Mapping Values to Columns
by turranx＠hotmail.com 12 May '15

12 May '15

I have been looking at the relationships between values returned by client scripts and which web page column reports the status. Let me walk you through some of the data before I pose my questions. This is some output from a Windows machine running the PowerShell client... [memory] memory Total Used physical: 8073 5679 virtual: 12000 952 page: 20071 6710 Out of this data are extracted the values "MEMACT", "MEMPHYS", and "MEMSWAP". They are different measurements, but all affect the color of the column "memory". How they affect the memory column is well documented in the Man page for analysis.cfg, but what maps "MEMACT", "MEMPHYS", and "MEMSWAP" to the column "memory"? What if I wanted to add an additional custom memory-related test and have it also affect the color of the "memory" column? Furthermore, when a server is rebooted the "cpu" column goes yellow, but the column titled "uptime" always stays green. How do I change this? [uptime] sec: 1568818 18 days 3 hours 46 minutes 57 seconds Bootup: 20150420074804.610798-240 I've looked into custom server-side modules and that looks like a step in the right direction, but won't get me 100% of the way there. Can someone send me down the correct path? Thank you, Greg D.

xymon client - prevent monitoring of test
by ben.poppy＠mcis.com 11 May '15

11 May '15

We recently installed the client onto a debian system, and it is sending back alerts on apt and libs. I've been searching for how to prevent these from even alerting, but haven't been able to. Can anyone point me in the right direction on how to prevent the client from even monitoring those 2 columns?

(TS) Trying to setup xymon on a VoIP asterisk server
by dtsmon＠gmail.com 08 May '15

08 May '15

I have loaded a CentOS 6.6 server and installed PBX-in-a-Flash (PiaF) VoIP server on it. I then installed xymon on the same server and allow it to use VoIP and text-to-speech for certain urgent and or out-of-ban alerting. This is a home project for me. Before retiring is was monitoring 1,200 devices and using 'ssh' to move requests to the PiaF server for this function. I thought the next logical progression would be to use the same server for both functions. I am having the same problem that I have with just installing a CentOS server with xymon on it. I added the additional commands from the installation to the end of the http configuration file but I cannot bring up the xymon web page. In this installation, the apache runs under 'asterisk/asterisk'. Is there some directive that I am missing to allow apache to access the xymon pages in the xymon installation under the 'xymon/xymon' permissions? I have written many scripts that I cannot test out under the latest xymon software release and make available to the community. This is the same problem that I was having earlier and have not found the solution to. I also wanted to try allowing someone to be able to call into the VoIP side to retire an alert, etc. Thanks, Tom Schmitt

vagrant example of xymon-4.3.19 server (rhel6) + 3 clients (rhel6, rhel7, ubuntu14)
by marcin.dulak＠gmail.com 08 May '15

08 May '15

Hi, the example is available at https://github.com/marcindulak/vagrant-xymon-tutorial I hope Xymon's beginners will find it useful. In the process of creating it I noticed some problems with the documentation https://www.xymon.com/help/install.html: 1. RHEL6/7 documentation is missing dependencies: yp-tools c-ares-devel 2. Debian documentation is missing dependencies: libc-ares-dev dpkg-dev 3. I believe fping is no longer necessary as a dependency when building RPMS or debs 4. The /etc/init.d for xymon-client seems still missing on Debian/Ubuntu as reported here: http://comments.gmane.org/gmane.comp.monitoring.hobbit/30534 Best regards, Marcin

Email alerting for content check
by mburger＠bubbanfriends.org 07 May '15

07 May '15

Good afternoon, all. I'm running Xymon 4.3.19 and I've implemented content checking for specific URLs in my setup, but the actual process to alert, on screen, when the content does not match does work. The issue that I'm having is that Xymon isn't sending out the email alerts for that content check. So, my hosts file entry looks like this: page dorado Dorado xxx.xxx.xxx.xxx hostname.company.com # NAME:"Dorado Price Engine 1" NOCOLUMNS:conn,disk,files,cpu,memory,msgs,ports,procs,inode cont=content;https://some.url.to.check/subdir;"Sorry,[[:space:]]I[[:space:]]don't[[:space:]]speak[[:space:]]via[[:space:]]HTTP[[:space:]]GET" yyy.yyy.yyy.yyy hostname2.company.com # NAME:"Dorado Price Engine 2" NOCOLUMNS:conn,disk,files,cpu,memory,msgs,ports,procs,inode cont=content;https://another.url.to.check/subdir;"Sorry,[[:space:]]I[[:space:]]don't[[:space:]]speak[[:space:]]via[[:space:]]HTTP[[:space:]]GET" This works...I get column "content" and it goes red if the site does not return the text "Sorry, I don't speak via HTTP GET". My alerts.cfg looks like this: PAGE=%(dorado) MAIL list,of,recipients REPEAT=3 SERVICE=http,cont,content RECOVERED The xymonnet section of my tasks.cfg looks like this: [xymonnet] ENVFILE /apps/xymon/server/etc/xymonserver.cfg NEEDS xymond CMD xymonnet --report --ping --checkresponse --content=content,ptcls1,ptcls2,ptcls3,ptcls4 LOGFILE $XYMONSERVERLOGS/xymonnet.log INTERVAL 1m I've also tried this in my tasks.cfg: [xymonnet] ENVFILE /apps/xymon/server/etc/xymonserver.cfg NEEDS xymond CMD xymonnet --report --ping --checkresponse --content=content --content=ptcls1 --content=ptcls2 --content=ptcls3 --content=ptcls4 LOGFILE $XYMONSERVERLOGS/xymonnet.log INTERVAL 1m I'm at a loss...how do I make Xymon send out alerts on the actual content checks...what the heck am I doing wrong? -- Mike Burger http://www.bubbanfriends.org "It's always suicide-mission this, save-the-planet that.

