Re: [HTCondor-users] HTCondor and condor_ganglia issues

[pn <pn@xxxxxxxxxxx>]

More about condor_gangliad process:

I stopped condor (systemctl stop). and after that condor_gangliad was 
still there. I then killed it. And restarted condor after adding 
GANGLIAD to DAEMON_LIST. Sure enough condor_gangliad was one of the 
processes. But strangely, less than a second a second condor_gangliad 
appeared.

[root@simclu-ce ~]# ps -ea|grep gangliad
2592326 ?        00:00:00 condor_gangliad
2592334 ?        00:00:00 condor_gangliad

Would it be because I have a wrong configuration?

Secondly, Gangliadlog has this error:

07/27/21 21:40:23 my_popenv: Failed to exec âgstat, errno=2 (No such 
file or directory)
07/27/21 21:40:23 Failed to execute âgstat --all --mpifile 
--gmond_ip=192.168.55.79 --gmond_port=8652â: No such file or directory

What file is it complaining about? I replaced "gstat" with "/bin/gstat" 
and the error shows up again "Failed to exec "/bin/gstat, .."
