[xymon] rrd history chart disappears under conn, memory and disk after 24 hours

Wed Jul 21 15:20:17 CEST 2010

Ryan,

 Your 'uptime' command is returning ' day, ' <-- note the comma ','
after the 'y'

Change statement to:

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

or

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

Note: ' day ' --> ' day, '

# echo '10:40:28 up 1 day, 41 min,  4 users,  load average: 0.02, 0.04,
0.00'| perl -pe "s/^(.*) day, (.*)/\1 days \2/"

10:40:28 up 1 days 41 min,  4 users,  load average: 0.02, 0.04, 0.00

Hi Josh,

I did modify hobbitclient-linux.sh as you instructed but I think there's
no change as I tried it manually.

[xymon at xymon ~]$ cat /etc/redhat-release

CentOS release 5.4 (Final)

[xymon at xymon ~]$

[xymon at xymon ~]$ uptime

10:40:28 up 1 day, 41 min,  4 users,  load average: 0.02, 0.04, 0.00

[xymon at xymon ~]$

[xymon at xymon ~]$ uptime | perl -pe "s/^(.*) day (.*)/\1 days \2/"

10:40:42 up 1 day, 41 min,  4 users,  load average: 0.01, 0.04, 0.00

[xymon at xymon ~]$

[xymon at xymon ~]$ echo `uptime | perl -pe "s/^(.*) day (.*)/\1 days \2/"`

10:40:53 up 1 day, 41 min, 4 users, load average: 0.01, 0.04, 0.00

Thanks and regards,

Ryan

Ryan,

 I don't have a CentOS system to test on.  

I would expect CentOS to use the  hobbitclient-linux.sh script too, so
the fix described below should work for you too.

On the client, edit hobbitclient-linux.sh and change:

echo "[uptime]"

uptime 

To 

echo "[uptime]"

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

Hi Thomas,

Good day!

I am having the same issue, but the problem is that it is my Xymon
server that is installed on CentOS that is displaying 'day' instead of
'days' when executing uptime command.

So all my clients' graph are not displaying after the time that you
specified on your email.

Can you help me on how to solve this problem?

Thanks in advance.

Best regards,

Ryan

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

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 have been running two Xymon- 4.3.0-0.beta2 running on  RedHat AS 5.2
servers for over three months and hive not seen anything like you
describe on either server.

Hi,

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

Thanks.

Hi,

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.