Segmentation Fault (core dumped) with xymond_alert
by john.thurston＠alaska.gov 07 May '15

07 May '15

I bumped into this again today. I was working up some new alert conditions and tested them with: > xymondmd xymond_alert --config=foo.cfg --test foo.bar.com msgs --color=red It works as expected if foo.bar.com is defined, but if that host _isn't_ defined in the hosts.cfg, xymond_alert core dumps. For 4/3/17 on Solaris, the stack of the dump looks like: > fee12d10 strlen (37c93, ffbf50b4, 96164, 0, 0, 0) + 50 > fee81924 vfprintf (50190, 37c68, ffbf50a8, 0, a0ba4, fee81424) + ec > 0001a554 traceprintf (37c68, af7e8, 96160, 0, 50190, 4b800) + 84 > 0001c2fc criteriamatch (7, 55030, 0, 0, 0, 4bc00) + e4 > 0001e8b4 next_recipient (aff30, ffbf51a8, 0, 0, 4bc24, 4bc28) + 90 > 00017054 send_alert (aff30, 501b0, 0, ffbf51a8, 4bc00, ffff7fe4) + 17c > 00034550 main (0, 0, 0, 0, 501b0, aff30) + 1368 > 00014940 _start (0, 0, 0, 0, 0, 0) + 5c Granted that in production xymond_alert will probably not be fed an undefined host, but it would be nicer if it handled the condition a little more elegantly. -- Do things because you should, not just because you can.

Missing events on server's history page?
by betsy.schwartz＠gmail.com 07 May '15

07 May '15

Running xymon 4.3.17 , on linux, wondering if anyone's seen anything like this? for example our "edapps2-cf2" just alerted on cpu. The non-green view shows these most recent event Wed Apr 22 09:33:25 2015 edapps2-cf2.example.com cpu (yellow->green) Wed Apr 22 09:28:24 2015 edapps2-cf2.example.com cpu (red->yellow) Wed Apr 22 09:18:22 2015 edapps2-cf2.example.com cpu (yellow->red) Wed Apr 22 09:08:19 2015 edapps2-cf2.example.com cpu (green->yellow) When we go to the host page then cpu dot,and look at the full history we don't see them All log entries Date Status Duration Mon Apr 13 17:00:44 2015 8 days 16:40:47 (green) Mon Apr 13 16:45:41 2015 0:15:03 (yellow) Tue Mar 24 19:11:14 2015 19 days 21:34:27 (green) When we look at Reports/Event log they show up Wed Apr 22 09:43:45 2015 edapps2-cf2.example.com http green >From -> To yellow Wed Apr 22 09:33:25 2015 edapps2-cf2.example.com cpu yellow >From -> To green Wed Apr 22 09:28:24 2015 edapps2-cf2.example.com cpu red From -> To yellow Wed Apr 22 09:18:22 2015 edapps2-cf2.example.com cpu yellow >From -> To red Wed Apr 22 09:08:19 2015 edapps2-cf2.example.com cpu green From -> To yellow why aren't they on the host/cpu history page? thanks for any clues/explanation.

wrong memory report with free command from procps-ng
by Dominique.Frise＠unil.ch 07 May '15

07 May '15

Hi, Using Xymon 4.3.19, we noticed that all our RHEL 7 systems are reporting wrong values. These systems now use free from procps-ng 3.3.10 whose output has changed. -- free output on RHEL 5/6 --- [bb at prdexp ~]$ free total used free shared buffers cached Mem: 65916528 63391732 2524796 1376104 1484472 47773272 -/+ buffers/cache: 14133988 51782540 Swap: 16777212 180816 16596396 --- free output on RHEL 7 --- [bb at hns ~]$ free total used free shared buff/cache available Mem: 8011888 318844 3365516 98788 4327528 7275020 Swap: 8388604 0 8388604 The "-/+ buffers/cache:" has disappeared, the "used" is now calculated as total - free - buffers - cache, and there is an "available" column which is an "Estimation of how much memory is available for starting new applications, without swapping". The man page details all that. Dominique University of Lausanne

change alert email text?
by lts1809＠yahoo.com 07 May '15

07 May '15

I'm wondering if there is a quick answer on how to change the email alert text that Xymon generates. Specifically it is required that I remove the IP address from the email. Example: --- red Fri Apr 3 17:54:18 2015 conn NOT ok Service conn on 4ai1gub4x9 is not OK : Host does not respond to ping System unreachable for 223 poll periods (7274 seconds) &red 10.0.0.10 is unreachable --- would become: --- red Fri Apr 3 17:54:18 2015 conn NOT ok Service conn on 4ai1gub4x9 is not OK : Host does not respond to ping System unreachable for 223 poll periods (7274 seconds) &red 4ai1gub4x9 is unreachable --- I can list the IPs in the hosts.cfg (will have to actually, since no DNS server is available), but before I'll be allowed to submit Xymon to our security office for testing/approval to be added to our network management has tasked me with removing the IPs from the emails.
