Event History
by kconnell＠ryerson.ca 04 Oct '12

04 Oct '12

I built a new Xymon server this week with v4.3.7 and all looks good. Can I copy event history from my current Xymon/Hobbit v4.2.2 server to the new ? I did try copying files/directories over from /xymon/data/<hist>&<histlogs>, but that didn't seem to work...

Question on df processing for xymonclient-linux.sh
by Mark.Deiss＠acs-inc.com 04 Sep '12

04 Sep '12

In looking df processing in the Linux Xymon client module in client/xymonclient-linux.sh: echo "[df]" EXCLUDES=`cat /proc/filesystems | grep nodev | awk '{print $2}' | xargs echo | sed -e 's! ! -x !g'` df -Pl -x iso9660 -x $EXCLUDES | sed -e '/^[^ ][^ ]*$/{ N s/[ ]*\n[ ]*/ / }' A bit concerned that the df line can have a dangling "-x" option if the EXCLUDES variable is not populated. With a dangling "-x", the df command will abort with a syntax error and the df status will probably end up with a green status with no rrd history being populated. Users would not be aware unless they specifically brought up the green disk display or were reviewing disk trends and noticing the gap. The EXCLUDES variable can become null if the xymon client account loses read access to /proc/filesystems, for some reason the Linux flavor quit using the nodev tag (maybe started using NODEV or Nodev after a patch update....) or the xymon client went onto an (older) Linux version that did not use the /proc system. Suggest a revision either using sed or awk to build the EXCLUDES variable and a modification of the df command to eliminate the dangling "-x" option EXCLUDES=`cat /proc/filesystems 2>/dev/null | awk ' $1 ~ /nodev/ { printf("-x %s ", $2) }'` Or EXCLUDES=`cat /proc/filesystems 2>/dev/null | sed -ne ' /nodev/{ s/nodev[ ]*/ -x / H } ${ x s/\n//g p }'` df -Pl -x iso9660 $EXCLUDES 2>/dev/null | sed -e '/^[^ ][^ ]*$/{ N s/[ ]*\n[ ]*/ / }' If the parsing for nondev entries in /proc/filesystems now blows up for whatever reason (EXCLUDES is null), the df command will be capturing more than is desired which I believe would be preferred over missing the important file systems. Would like to use "2>&1" rather than "2>/dev/null" in the df line except any captured error lines may cause some downstream havoc with the rrd database processing.

Any alternatives to devmon?
by Paul.Root＠CenturyLink.com 09 Jul '12

09 Jul '12

Does anyone have an alternative to devmon? It's really old, doesn't seem to be being developed and the parsing of exemptions is flaky at best.

Trends clarification
by Michael.Beatty＠sherwin.com 31 May '12

31 May '12

I have a few questions as to what, exactly, I'm seeing on the "Trends" graphs. Xymongen and Xymonnet runtime.... Is this the time, in (mili)seconds that it takes for those processes to run on that system? In other words, if the Xymongen says 300m, does that mean it took 300 miliseconds to generate a webpage? And, if xymonet says 2 s, does that mean it took 2 seconds to run all of the network tests on that host? Incoming messages - My graph is showing about "625 m"... what is "m"? My average is 0.6 What does that number mean? Thank you. --

Thanks

Help with Xymon 4.3.7 runing Solaris x86
by Paul.Jacobs＠lchclearnet.com 29 May '12

29 May '12

Hi all, I have installed Xymon previously on Linux and had no problems getting the graphs to display on the web page but despite numerous attempts and lots of searching on the web I can't get them to be displayed at all on my Solaris x86 installation. They just appear on any browser like this below but there were no errors during installation and compilation. No errors in the apache logs either. I have gone to the demo site http://xymon.com/xymon/xymon.html and can see all the graphs fine and then drill down using the zoom fine. On my system I just get this message "Garbage ': 29-May-2012 14:36:38' after command: COMMENT:Updated: 29-May-2012 14:36:38" Any ideas as stumped?

e-mail alerts for a specific log? (Solaris 10)
by Nick＠Pettefar.com 29 May '12

29 May '12

Can anyone tell me how I can set up xymon so that specific (application) logs on specific servers send e-mail alerts (to several recipients)? I tried searching through the archives but could not find anything showing this. Do I have to configure (somehow) a different service? The servers run Solaris 10. I'm new to xymon. Nick
