We use Icinga, but simple make sure the service is alive.

Someone from xcat will try to recreate. I am curious that how do you monitor 
the xcat service.

Using IBM Verse, send from my iPhone.

Probably yes. But the service was OK since then (we are monitoring the xCAT 
service status)

The start of xcatd looks failed to finish:
  Process: 7630 ExecStart=/etc/init.d/xcatd start (code=killed, signal=TERM)

Did you restart xcatd 16h ago?
  Active: failed (Result: timeout) since Tue 2017-06-06 19:12:36 CEST; 16h ago

Hello,



We are seeing some strange behavior with xCAT service –



Systemctl status xcatd return the following output –



s08:~ # systemctl status xcatd

● xcatd.service - LSB: xcatd

   Loaded: loaded (/etc/init.d/xcatd; bad; vendor preset: disabled)

   Active: failed (Result: timeout) since Tue 2017-06-06 19:12:36 CEST; 16h ago

     Docs: man:systemd-sysv-generator(8)

  Process: 30751 ExecStop=/etc/init.d/xcatd stop (code=exited, status=0/SUCCESS)

  Process: 7630 ExecStart=/etc/init.d/xcatd start (code=killed, signal=TERM)

    Tasks: 8 (limit: 512)

   CGroup: /system.slice/xcatd.service

           ├─23978 /usr/sbin/in.tftpd -v -l -s /tftpboot -m 
/etc/tftpmapfile4xcat.conf

           ├─28343 xcatd: SSL listener

           ├─28344 xcatd: DB Access

           ├─28345 xcatd: UDP listener

           ├─28346 xcatd: install monitor

           ├─28347 xcatd: Discovery worker

           ├─28348 xcatd: Command log writer

           └─28727 xcatd: DB Access





While xcatd is still running and operational (tabdump every other functionality 
seems to work).



Doing a systemctl restart xcatd immediately works and seems to fix the issue.



Any idea what could make the service thinks it failed? Anything we should look 
at?



THX!!
