Hi JC-
Thanks for the response.
I am using Xymon 4.3.27 currently. The raw client data looks fine- there
are no corrupted lines and no added brackets or special characters that I
can see. This only occurs on the status pages.
The server has been running since May, and this particular problem started
at the end of Sept., after running Windows Update on my servers, but as
both Windows and Linux clients are showing the behavior, I have ruled out
the updates as the issue.
I have tried restarting the service with no effect on behavior and there is
nothing in the log files that show a problem that I can see. The level of
false positives due to formatting errors has remained relatively
consistent, and tends to be limited to the PROCS (Win, Linux) and SVCS (Win
only) tests, but occasionally will see the same error occurring on the DISK
and CPU tests, although that is significantly less frequent, and is not
across all configured machines. The PROCS/SVCS tests are showing random
errors on one machine or another approximately every 5 minutes.
Thanks
Greg.

to the xymon server. I have not made any changes to my client or server
configurations. Has anyone else been experiencing this behavior, or know
of a fix?

Hi Greg,
Is there anything unusual about the process names on the lines immediately
before the corruption? There's a known issue in that lines starting with a
bracket will cause missing data, and this can happen more frequently on
Windows servers just by virtue of some of the data that's coming across,
but that doesn't appear to be causing this specific issue.
Can you confirm which version of Xymon server you're using? Do you see the
same corruption in the "raw" Client Data for the affected servers, or is
it only occurring on the status pages?
Also -- anything unusual in the log files? Has this problem been constant
since it started, or is it getting worse? Does restarting the xymon
service fix it (temporarily)?
Regards,
-jc
