Xymon Powershell Windows client
by lukas.kohl＠ergodirekt.de 16 Feb '15

16 Feb '15

Hello Zak, thank you a lot for your good work. The Script works pretty well, until now everything went exactly as it should. Our Xymon server is on Version 4.3.17, but our Windows Clients are still using the old BBwin Binary. So they are configured local. Is there any chance to have a localclient.cfg, which can be used by your Powershell Script, like we have on the Linux Clients ? Otherwise a migration to the new Client would be very painfull for us. Kind regards, Lukas Kohl

Running server-side custom test more often than every 5 minutes
by glauber.ribeiro＠experian.com 13 Feb '15

I have the a server side test that my manager wants to run once a minute. I set it up in (a file included by) tasks.cfg, like this: [VHRPING] ENVFILE /usr/local/xymon/server/etc/xymonserver.cfg NEEDS xymond CMD /usr/local/xymon/server/ext/bbvhr_rrd.sh LOGFILE $XYMONSERVERLOGS/vhrping.log INTERVAL 5m I changed this so the last line reads INTERVAL 1m but it still seems to be running only every 5 minutes. Is there anything else I need to change in order to run this test once a minute? (Xymon version 4.3.10) Thanks, glauber

Xymon 4.3.18 Released
by cleaver＠terabithia.org 13 Feb '15

13 Feb '15

Hello, Xymon 4.3.18 has been released to SourceForge (https://sourceforge.net/projects/xymon/) and should be populating on the mirrors shortly. 4.3.18 fixes a buffer overflow vulnerability in the acknowledge.cgi script (tracked as CVE-2015-1430). Thank you to Mark Felder and Martin Lenko for their assistance in this. This release also modifies the CGI interface to remove any dependencies on a shell interpreter, as a protection against any future "Shellshock"-type bash vulnerabilities. (Only users running bash as their /bin/sh interpreter would have been affected.) As a result, the Apache configuration for the web interface and your cgioptions.cfg file may need to be adjusted, depending on your configuration. Several other small bugs have also been addressed. For more details on those, see the Changes file in the distribution. Regards, -jc

Unless someone has a really nice DNS monitoring add-on that they can share, my suggestion for carefully monitoring DNS latency would be to use Smokeping: http://oss.oetiker.ch/smokeping/ It does a better job at DNS latency as it will send many queries over a shorter period of time and graph them in a really useful way.

Thanks Jeremy, I should use better word but all you guys are awesome and try to help. I am new this DNS world. Anyways the main thing to monitor the DNS latency. The other day some reason the DNS respond very slowly and many application timed out. And took me time to pinpoint caused by DNS so I want to tackle that issue on the future.

One is to extract metrics from the DNS server, typically by running "rndc stats" every 5 minutes or so, as per Richard's example. The other is to perform probes from another server (eg from Xymon) and look for performance or functionality shortcomings. I have a script that sends 100 lookups (using "dig") as rapidly as it can, and collects data about what it finds. It keeps counters of the number of no-error responses received, how fast it was able to send 100 queries. I then feed this into Xymon via data messages. > > >Unfortunately, due to intellectual property constraints, I can't share my scripts with you but I can offer advice to help you write and integrate your own scripts. >

Installing xymon/apache as a non-root user
by dl1025＠att.com 12 Feb '15

My company changed their policy to not give out root user access on their virtual environments. I need to install both apache, xymon and all related packages on the virtual environment running RedHat. The question is has anyone successfully installed xymon and apache as a non-root user that can share instructions of how to do that. I usually installed xymon and apache with root either manually compiling or using rpm but never as non-root. Any help will be greatly appreciated.

You should see graphs of DNS response times. If you want more detail than this, you need to do a bit more work. As Robert said, you need to define what you want to see. Even better is to specify the problem you're trying to solve, and then you're more likely to get responses that can help solve that problem. Are you wanting to monitor resolves or authoritative servers? I have a lot of DNS monitoring, but most of it is looking for specific metrics that relate to faults we have experienced, and they aren't generally useful for most installations. There are two ways I can think of to monitor DNS server performance. One is to extract metrics from the DNS server, typically by running "rndc stats" every 5 minutes or so, as per Richard's example. The other is to perform probes from another server (eg from Xymon) and look for performance or functionality shortcomings. I have a script that sends 100 lookups (using "dig") as rapidly as it can, and collects data about what it finds. It keeps counters of the number of no-error responses received, how fast it was able to send 100 queries. I then feed this into Xymon via data messages. Unfortunately, due to intellectual property constraints, I can't share my scripts with you but I can offer advice to help you write and integrate your own scripts.
