Xymon 4.3.2 http flapping with SSL error
by pmeech＠gmail.com 23 May '11

23 May '11

Hi All, I seem to have a bit of a problem with a large amount of devices reporting http flapping. I am monitoring in hosts.cfg https://[ip_address]:444. The SSL column always remains green, but the http column flaps with the status message: https://[ip_address]:444/ - SSL error Seconds: 5.08 Is there anyway the time that the http test awaits a response for can be increased, or is there any other way to prevent the flapping/red status? I have 90 such devices that consume a lot of RAM and the CPU regularly goes up to 90%+ (I collect SNMP stats via devmon so the flapping here can be controlled with thresholds). I presume this is why the http response can be slow, though it would normally return in 8s. Hence the question, can the http reponse time to Xymon be increased? Cheers, Phil

Hobbitd crashing
by betsy.schwartz＠gmail.com 22 May '11

I was playing around with hobbit-clients.cfg file trying to create a LOG rule to ignore this alert: May 21 00:54:21 redirect1-bo3.dl2.example.com monit[2029]: [ID 111343 daemon.error] 'gmond-sample.xml' timestamp test failed for /usr/local/Ganglia/logs/gmond-sample.xml I **think the rule that put it into conniptions was HOST=%redirect.*bo3.dl2.example.com LOG /var/adm/messages COLOR=yellow IGNORE=%(repeated|gmond|monit|puppetd) Also, I am experiencing something I've seen a few other times this week - a service that is not reporting, that was signed out, stays blue even when signed back in. I can't get rid of the xymond_client blue. Where is blue status stored? (it does not appear as blue on the enable/disable page but I have a blue dot on the host page and a blue report when I drill in) [xymon at netmon2 server]$ gdb bin/hobbitd_client tmp/core.24453 GNU gdb (GDB) Red Hat Enterprise Linux (7.0.1-23.el5_5.2) Copyright (C) 2009 Free Software Foundation, Inc.

Logn Poling Interval icon color goes into "purple".
by jayantak007＠gmail.com 22 May '11

22 May '11

Hi All, I configured KPIs in client side. My poling Interval is 120 minutes. In "clientlaunch.cfg" file I had given “INTERVAL 120m”. But every 30 minutes KPI color got changed into “purple” color even there is no status change in the same KPI. Kindly let me know how I can resolve the problem. With Regards, Jayanta.

xymon 4.3.3 svcstatus
by icepickjazz＠gmail.com 22 May '11

22 May '11

I copied the svcstatus.c file from the 4.3.2 distro to the 4.3.3 and recompiled and resinstalled. svcstats works fine now. Need to figure out why 4.3.3 svcstatus.c is doesn't work.

Core dump in showgraph.cgi with very large "service" name
by jlaidman＠rebel-it.com.au 20 May '11

20 May '11

Hiya One more bug that I can't track down where to fix. If I go to a "showgraph" page and change the "service" value to something ludicrously large (2k or more), then showgraph.cgi dumps core. It happens at different places depending on the size of the value, so presumably there's a buffer being filled by different things, and one of them pushes it over the limit. Sorry I couldn't be more help on pinpointing the problem. Cheers Jeremy

SMTP test needs much more capability
by hobbit＠elyograg.org 20 May '11

20 May '11

I have been chasing down the following. The first is the smtp status reported on the xymon status page (which is green), debian package version 4.3.0-0.beta2. The second is a corresponding message from mail.log on the Postfix (2.7.1 debian package) server. 220 nexus2.example.com ESMTP Postfix (Debian/GNU) 503 5.5.1 Error: send HELO/EHLO first 221 2.0.0 Bye May 20 10:08:15 nexus2 postfix/smtpd[8689]: improper command pipelining after MAIL from mcp.example.com[10.2.1.39] After a lengthy exchange with Wietse Venema on the postfix-users mailing list, I got to the bottom of it, and there's no problem with postfix. The 503 error is because Xymon does not send a HELO. I've determined that if I send the following, I can avoid the 503 error: helo xymon mail from: xymon at example.com quit If I modify the smtp test to send these strings, the "improper pipelining" message is still logged. This is because Xymon is breaking SMTP rules by not waiting for the response to each command before sending the next one. There are no longer any errors logged during the actual SMTP session, because I have added the xymon server to a list that allows it to get away with improper pipelining, and to another one that lets it send invalid HELO strings and FROM addresses. This would be a problem if I had to monitor a remote postfix server whose configuration I could not control, though. The only reason that the test passes is that the string it looks for (220) is returned in the initial banner, before any SMTP commands are sent. It is not actually a real test. Any number of postfix configuration errors would keep the server from working, yet still return the banner on initial connect. Does anyone know how to make Xymon smart enough to wait for a defined response on each command before sending the next, and to put custom commands into a config file, rather than built in at compile time via protocols.cfg? Ideally it would be able to understand that any 4nn or 5nn code is a problem as well. I will take a look at the code, but my programming skills are rusty. Thanks, Shawn

acknowledge alerts with email (postfix)
by fs＠rnt.de 20 May '11

20 May '11

Hi I've installed Xymon 4.3.3 on Centos 5.6 with postfix. Everything is working fine but I can't acknowledge alerts with email. I see the email is coming to the default location from postfix (/var/mail/xymon) and nothing happened... Is there a howto or has anyone an idea how to configure this ? Thanks Best regards Frank

Custom Non Green Displays
by willowbrookmagic＠hotmail.com 19 May '11

19 May '11

Is there a way to create multiple custom non-green displays? I have a large environment where each department is only concerned with thier own devices. i tried creating a wintel-nongreen.sh #!/bin/sh # This uses the statusreport.cgi to provide a list # of all non-green statuses with a brief summary of what is wrong. . /opt/admin/xymon/linux/current/server/etc/cgioptions.cfg exec /opt/admin/xymon/linux/current/server/bin/statusreport.cgi \ --filter="color=red,yellow" --all \critwin\* --heading="All non-green Wintel systems" \ --show-column \ --show-summary \ --link But I think i'm missing something.

Alerts variables
by johan.sjoberg＠deltamanagement.se 19 May '11

19 May '11

Hi. I am trying to improve the html e-mail alert script a bit. I want the background to be blue if the cause of a recovery is a disable. Is there some variable sent to the alert script that indicates that a disable is the cause of a recovery, or do I have to create logic for this in the script, guessing based on the colors in the status message? /Johan

suggestion for xymonclient-sunos.sh under solaris 10.
by rbadillarx＠gmail.com 19 May '11

19 May '11

Hi all: I have noticed that xymonclient-sunos.sh code on version 4.3.3 change to get rid of mac and wsrmd nics. A nice change; but also the use of kstat on solaris cotainers (zones) can misguide people who read the trend graphics since kstat prints out all the nics of the equipment nor zone's configured nics. So I humbly posting what I think can "fix" (talking about voiding misguiding) since I have solaris containers with one, two or three nics (yes subinterfaces associated to physically different nics)..also I think can be use on 4.2.3 clients. 56,58d55 < ONZONE=`zonename` < if test "$ONZONE" == "global" < then 61,64d57 < else < MYNICS=`netstat -i |cut -f1 -d" " | egrep -i -v "Name|lo|^$" |paste -s -d"|" - ` < /usr/bin/kstat -p -s '[or]bytes64' | egrep "$MYNICS"| sort < fi Any comment; welcome! --Randall Badilla.
