Run Remote command on the Zabbix

Zabbix Host

• To accomplish the task in which we get the details of Processes which consumes the CPU, memory and SWAP usage. For that purpose I created a script which gets the top 10 processes which consumes the memory,cpu and swap
• To enable the remote command on the zabbix host, below are the commands
• #cd /etc/zabbix
• #vi zabbix_agentd.conf
• Find the line EnableRemoteCommands, uncomment it and enable it by give the bit equal to 1
• Restart the zabbix agent (#service zabbix-agentd restart)
• Give the write permission to the folder where we have placed script.
• #chmod g+w /etc/zabbix/bin (bin the dir where all the scripts placed)
• In bin dir I placed my scripts which is being used by zabbix to run them through zabbix agent 

Zabbix GUI

• Under the Configuration Tab Select Action tab and create the action
• Create new condition in which trigger name like the memory trigger value

• Create the new operation in which the remote command executes on the respective target and under the comment section mention the command which we want to run under the Zabbix host agent

The remote commands here is mem.sh (script). In that script I am getting the result of top 10 processes which consuming my system memory,CPU and swap. The script ran whenever the memory trigger get fired as it is linked with the trigger name.

Below is the result which I get in the email:
