Automatic service restart when some service down

[rizal]

Hi, I new user with Zabbix

I was configure and try zabbix from last week,
My Problem is how to automatic restart webserver e.g Apache2 on zabbix-agent when webserver is down.

My configuration is like that
Zabbix-server 192.168.10.107
Zabbix-agent 192.168.10.133
Availability on Zabbix-Agent was Z green and I can graph some service like cpu load, disk, utilization etc.

I was EnableRemoteCommands=1 on zabbix_agent configuration in /etc/zabbix/zabbix_agent.conf

In Zabbix Server, Web Dashboard, Configuration - Actions
Action tab,
name = Auto start apache2.

Condition tab,
type of calcuilation = AND.
condition label A Trigger severity = information
condition label B Host Group = Zabbix Servers (zabbix-agent was on group zabbix servers)

Operations tab,
operation type = remote command
target list host group = zabbix servers
type costum script
execute on = zabbbix agent
command = /etc/init.d/apache2 restart

Testing.
On zabbix-agent i was stop apache2 service, but i wait until 10 minutes apache not autorestart. I check log zabbix_agentd.log and zabbix_server.log but not find information about this case (Remote Command)

Anyone know how to set up remote command for automatic restart some services like apache2 when down on zabbix-agent.

I hope found the answer,

Thank you very much.

Hi! First sorry my english!!

In the zabbix_agentd.conf type LogRemoteCommands=1 for see logs from remote commands. After restart agent.

Verify if zabbix user have permission in your sudoers archive. If don't edit /etc/sudoers (visudo) and add line:
zabbix ALL=(ALL) NOPASSWD: /etc/init.d/apache2 restart

Make a test!

Verify when trigger started, in your Dashbord (Last 20 incidents), the action information if command worked or don't. If don't see zabbix logs. Probably the remote command will appear there.

I hope you can understand me and this may help in something.
