xymondboard / nongreen page

Hi All, Can someone perhaps direct me on how it's possible to use the command line to generate / display all the hosts currently listed on the non-green page? Using the xymondboard with color=yellow or xymondboard=red seems to display considerably more than what is on the nongreen.html page. I'm looking to create a "dashboard" (outside of xymon) that monitors the nongreen.html page and lists how many hosts are listed there that do not have acknowledgements. Regards, Cami

Intelligent CPU Load Settings
by howe.bill＠gmail.com 30 May '16

30 May '16

Xymon'ers, Is there any planned functionality to be able to dynamically set a xymon client's LOAD alert settings based upon how many processors it has? The current static defaults are not too helpful, and hand editing an entry in /etc/xymon/analysis/*.cfg for every server just shouldn't have to be done. _*Ideally*_ It would be best if along with the "top" view that is reported by clients, they also reported their CPU count (either with "nproc" or "grep -c proc /proc/cpuinfo") Then the CPU count could be shown on client's "cpu" service page. <= Critical information when determining if load is a problem or not. Since the count would then be reported to and available on the xymon server, it could then be possible to set warnings and criticals based off of CPU count. (IE Warn at a load number equal to CPU count, Critical at a number equal to CPU count x 1.5) Regards, -- Bill Howe howe.bill at gmail.com

Devmon tests clear but snmpwalk works
by colin.coe＠gmail.com 30 May '16

Hi all I know this is the Xymon list not Devmon but I think I'll have most luck on this list so apologies in advance. I have a few of Cisco switches that I've just started monitoring at a couple of remote sites. snmpwalk works from the Xymon server but the Devmon tests are all clear (Devmon runs on the Xymon server). When I look at the devmon.log I just see lots of --- [16-05-26 at 20:19:09] No SNMP data found for ifName on swi02 [16-05-26 at 20:19:09] No SNMP data found for ifOutPktsSec on swi02 [16-05-26 at 20:19:09] No SNMP data found for ifOutCollisions on swi02 --- Any ideas on tracking this down? We have many if these switches at other sites and they display correctly in Xymon. Thanks CC

disk graph page limits total file systems
by EDSchminke＠Hormel.com 29 May '16

29 May '16

Another update for this topic: I added 100 file systems to a couple systems to see what would happen with the graphs. The target systems were different from the one that spawned this topic. When I added 100 file systems to a Linux (RHEL 6.6) system, all file systems were reported/graphed on the disk page. When I added 100 file systems to an AIX (v7.1) system, file systems were truncated; although at a different point. 120 of 132 file systems were represented.. I don't understand why they're so different. Comparing the df portions of the messages from each of the systems do not reveal any obvious differences. I'd really appreciate some suggestions for debugging. What commands I can run manually that the disk page is running internally. I've looked at the code, but haven't quite figured out what's going on in there; my C skills are rubbish. Erik D.

IT'S ALIVE!!!! Now for the fun questions......
by bigbandjohn＠gmail.com 29 May '16

Hi. Thanks to everyone yesterday. The quick response got my graphing up and running. I would be happy to document the CentOS 7.x install session when I do the official build and provide it for the wiki if anyone is interested. There are some minor differences with firewall commands and using services instead of the old initd vs. CentOS 6.x. Now I have 2 new questions - in the more general vein: 1) is there a bundle for the xymon client such that you don't have to build on every server you install on? The reason I ask is that most of our servers are barebones in production (only what is absolutely required). Mix of RHEL and AIX. Worst case I would bundle the directory which I made the client in between servers and do a "make install", but only as a last resort. 2) There are a couple administration add-ons for xymon. Would like advice if any are worth installing in your opinions. look forward to the feedback. John Lahngbein

i586, logfetch: ... delta NNN bytes exceeds max buffer size 0
by a_s_y＠sama.ru 24 May '16

24 May '16

Hello. I saw a strange problem since 4.3.26 (I not used versions between 4.3.16 and 4.3.26). 4.3.27 contains it too. 2016-05-23 14:44:14.052315 logfetch: /var/log/httpd2/error_log delta 2098854 bytes exceeds max buffer size 0; skipping some data 2016-05-23 14:45:54.580396 logfetch: /var/log/httpd2/error_log delta 2105418 bytes exceeds max buffer size 0; skipping some data 2016-05-23 14:47:35.120075 logfetch: /var/log/httpd2/error_log delta 2109847 bytes exceeds max buffer size 0; skipping some data max buffer size 0 somehow. I built i586 and x86_64 binary from one srpm. x86_64 works fine. Spec file is not contains architecture dependent parts. I see that this is macro in the client/logfetch.c (#define MAXCHECK 102400) and I don't understand how this is possible. Can anyone confirm the problem on i586 ? Log continues to be analysed however. -- Regards, Sergey

New to Xymon - having an issue
by bigbandjohn＠gmail.com 23 May '16

23 May '16

Greetings. I was a Big Brother user many moons ago and contributed many modules including for a database, a "multi module" and hot plug-in modules. In recent years I have moved away from the monitoring role, but recently have been thrust back into it. I am looking at many packages, and I am leaning towards Xymon as I like the "at a glance" dashboard for many of the people who may look at it. I am using CentOS 7.1 for my OS, and fairly quickly got it working at a basic level. The issue I am having is with data. I was going to deploy OpenNMS, but I noticed Xymon has graphing capabilities. One tool would be awesome. However, I am running into issues. I have tried installing all prerequisite RPM's, and even tried installing the packages via configure/make, but I just can't get xymon to find the graphing include files or libraries. I have done quite a few searches and nothing is really working for my case. I even used the --rddinclude DIR and -rrdlib DIR flags as it suggested with appropriate substitutions and pointing straight at it hasn't worked. I would really appreciate some help here. Perhaps I installed the wrong base configuration (webserver, no GUI). I am pointing to YUM and can download any packages needed. If I can download via YUM that would be preferred, but if compiling myself works better I have no fear or issue doing that. Once I get past this I am sure they will be happy with the tool and I can move forward installing agents, but my question concerning that can wait for another day. Thanks. John Langbein

I'm getting some errors that are making me nuts when I access the man pages for the cgi programs The apache log shows this: Options ExecCGI is off in this directory: /home/xymon/server/www/help/manpages/man1/ackinfo.cgi.1.html, referer: http://server.org/xymon/help/manpages/man1/ And of course, when I add ExecCGI I get: Premature end of script headers: ackinfo.cgi.1.html The server is scientific linux 6 Suggestions?
