SMTP test needs much more capability
by hobbit＠elyograg.org 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)

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

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

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.

Hi All, Please advise if there is some sort of plugin/script that will send a message from the client when my backup application sends me an successful/unsuccessfule email after my backups and update the Xymon page. Im currently using Attix 5 as my backup application. Is this possible ? Thanks -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

flapping status color
by lebarber＠gmail.com 19 May '11

Is it possible to make network tests report "yellow" when flapping occurs? This would solve a problem I've been having, seems some admins here don't think flapping is a problem. I disagree, but if I could make it flapping a "yellow" event I think I could make everybody happy. Thanks, Larry Barber

!http, and other http-related questions
by novosirj＠umdnj.edu 19 May '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks, Read the docs and it's not clear to me -- is there a way to specify that http should be down? Similarly, is there some kind of way to say that https should be available on one port, but another port should not be? Would I have to instead use the ports test (undesirable here -- load balanced host and nothing to run an agent on). Thanks for your help in advance. I run 4.2.x but info about 4.3.x if different would be helpful too. - -- - ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - Sr. Systems Programmer |$&| |__| | | |__/ | \| _| |novosirj at umdnj.edu - 973/972.0922 (2-0922) \__/ Univ. of Med. and Dent.|IST/CST-Academic Svcs. - ADMC 450, Newark -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk25m+0ACgkQmb+gadEcsb5JOQCfeTVGEXjaHbN/1yw9l1/O76l0 El0An09VVLMIYq1smIyq1yzB4orJ+Sbj =3ioM -----END PGP SIGNATURE-----

Is it possible to make a custom 'simple view' for non-technical users?
by docuprompt＠gmail.com 19 May '11

19 May '11

My first post- so, of course, it is a question... I'd like to make a simple version of the pages that xymon displays the icons in. A subset that only includes the core items such as cpu, memory, disk and services. What is the best way to do this without affecting the existing pages? It doesn't look like critical host pages will do this, and I want to use that to show critical hosts anyhow. I just loaded xymon and am very impressed. Have used OpenNMS in the past, and it does very well in comparison. It seems to me to be very practically (and nicely) crated :) Many thanks in advance!
