I have seen similar things for disk reports from Windows machines. I setup a cronjob to clean up the ones over a day old like this:

Delete RRD disk,ProgramData (Windows 10/11 Portable Base Layer sandbox

partition) over a day old, as name changes with reboots 0 0 * * * find /home/xymon/data/rrd/* -name disk,ProgramData\* -mtime +1 -exec /bin/rm -f '{}' \;

You could do a similar cronjob for your veeam snapshots.

It appears I have answered my own question

In the /var/lib/Xymon/rrd directory (I’m using Terabithia RPM version of Xymon) there were a large number of files with names similar to

disk,tmp,veeam,{f8dc516e-d17d-4a7e-b473-fd40e2d1a531}.rrd

these, as far as I can tell are veeam snapshots that are obviously being seen by the disk check and rrd file created but when there’s too many it crashed the trends column.

There were only two servers that had these excess files. I have now deleted them and all is working again.

Hi all,

On a couple of servers (maybe more) I get the following when trying to access the “trends” column

*Internal Server Error*

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

When I look in messages.log on the server I can see this

Feb 18 13:04:25 XymonServer kernel: svcstatus.cgi[3993679]: segfault at 1fe5965 ip 00007faddb3f79ad sp 00007ffd48ba9c60 error 6 in libc-2.28.so [7faddb369000+1cd000]

I’m unable to find an actual core dump file to help any further so am struggling to diagnose this one. Can anyone help?

Kind regards,

Neil.
