Analysis of Linux Zabbix custom monitoring and alarm implementation process

Target

Display one of the data in the iostat command in the zabbix front-end monitoring.

iostat Command

The iostat command is used to monitor the usage of system input and output devices and CPU.

Here we take out the tps item of disk sda. Note: tps: Transactions Per Second, the number of transactions processed per second.

Add monitoring items on the monitored end

Create the file iotps.conf under /etc/zabbix/zabbix_agentd.d

The format of custom monitoring items is: UserParameter=<key>,<shell command>

Restart the service: systemctl restart zabbix-agent

examine:

Test whether the client-defined monitoring items are normal on the monitoring end

Install the check tool: yum -y install zabbix-get
