running remote command

[thgnss]

Hi all,
I have some problems with remote command.
I'm monitorin a host named host1 e when the apache server is down I would restart it. So the action I configured for the remote command contain:
host1:sudo /etc.init.d/apache2 start
But when the apache trigger switch no action is executed.
Analizing the server log file through:

tail /var/log/zabbix-server/zabbix_server.log

and the output is:

3433:20100216:231956 Type of received value [1] is not sutable for [system.run[sudo /etc.init.d/apache2 start,nowait]@stefano] having type [-72515583] 3433:20100216:231956 Returning NOTSUPPORTED

Any help would be appreciated.
Thanks

I have a similar problem, I try to restart apache when it is down through an action.

First I grant permission to zabbix user to execute command without pass in visudo and EnableRemoteCommands in zabbix_agentd.conf.

Second, I configure remote command.

(hostname): sudo /etc/rc.d/init.d/httpd restart

So, i stop apache to test it, I see in dashboard that the action appears as sent, but apache continues down.

What can it be?? Permissions problem?

thanks

PS - in server log nothing appears, and now i realized that in client there is no zabbix_agentd.log but the agent is working.

I am testing in the zabbix server too but the same happens, service doesnt restart. In log appears this:

News, i have created another remote command that creates a file. echo 0 > /tmp/aaa.txt and the file is created well, so I understand nothing, remote command works for me creating file but not restarting services...

I continue my monologue, I realize that remote commands without sudo are executed well, but when I need to use sudo it doesn't work.

sudo echo 0 > /tmp/a.txt --> dont work
echo 0 > /tmp/a.txt --> work

The problem is that I dont know how to fix it, Zabbix user has permissions in sudoers to execute all commands without pass, i tested the commands before in a shell and work.

Any idea?

Problem solved.

I just have to comment out in visudo the line default requiretty.

Thanks

Thanks ! It worked perfectly without the "default requiretty" in /etc/sudoers
