    Posted by rkiesler on abril 12, 2024 at 17:38

    Hi! Until 2 days ago, pandora agent sent its data nicely to my pandora fms community server. Now, after upgrading Home Assistant running on the same machine, apparently, it is no longer doing that. According to the “debug 1” setting in pandora_agent.config, the XML is generated nicely. But the Pandora FMS console is telling me UNKNOWN for all the sensors.

    This happens just for one of my pandora_agents, the others are still working fine. I tried installing pandora_agent again with force install — no difference. Please help! Thanks!

    server / console / agents are all running on a Raspberry Pi. agent on one Raspberry Pi, server / console on a different one. All of that running Raspbian.

    Hi Rkiesler,

    It seems to be a problem with the shipment check the following:

    1. That you have added a module that corrupts the use of the agent (in that case remove it).

    2. That there is no firewall or proxy blocking the traffic from the agent to the server.

    3. That the agent machine has a direct connection to the Pandora FMS server.

    Another option to see if it is working correctly, do the tentacle sending test from the agent machine to the Pandora FMS server.

    I attach the command for you to make the appropriate tests.

    Linux:

    tentacle_client -a IP_PANDSERV  FILEPATH

    Windows:

    tentacle_client.exe -a IP_PANDSERV FILEPATH

    The file that you send should arrive to the directory “/var/spool/pandora/data_in” in the Pandora FMS server.

    Best regards,
    Víc.

    $ tentacle_client

    -bash: tentacle_client: command not found

    UPDATE: Found it, it’s in /opt/pandora-agent/usr/bin, just where I installed it 🙂

    yes, the file arrived and is in the directory you have mentioned. but all the 47 sensors of that agent are still in status UNKNOWN.

      Hello rkiesler,

      If the tentacle_client is not found in the $PATH of the system, then the server won’t be able to execute this normally, as it will look for this binary at the $PATH.

      Make sure you have the path of the tentacle_client declared inside the $PATH env var of your system in order for PandoraFMS to be able to run the binary and send the XMLs.

      Kind regards,

      Sergio B.

    Thank you! tentacle_client is now reachable by PATH, but it is still not working. Further investigation — in /opt/pandora-agent/tmp I get exactly one .data file, each time I reboot that machine — that’s it. I think, pandora_agent is stuck and probably that’s why it doesn’t send any data.

    example: 7a535e6f2c8c9336c0fdc4dd81121fbd.1713203128.data

    I’m not sure what’s going on here.

    In the log file, I get this information:

    Hi rkiesler,

    If you activate the debug mode in the agent, do you get any error in the module executions or is there any module that takes much longer than the agent interval?

    Check the agent’s log or attach it so we can take a look at it (if the agent has any sensitive data, you can send it to us privately).

    Best regards,
    Víc.

    Hi, no, the execution seems to only take a couple of seconds and the XML also looks good. Here’s the debug log:

      Not sure why, but it’s working now. Thanks!
