system.run versus remote command

[rbarrero]

Hi all;

I'm having a problem with Remote Commands (via Actions) but using the system.run function works perfectly from the server.

- RHEL ES 4.4
- zabbix 1.1.4
- debug level is set to 4
- sudo is configured properly for user 'zabbix' (tested thoroughly)
- EnableRemoteCommands=1

This works:
###
./bin/zabbix_get -s www.domain.com -p 10050 -k system.run["sudo /cluster/cluster-scripts/init.d/httpd-zabbix start"]
###

However, my Remote Command Action does NOT work.
"www.domain.com:sudo /cluster/cluster-scripts/init.d/httpd-zab start"

Here is the log from the server:
###
007031:20070302:000226 Run remote commands START [actionid:7]
007031:20070302:000226 run_remote_command START [hostname: 'www.domain.com', command: 'sudo /cluster/cluster-scripts/init.d/httpd-zab start']
007031:20070302:000226 run_remote_command [result:-2]
007031:20070302:000226 Run remote commands END
###

Seems like the result = -2. Does anyone know what this means?

We have taken a lot of time to make sure that init scripts return zabbix friendly output, permissions are correct, sudo is setup properly and we can execute remote commands as well. We have tested with the system.run()( command and it functions properly too.

Any help would be greatly appreciated.

Thank you!

Didi you try to specify full path to sudo?

[rbarrero]

Yes, I tried using the full path but still does not work. Here is the output from the zabbix_server log file:

###
007215:20070302:205312 Run remote commands START [actionid:7]
007215:20070302:205312 run_remote_command START [hostname: 'web.site.com', command: '/usr/bin/sudo /etc/init.d/httpd-zabbix start']
007215:20070302:205312 run_remote_command [result:-2]
007215:20070302:205312 Run remote commands END
###

Any other ideas?

Thank you!

Note: system.run() still works from zabbix server to the agent server.

Thanks,

Update

Hi;

Wondering if this helps... I found this error in the logs and thought it might be helpful in debugging.

"...
Type of received value [1] is not sutable for [system.run["sudo /etc/init.d/httpd-zabbix start",nowait]@www.site.com] having type [7233048]
..."

Ideas anyone?

Here are the raw log entries:


###

...more info and clarification

Hi again;

I just wanted to clarify something... my init script "httpd-zabbix" outputs only a "0" (success) or "1" (failure) to the screen. Is this correct?

Also, this works from the zabbix server:

/usr/local/zabbix/bin/zabbix_get -s www.site.com -p 10050 -k system.run["sudo /etc/init.d/httpd-zabbix start"]

Any reason why it doesn't work from the automatic action? Which in turn uses system.run()?

Thanks!

"nowait" vs "wait"

How can I specify "wait" or "nowait" for these system.run() commands via the Web Interface?

Using 'nowait' returns 1 while 'wait' returns 0... wondering if this makes a difference and how I can test with with the PHP interface.

[rbarrero]

Interesting find...

I see this in the zabbix_agentd.log file

"sh: sudo /etc/init.d/httpd-zabbix start: No such file or directory"

So it tries to execute the command with nowait, but it fails from the shell.

This file exists... so does the path. I have tried with /usr/bin/sudo and with just sudo.

Why is the shell failing on this when calling this command manually works?

Thanks!

Resolved

This was resolved by executing a remote command with no spaces.
