Templates Triggers and (remote)actions

[Hans dmacron0]

Hi,

Sorry I always find it hard to write good titles.

What I mean is.

I want to monitor if httpd is running and if not it needs a restart.

Reading the manual I need to make a remote action like this:

host:/etc/init.d/httpd restart (and replace host with my servername)

or I can do this:

hostgroup#/etc/init.d/httpd restart

But I created a seperate template that just checks if http is down and if so it should somehow restart httpd on the server where it is down.

I created the item and the trigger and I have an action that can send a remote action.

But I have no clue how my trigger will execute my action. I do not see how to connect them.

The second problem,once I get actions working,is how can I tell the action script which host to use.

I really like to have one action script for restarting apache on the same type of servers. So the host needs to be passed to the action script somehow.

Does anyone have any suggestions how to do this or where to look?

thank you

Sorry, I was blind again.

I found the Action conditions.

So now I can link triggers with actions.

But that leaves the question of how to tell the remote action command which on host it should execute.

Hi back again.

I managed to change

host:/etc/init.d/httpd restart

to

{HOSTNAME}:/etc/init.d/httpd restart

Now it is actually restarting and emailing action info to me.

But now I have another question.

The restart script works perfect.

So just in case httpd crashes once a year I just need it to try a restart and only complain about it (ie send me a message) when the process is still down after say 15 minutes and I also want to know immediatly when it is back up.

When I look at the edit actions screen there is a column "delay" and it states immediatly. Again I have been searching hi and low where I can change this value. If I disable "Enable escaltions" that column is hidden.

Does any one have any suggestions how to do this?

Thanks

Hans

The following are my zabbix settings:
Agent side:
comment "Defaults requiretty" in /etc/sudoers
add line "zabbix ALL=(ALL) NOPASSWD: ALL" in /etc/sudoers

Server side:
remote command:
{HOSTNAME}:sudo /etc/init.d/lighttpd restart
action conditions:
trigger=lighttpd
trigger value=PROBLEM

When lighttpd trigger status is PROBLEM, the remote command will be send to {HOSTNAME} to be excute.

[bashman]

How can I "Run a remote command" on a recovery trigger?.

Zabbix activates maintenance mode for Zabbix GUI when iowait is high with a remote command, this are the action conditions:

(A) Trigger = "hostname:iowait"
(B) Trigger value = "PROBLEM"

And remote command works fine, but I want to deactivate maintenance mode when trigger recoveries.

Just like recovery message, but with remote commands, is it possible?.

[bashman]

Ok, just using condition Trigger value="OK" instead of Triger value="PROBLEM"
