IGNORE for DISK and INODE in analysis.cfg
by novosirj＠umdnj.edu 16 Apr '13

16 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, Quick question: does anyone know of an intelligent way to ignore both the disk and inode tests for a filesystem without adding two lines to analysis.cfg every time? I've noticed that a lot of the FS I excluded from the disk test have now returned (with all of the associated RRD cruft) in the form of the inode test now that I'm running 4.3.10. Thanks in advance for the tips. - -- - ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - Sr. Systems Programmer |$&| |__| | | |__/ | \| _| |novosirj at umdnj.edu - 973/972.0922 (2-0922) \__/ Univ. of Med. and Dent.|IST/EI-Academic Svcs. - ADMC 450, Newark -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEARECAAYFAlFswUwACgkQmb+gadEcsb52dwCfeFSq7JAh2T24jdY+wN+zIS8t 1wwAoLyGrE0FvOzvvUcNAPdEkKL8oF1b =bG8V -----END PGP SIGNATURE-----

Xymond_history
by majones＠mnsi.net 15 Apr '13

15 Apr '13

On Friday after over 800 days of operation our xymon server is reporting purple status for xymond_history. It says program crashed fatal sig caught. Yet the process is running and nothing shows in the log as a problem. Any ideas where I should start looking? Mark Jones

Monitoring that iptables and SELinux are running / enabled
by spah＠syntec.co.uk 15 Apr '13

15 Apr '13

Is there any code out there to monitor that (a) iptables is running (not just set to everything allowed) (b) SELinux is enabled I've looked on Xymonton, the Xymon archives and Google but not found anything. Obviously, checking that these are running is anywhere between nice and critical if one either has a server exposed to the Internet or need to pass regulatory security checks. The way I would ideally have liked these to work (but beggers can't be choosers!) is that the iptables check would work a bit like the port checks in analysis.cfg so one can check if particular rules are enabled (and the default policy on chains), and SELinux would also be monitored and configured in analysis.cfg with options to go yellow or red depending on the state of the enabled/disabled, permissive/enforcing and targeted/strict toggles. This then allows for sending alerts to managers if someone disables security measures on a server. Kind regards, SebA

backticks not working in client-local.cfg

Xymon version: - Xymon 4.3.10 OS: - Ubuntu 12.04 LTS **I am using the below entry but it is not converting the date command to the value. [server-name] log:/mnt/logs/access.`date +%Y-%m-%d`.log:10240 ignore INFO trigger SEVERE I tried many things but no luck, on the log page I see the date command as it is instead of the actual date value.: - log:`/mnt/logs/access.`date +%Y-%m-%d`.log`:10240 log:$(/mnt/logs/access.`date +%Y-%m-%d`.log):10240 log:$(echo /mnt/logs/access.`date +%Y-%m-%d`.log):10240 log:/mnt/logs/access.$(date +%Y-%m-%d).log:10240

FILE in analysis.cfg
by Paul.Root＠CenturyLink.com 12 Apr '13

12 Apr '13

So I'm creating a log file that will only get updated about every 3 months. But I want to watch that and make sure that it does get updated every three months. That part is easy. But, the file is only for our Linux machines, not our Solaris machines. Is there a way to tell analysis that I want to look for this file, but if it doesn't exist, that's ok? Or is there something like CLASS but for machine type? Oh, and I'm also monitoring a handful of linux machines for others outside my group, that won't have this file. And if I just put in the FILE line, it's going to tag those machines with file doesn't exist, if I put it in HOST=*. And I don't really want to put it in, individually, for the 90+ machines I do have, and the ones I'm adding weekly. The vast majority of my machines do have a 3 character start, so I guess I could use those... Any better ideas? While, I'm at it, is mtime> only in seconds or can I put a 'd' modifier for days on the end of it?

Checking disk space on a "backup" system
by Michael.Beatty＠sherwin.com 11 Apr '13

11 Apr '13

All of the hosts that I will be monitoring have a backup. This backup is, for most all practical purposes, idle. It does nothing but sits and wait for someone to move it into production. The primary system copies files and database exports over to this backup system. I had no intention on running a Xymon client on these backup systems (though one would be installed and waiting to be started), the only monitoring is a ping test. With that said, one exposure that exists on these backup systems is that the disk space in the file system has the potential to fill up. Is there any functionality built into xymon that would let me check the disk space on this remote system and report it back from the primary system? My initial thought was to write an extension script that does an 'rsh backup du /home/user/' and parsing the results and test against a threshold, but I would prefer to utilize what is built into xymon before recreating the wheel. Thanks -- Michael Beatty

Xymon Server in Debian
by dannyroberts.personal＠googlemail.com 11 Apr '13

11 Apr '13

Hi Folks, I am currently testing out Xymon and using Debian as both the server and client in my tests. I installed both xymon clients and the xymon server from the Debian repo rather than using the .deb from the xymon site or compiling from source. I have a couple of issues that may be Debian sepcific, I originally asked this question on the Debian forums ( http://forums.debian.net/viewtopic.php?f=5&t=103076) but got no response. 1. I created a user using "htpasswd" so that I could access the cgi sections of the web server, however I am never prompted for a username/password so still cannot access these sections. 2. I was looking for hosts.cfg to setup monitoring of diskspace and the like but the file does not exist under /etc/hobbit where I expected it. In-fact any file mentioned on this page does not seem to exist: http://xymon.com/xymon/help/xymon-config.html This second point in particular makes me think Debian is doing something odd with packaging and file names etc. Any help is greatly appreciated. -- Kind Regards Danny R Website: http://danny-roberts.info/

Alert Recovery question
by tlewick＠apsaranetworks.com 11 Apr '13

11 Apr '13

Does Duration work with Recovered in alerts.cfg. Meaning, is there a way to tell xymon not to send the recovered message until the link/device/threshold is back to recovery level for at least some time, i.e. 1 or 5 minutes? Thanks, Taylor
