I am very interested in your integration efforts. How do you select what is going to be inserted in the ELK stack? All status messages that Xymon receives? And could you provide an example of the xymond_channel block in you task.cfg and the capture.sh? Tasks.cfg probably is something like: [es] ... CMD xymond_channel --channel=status /home/xymon/server/ext/capture.sh ... And the capture.sh contains some curl script to the ELK stack? Regards, Peter 2016-12-14 18:15 GMT+01:00 OUTTERYCK Francois <francois.outteryck at soprasteria.com<mailto:francois.outteryck at soprasteria.com>>: Hello, I just do a small work with Xymon in order to send status data to Elasticsearch. And with Kibana reporting is easy. How it work ? Simple : With capture of status message (xymond_channel --channel=status /home/xymon/server/ext/capture.sh ) script encode status message in json and send as document in elasticSearch. Example of Mapping document status in elasticsearch : "status"=> array( "properties"=>array( "ServerName"=> array("type"=> "string"), "Type"=> array("type"=> "string"), "Status"=> array("type"=> "string"), "LastChange"=> array("type"=> "date","format"=> "strict_date_optional_time"), "LogTime"=> array("type"=> "date","format"=> "strict_date_optional_time"), "ValidTime"=> array("type"=> "date","format"=> "strict_date_optional_time"), "AckTime"=> array("type"=> "date","format"=> "strict_date_optional_time"), "DisableTime"=> array("type"=> "date","format"=> "strict_date_optional_time"), "Sender"=> array("type"=> "string"), "DisableMSg"=> array("type"=> "string"), "Message"=> array("type"=> "string") ) ) All is done with a 130 lines script. So simple to integrate in existing environment and so powerfull usage of Xymon/elasticsearch/Kibana For those who don’t know kibana : https://www.elastic.co/products/kibana [cid:image001.png at 01D25EA3.F74489F0] _______________________________________________ Xymon mailing list Xymon at xymon.com<mailto:Xymon at xymon.com> http://lists.xymon.com/mailman/listinfo/xymon

Terabithia or compile
by ralphmitchell＠gmail.com 16 Mar '22

16 Mar '22

I downloaded the source rpm and installed it. The spec file for building the RPMs contains this: %if %{without trunk} %if 0%{?rhel} <= 7 Requires: ntp %endif %endif So, yeah, it builds into the binary RPMs the requirement to pull in ntp. I'm not sure if that can be made into a conditional, to require ntp OR chrony.

random errors with imaps/pop3s servers offering TLS 1.3
by lolo＠troll.free.org 10 Aug '21

10 Aug '21

Hi, I have found an issue when trying to monitor imaps and pop3s server offering TLS1.3 . My xymon server configuration: # freebsd-version -u 12.0-RELEASE-p5 # openssl version OpenSSL 1.1.1a-freebsd 20 Nov 2018 standard freebsd xymon-server pkg : # pkg info xymon-server-4.3.28 xymon-server-4.3.28 Name : xymon-server Version : 4.3.28 Installed on : Fri Feb 22 14:19:11 2019 CET Origin : net-mgmt/xymon-server Architecture : FreeBSD:12:amd64 Prefix : /usr/local Categories : net-mgmt www Licenses : GPLv2 Maintainer : feld at FreeBSD.org WWW : http://xymon.sourceforge.net/ Comment : System for monitoring servers and networks Options : DEBUG : off LDAP : off NETSNMP : off Shared Libs required: libcares.so.2 libpng16.so.16 libpcre.so.1 librrd.so.8 Annotations : FreeBSD_version: 1200086 cpe : cpe:2.3:a:xymon:xymon:4.3.28:::::freebsd12:x64 repo_type : binary repository : FreeBSD Flat size : 26.5MiB ... # ldd /usr/local/www/xymon/server/bin/xymonnet /usr/local/www/xymon/server/bin/xymonnet: libcares.so.2 => /usr/local/lib/libcares.so.2 (0x80027c000) libssl.so.111 => /usr/lib/libssl.so.111 (0x800297000) libcrypto.so.111 => /lib/libcrypto.so.111 (0x80032c000) libpcre.so.1 => /usr/local/lib/libpcre.so.1 (0x800619000) libc.so.7 => /lib/libc.so.7 (0x8006bd000) libthr.so.3 => /lib/libthr.so.3 (0x800ab0000) When trying to monitor a pop3s or imaps server offering tls 1.3, I got random errors: WARNING: Flapping status Service imaps on xxx is not OK : Unexpected service response If I monitor the same services on an other server not offering tls 1.3, all is fine. Both servers where running dovecot. I wrote an extension in perl using IO::Socket::SSL (and the same local openssl) to monitor the server offerng tls 1.3 and all is fine with it. For some strange reason, I can monitor a https web servers (running nginx or apache) offering TLS 1.3 without this issue but not imaps/pop3s. It looks like the https test is different from other ssl/tls tests and does not have the TLS 1.3 issue Regards, -- Laurent Frigault | Free.org - BookMyName.com - ONLINE SAS - Registar ID 74

