Pandora agent daemon is not running //stops randomly
Hi,
I’ve installed Pandora FMS Server v5.1SP2.I’ve installed some agents on Ubuntu clients.
My problem is, that on some client the agent daemon stops randomly.
The log files dont say any information about the cause of stopping.If I restart the service it’s up and running again many hours until I have another crash.
Sorry for my bad english

Hello Kevin!
There is no messages file in /var/log
I’ve checked all of the log files in this directory, and there isnt any log message about pandora.I have also checked the agentname.data in /tmp directory, when i set the agent in debug mode, and i found everything is ok with the datas.
Kind regards,

Hi again,
Is there some kind of regularity in the issue (e.g, spikes in CPU usage shortly before the agent daemon stops) or does it trigger randomly?
Anyway, is this issue found in a single client, or in more than one? It might be a bad installation, which could be fixed by simply reinstalling the agent.Kind regards,
Kevin. -
Hi!
There is no any kind of regularity, CPU usage is ok, there is lot of available memory.
It stopped running randomly. Sometimes the running time is over many days with no problem, then stopped or running just few hours and stopped.I’ve 10 agents with the same installing package, and all of the agents have got this problem.
I’m using some bash script also on the agent, like special agent name (bash script generates the name), special modules (bash script gives the datas to this special modules).So its working well through many days, then daemon stopped.
I’ve installed agent with this intalling package to my pc (Lubuntu) and its work perfectly, never stopped for some weeks.

Hi again!
I’ve deleted my extra features from pandora agent, and installed again a “clear” pandora agent v6.0, but the agents still getting stopped after a few hour or day.
If I create a cronjob which checking pandora agent daemon and if it stopps the cron starts it again, but that would be greater if i could found out what is the problem.

Hi Kevin!
I’m running Ubuntu 12.04.2 LTS
Maybe one module is the reason, so i turn off the modules one by one, and listening when stoppes the agent daemon. But probably its not the reason, because it would cause always daemon’s stopping when the modules are refreshing.That’s strange that there isnt any log messages anywhere, that Ubuntu killed the daemon (syslog, kern.log)
Kind regards,

When I reinstalled the agent, I realised some dependency errors, like snmp and perl packages (I’m using some perl scripts on the agents).
The agents have no acces to the Internet, so I collected the dependencys and put them into the installing directory, where the agent installer deb is located also.
Can they cause the stopping?Kind regards,
Gadge. -
Hi,
I extended the agent daemon log, and waited for stopping.

Hello!
The agent has no access to the internet, so the dependencies were collected manually by one of my friend.
He didnt say any problem or missing dependencies during installing, but i’m not sure that all of them is collected or updated.
Does it cause the problem? Than why can run daemon and stopping after many minutes or days? -
Hi!
My pandora agent is using a perl script, which sends the restart command every 30 minutes (its necesserey because of my alt config)
The daemon stops during one of this restart period. The startup script (/etc/init.d/pandora_agent_daemon) makes stop than start command. The stop command is completed, then the script steps in the start command, where it returns whith the PID, which is not setted, so it has to start the pandora_agent. After the pandora_agent started, comes a sleep 2. In this place my script exist and pandora agent stops runningBest regards,
Gadge -
