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

["Ryan Novosielski" <novosirj (at) umdnj.edu>]

Is anyone else getting Tom's e-mails over and over and over? I probably am more sensitive to this as I see my name on the first line and think it is important. :)

Ryan,

 

 Your âuptimeâ command is
returning â day, â Ã note the comma â,â after the âyâ

 

Change statement to:

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

or

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

 

 

Note: â day â Ã â day, â

Hi Josh,

 

I did modify
hobbitclient-linux.sh as you instructed but I think thereâs 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 donât 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 âdayâ instead of
âdaysâ when executing uptime command.

So
all my clientsâ 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:

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

âdaysâ for uptime >= 48
hours; eg 3 days

 

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

 

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

command to change â day â to  â days
â.

 

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.