Monitoring for process runs too long
by robert.herron＠gmail.com 23 Jun '21

23 Jun '21

I need pointers to documentation or how-to for monitoring via the Client Data server-side. I have a server managed by a third-party. Fortunately, this vendor uses Xymon to monitor it. I cannot add custom EXT scripts to it. The vendor did add my Xymon server to the xymonclient.cfg?s XYMSERVERS parameter so I can set custom thresholds in my analysis.cfg. So, the server had a process that hung and started causing problems. I would like to leverage a Client Data on my server to monitor and alert for this process. Thanks. -- Robert Herron robert.herron at gmail.com

proper upgrade method from 4.3.27 to 4.3.30
by kspringer＠innovateteam.com 01 Jun '21

01 Jun '21

One of my Xymon servers is running Ubuntu v16.04 and Xymon Server v4.3.27 I was gonna build a brand new VM and install the Xymon v4.3.30 and go through all the config edits, but if I can just upgrade Xymon instead that will save me a lot of time, but I'm unclear on the correct method.? I'd like all the configs and paths to stay intact. Is it as simple as unzipping the 4.3.30.tar.gz and running ./configure ? I will of course be snapshoting my server prior to trying this, but I thought I'd ask if anyone has attempted this and run into any issues they could share. -- Kris Springer

xymonnet additional capability -- pause
by hobbit＠elyograg.org 30 May '21

30 May '21

Over ten years ago, I asked on this list how I could get rid of the "incorrect pipelining message" logged by postfix every time the smtp, smtps, or submission tests are done. https://lists.xymon.com/oldarchive/2010/11/msg00207.html The fix that I claim worked (multiple send commands) was for a job I had at the time. Now I am have a personal mail server (that also runs xymon) and that fix I mentioned so long ago is not working. I tweaked the code to allow a "pause" action in protocols.cfg and after modifying protocols.cfg to utilize it, I have eliminated the "incorrect command pipelining" message in mail.log. Here's the patch: --- xymon-4.3.28/lib/netservices.c 2017-01-05 19:00:06.000000000 -0700 +++ pause-xymon-4.3.28/lib/netservices.c 2021-05-29 12:51:09.717461323 -0600 @@ -259,6 +259,10 @@ } } } + else if (strncmp(l, "pause ", 6) == 0) { + int pausetime = atoi(skipwhitespace(l+5)); + sleep(pausetime); + } } if (fd) stackfclose(fd); Here's the new definitions I created in protocols.cfg: [smtp] pause 2 send "ehlo xymonnet.localdomain\r\n" pause 2 send "mail\r\n" pause 2 send "quit\r\n" expect "220" options banner port 25 [smtps] pause 2 send "ehlo xymonnet.localdomain\r\n" pause 2 send "mail\r\n" pause 2 send "quit\r\n" expect "220" options ssl,banner # No default port-number assignment for smtps - nonstandard according to IANA [submission|msa] pause 2 send "ehlo xymonnet.localdomain\r\n" pause 2 send "mail\r\n" pause 2 send "quit\r\n" expect "220" options banner port 587 And this is now what I see in mail.log (testing smtps and submission: May 29 13:51:15 bilbo postfix/submission/smtpd[16324]: connect from bilbo.elyograg.org[172.31.8.104] May 29 13:51:15 bilbo postfix/submission/smtpd[16324]: disconnect from bilbo.elyograg.org[172.31.8.104] quit=1 commands=1 May 29 13:51:15 bilbo postfix/smtps/smtpd[16325]: connect from bilbo.elyograg.org[172.31.8.104] May 29 13:51:15 bilbo postfix/smtps/smtpd[16325]: disconnect from bilbo.elyograg.org[172.31.8.104] quit=1 commands=1 Interesting thing here is that it's not actually pausing. Which probably means that I implemented it incorrectly. My training on C is ancient and I'm very rusty. But even though it doesn't pause, the error is gone, simply because each smtp command is now sent in a separate packet, which appears to *sometimes* be enough "delay" for postfix to not complain about pipelining. What happens now is occasionally I will get a yellow status on smtps with the xymon UI saying "Service smtps on bilbo.elyograg.org is not OK : Unexpected service response". So I think what I will do before submitting a patch is implement a "null" action (which will do nothing) as well as a "pause" action, and get some help from the real C developers here for making "pause" behave as advertised. Can somebody point me to some instructions on properly creating and submitting a patch? Also, if I could get some info on any other files I need to modify (man pages, readme files, etc), I would really appreciate it. Thanks, Shawn

PS Client in "local mode"?
by john.thurston＠alaska.gov 28 May '21

28 May '21

The old BB and Xymon clients for Windows rely on ancient libraries, so I'm looking at my options. It appears to me that the Powershell client is the only thing out there. Is there the correct location for the most recent? https://github.com/svn2github/xymon And can anyone tell me if it can be run in "local config mode", wherein the evaluation of red/green occurs on the host (rather than the server)? -- Do things because you should, not just because you can.
