Help. Service is stopped.

Hello, I have a Apache Karaf wrapper service running on centos 6. Past 2 days, the service stops automatically (atleast that's what I see). How can I find out what is the reason for this? Is it killed by os or something? It's a dedicated server.

Any suggestions how to identify the root cause why or how did the service stop?

Thanks

    Nothing is in the Apache karaf logs. How to see the system is logs and find out?

    You have a dedicated server and don't know that?

    hello @plumberg

    As root, type dmesg

    Also might poke around in various subdirectories of /var/log - might use the find command to list recently created or modified files

    For general purpose simple monitoring of system resources, install the atop utility. By default it should record a summary of stats about memory, cpu, disk i/o, network etc every 10 minutes.

    Well not my personal. It's a work server. The monitoring team notified me of service down. None of us in my team are sysadmin here, mainly developer. So we try to help in whatever ways we can. Thnx

    Sure thing. Thanks will try dmesg and poke around the logs folder. Anything else one may check? Thnx

  • Possibly also the journalctl command could help find log messages from service failure - the exact invocation would depend on the name of the service (as per the systemd unit) so you'll have to figure those details out for your setup

    Thnx. Looks like that's not available in centos6...
