RE: [hobbit] Re: rrd history chart disappears under conn, memory and disk after 24 hours

I had similar symptoms a while back running Xymon on SLES 10.1 (SuSE

The rrd graphs would display data for hours 0-24 after a reboot, no data
for hours 24-48,

and then be fine again for hours 48+.



I determined that, when running under SLES, the uptime command returns
the string:

'day'   for uptime >= 24 hours && <48 hours; eg, 1 day

'days' for uptime >= 48 hours; eg 3 days


On the Xymon server, it appears the software is only looking for the
string 'days'.


I modified the [uptime] section in
~hobbit/client/bin/hobbitclient-linux.sh and added a perl 

command to change ' day ' to  ' days '.


echo "[uptime]"

uptime | perl -pe "s/^(.*) day (.*)/\1 days \2/"

I switch to version 4.2.3 and I haven't see the same issue.

I installed and configured xymon-4.3.0-beta2. Everything looks fine. But
there is one strange thing beyond my understood. The rrd history chart
disappears under tests/columns of conn, disk and memory after running 24
hours. But I can see these charts under column trends. No time effect to
the tests/columns of cpu and my custom tests. These rrd charts will stay
there as far as time goes.

If I add a new client, I can see these rrd charts under conn, disk and
memory during the first 24 hours (or the first day).

Anyone sees the same phenomenon?  Did I miss something in configuration?

Thank you in advance.
