Two columns (tests), one graph?
by waa-hobbitml＠revpol.com 04 Feb '14

Hi everyone. Using two custom external scripts, I have Xymon monitoring and graphing 3 temperatures from one device and 1 additional temperature from another device. Script(s) exist here: http://www.revpol.com/monitortemp Since the script was written to poll one device and up to 4 temperatures on that device, each device represents one column/test in Xymon with 1 or more temperature graphs using splitnvc. I'd like to combine all 4 temperatures on one graph - without rewriting my external script to poll both devices and report all 4 temps in one report if possible. Any hints, ideas? Thanks! -- Bill Arlofski Reverse Polarity, LLC http://www.revpol.com/ -- Not responsible for anything below this line --

Ping multiple IP addresses by name
by john.thurston＠alaska.gov 31 Jan '14

31 Jan '14

One of my hosts is multi-homed and I'd like to perform a ping test against both interfaces. Each interface has its own IP address and its own name. I'd like to avoid embedding ip addresses in my hosts.cfg. I've been able to get close to the behavior I want with: 0.0.0.0 foo.bar.com # conn=worst,1.2.3.4 but, of course, I have just embedded an IP address in my file I'd really like to refer to the second interface by its own name. It seems to ruin xymonnet to make the line look like: 0.0.0.0 foo.bar.com # conn=worst,goo.bar.com The conn result-page stops updating (even if I remove the name from hosts.cfg.) and I have to restart to make it start again I can come close the behavior I want by making my hosts.cfg: 0.0.0.0 goo.bar.com # nodisp 0.0.0.0 foo.bar.com # and adding a line to combo.cfg like: foo.bar.com.baz = (foo.bar.com.conn && goo.bar.com.conn) but then my combined test result appears as 'baz' rather than 'conn' and my tests are smeared across two files. Can anyone else suggest another way? -- Do things because you should, not just because you can.

You can add a text string at the end of the SVC statement SVC Symantec_AntiVirus startup=automatic status=started "TEXT=Symantec_Endpoint_Protection" It will display the text for the SVC so they are more human readable Mark Mulligan Associate Operations Engineer - Splunk and Xymon Admin P Please do not print this e-mail unless necessary

Additional Client messages

Hi, I have a number of hosts where I need to check the ps listing every minute and alert when something is wrong, but I dont want or need to run the rest of the client agent tests more frequently than the standard 5 minute interval. I thought the answer was to create a client extension to send another ps listing as a client message with a unique Collector ID and run this as frequently as required When I do this, I find on the server that the client data does indeed get updated every minute but the extra ps listing (which I put in a section called '[ps]') is not apparently processed against analysis.cfg. I know I can do this all on the client with a status message but I wanted to keep the configuration central and re-use the PROCS settings in analysis.cfg. Anyone any thoughts how to do this? -- Andy

Monitoring iostat performance

Thanks to everyone for your feedback! Figured I'd give this a shot, but I can't seem to diagnose what's going on. There's no apparent change in our xymon install. We're running 4.3.7. I've verified that both pl scripts are in the $xymonhome/server/ext/ directory on the server and $xymonhome/client/ext/ perl is installed, and the scripts are chown $xymonuser and chmod u+x. I've edited the scripts to use our company name instead of stanwell. (do you have an errant graph?) I'm assuming this would create an additional column on the overview page, or maybe an additional graph under trends....

I get a graph under "trends" but for some reason the graph comes up with numbers all being blank or "nan". I'm setting this up on a nonproduction server, so I've tried generating some disk activity to make sure it's not a divide by zero error or something. I wish my perl foo was a bit more up to snuff.

Monitoring iostat performance
by lists＠benjamindsmith.com 30 Jan '14

Recently, we had a publicly visible outtage as a result of one of our load balancers exceeding the IOPS capability of its system drives. We'd like to extend xymon (currently installed on CentOS6 /32 with defaults) so that it can monitor IOPS for all servers. Specifically, we'd like to see wrqm/s and probably %util. What's the most straightforward way to accomplish this? The other alternative is to create some form of internal script, which is doable but not preferable if there's an off-the-shelf tool available. -Ben

Do > I need to use something else? Not "mutt -x", that requires someone sitting at a terminal. Just plain MAILX="mutt" works fine with my mutt+sendmail+CentOS 6.3 test setup. I am not sure if it solves your problem with the weird characters. My normal mail client (Thunderbird) displays UTF-8 and UTF-16 characters without a hitch, but it does depend on the program you use to read the alerts, and on how the text is generated. Neither of those are within Xymon control. Regards, Henrik
