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

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

Xymon 4.3.30 Released
by cleaver＠terabithia.org 31 Jul '20

31 Jul '20

Xymon 4.3.30 has been released and is now available for download. 4.3.30 is mostly a bug-fix release, quashing issues stemming from the security fixes in 4.3.29, including improperly-tight restrictions on allowed characters in hostname for browsing along with several other parsing errors. Thanks in particular to Tom Schmidt for his assistance in tracking these down. Xymon should also now be more easily buildable on older GCC versions without the diagnostics pragma available. Xymon 4.3.30 is available from the Xymon SourceForge page at https://sourceforge.net/projects/xymon/ As always, thank you to all who have contributed code, ideas, and features to the project! Regards, Japheth "J.C." Cleaver

PROC monitoring on timed non existence
by josh＠imaginenetworksllc.com 30 Dec '19

30 Dec '19

I have a ps that comes up every 5 minutes and runs. Is there a way to monitor this? I'm wondering if there is a way to have Xymon go yellow if the ps is not seen for 60 minutes, based on the assumption that the client will generate at least one output per hour if it is running as expected.

Config for msgs column - how to play with client-local.cfg and analysis.cfg? How to play with default and specific entries?
by christian.becker＠rhein-zeitung.net 16 Dec '19

16 Dec '19

Hello everybody, i?m writing this to the list because I?m screwed up with my thoughts, probably because I?ve done too much config tests for today?.. Hope I can describe my situation good enough. I?ve configured nearly 120 linux machines (servers) in our Xymon environment, most of them running Ubuntu 14.04/16.04/18.04 LTS or CentOS 6/7. Xymon server is on 4.3.29, clients are on different releases starting at 4.3.17. All of them are configured to write their system logs to /var/log/messages ? that?s working. What I want to achieve: 1. For ALL of them, I want to have the ?msgs? column filled with the data coming from /var/log/messages, so that I can configure alerting, if some keywords occur in /var/log/messages. 2. In addition to that, for SOME of these servers, I want to have application specific logfiles monitored in the ?msgs? column, and I want to monitor those application specific logfiles for keywords too. 3. In further addition to the above, I want to have EACH ?files? column filled with the files that are monitored in the ?msgs? column per server. Actually I?m struggling with config files on my Xymon server, client-local.cfg and analysis.cfg, and there with class-entries, default section and server specific rules. That makes my crazy. My thought was to have a class configured in client-local.cfg which is: [linux] file:/var/log/messages file:/var/log/ntp log:/var/log/messages:10240 ignore MARK For those servers where I want to have additional, application specific logfiles, I have server based entries like this in client-local.cfg (hoping that this ?over-controls? the class entry from above?.): [dvst-1] file:/var/log/messages file:/var/log/ntp file:/data/monitor/checkppi.log log:/data/monitor/checkppi.log:10240 log:/var/log/messages:10240 ignore MARK This section is BELOW the class [linux] section, if that matters? Everytime I did a config change on client-local.cfg I did a restart of Xymon on my xymon server and I had to wait minutes over minutes to see the result. To make the thing complete and to have more confusion, I have these entries in analysis.cfg: Example of a server specific entry: HOST=dvst-1 DISK /data 97 98 PROC "mysqld " PROC "mysqld_safe" PROC "httpd2-prefork" 1 PROC "smbd? PROC "caagentd" LOG /data/monitor/checkppi.log OutOfMemory COLOR=red Finally a DEFAULT section (at the end of the file): DEFAULT # These are the built-in defaults. DISK * 90 95 MEMSWAP 80 90 MEMACT 90 97 FILE /var/log/ntp SIZE>0 FILE /var/log/messages LOG /var/log/messages %(I/O|read).error IGNORE=%(fd0|smbd|read_fd_with_timeout|Connection.reset.by.peer|error\.txt) COLOR=red LOG /var/log/messages %Remounting.filesystem.read-only COLOR=red LOG /var/log/messages There.are.errors.in.the.filesystem COLOR=red The problem is, that I cannot see data from the configured logfiles in the affected ?msgs? columns. For some logfile entries I get parse errors and I don?t know exactly the reason behind this. All of the configured logfiles are present on the affected servers, there they are readable and filled with data. Does anybody have a real good description of the best way to get the ?msgs? column populated with data? Of the ?playing together? and the right order of entries in the config-files? Hope anybody can follow my thoughts ? Regards Christian
