[Xymon] Strange issue when using local scripts (in linux)

[David Boyer]

Jeremy,
       If you notice, both iterations are being run from the xymonsvr.
I've added the LANG to see if the
two report it differently.

So, by hand it looks:

[davieb at xymonsvr ~]$ ~xymon/client/local/dateinfo
dhcp-common,4.3.6,18 Jul 2020,en_US.UTF-8

Pulling the info out of xymon looks:

[davieb at xymonsvr ~]$ ~xymon/server/bin/xymon localhost "clientlog xymonsvr
section=local:dateinfo"
[local:dateinfo]
dhcp-common,4.3.6,Jul 18 17:44:26,*C*

Humm, there does appear to be a difference!  Checking the xymon user
itself, it UTF-8.
[xymon at xymonsvr ~]$ echo $LANG
en_US.UTF-8


That appears to be the issue though, I set the LANG=C and ran the script by
hand and get the same results when I pull it from xymon!
[davieb at xymonsvr ~]$ LANG=C;export LANG
[davieb at xymonsvr ~]$ ~xymon/client/local/dateinfo
dhcp-common,4.3.6,Jul 18 17:44:26,C

Looking at the xymon.sh start script, it does not appear to set it
anywhere!  Guess I'll need to run that
to ground in the morning.

Thanks for pointing me in the right direction!

Dave
