands Script making in

Failure demonstration

kill mongodb

#killall mongod

After the collection time ,zabbix It will put triggers Set as problem, Trigger at the same time actions. The record shows the following

Administration -> Audit -> Actions

If the configuration is correct , that audit There must be a remote commnad Record .

Mistake 1,Audit No record , Check the configuration file 、actions To configure

Mistake 2,Audit Records , but mongodb But not started , There is a problem with the script , debugged ..

I hope this article can help you ,tks. - -
