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

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

Too much data for svcstatus.sh?
by mburger＠bubbanfriends.org 12 Oct '20

12 Oct '20

Good morning. Running Xymon 4.3.30, compiled from source tarball, on a RHEL 6.10 server. This morning, I encountered an interesting issue. I have a monitored system that has 197 discrete filesystems/mounts. When I attempt to enter this server's "Trends" section, I receive an internal server error (500). My httpd error log shows this when I attempt to access the trends link for the server in question: [Thu May 21 11:29:41 2020] [error] [client 10.40.24.55] Premature end of script headers: svcstatus.sh, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] *** glibc detected *** /apps/xymon/server/bin/svcstatus.cgi: realloc(): invalid next size: 0x0000000000de7dd0 ***, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x408a4f], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x403453], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x404bb7], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x4022c9], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] 00400000-0043c000 r-xp 00000000 fd:08 24906 /apps/xymon/server/bin/svcstatus.cgi, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] 0063c000-0063e000 rw-p 0003c000 fd:08 24906 /apps/xymon/server/bin/svcstatus.cgi, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html This does not happen for any other monitored system in my environment.

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

Question on controlling alerts.
by jacob＠shadowsoft.com 01 Jul '20

01 Jul '20

If I have multiple files being checked or multiple services being checked how do I control alerts for a specific item.? Such as two processes:? Process1 and Process2.? One of them goes red.? How do I send an alert based on the correct item.? Is it indexed or something.? I have looked in forums and email history for last several years but have not found how to do this? Thanks Paul Jordan

Proxy HTTPS requests don't use CONNECT
by canne74＠gmail.com 29 Jun '20

29 Jun '20

Hi, I am trying to setup some squid proxy checks with Xymon 4.3.17 (or 4.3.28: I have 2 servers in manual failover). * I added the `--bb-proxy-syntax` flag to the [xymonnet] section of tasks.cfg * I added a line with "1.1.1.1 proxy # testip http://1.1.1.1:3128/https://github.com/" to hosts.cfg * I spun up a tcpdump, and I see requests coming as "GET https://github.com/ HTTP/1.1" instead of the expected "CONNECT github.com:443" The error page states: > https://www.github.com/ - Not Implemented > > If I use "https" as the protocol for the proxy part, I get > https://github.com/ - SSL error > and Unspecified SSL error in SSL_connect to 30755/tcp on host 1.1.1.1: > error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol > in the log (of course I cannot read the request through tcpdump) Is there anything I am missing? Thank you -- Nicola

IPv6 and state of developement
by Krinetzki＠itc.rwth-aachen.de 24 Jun '20

24 Jun '20

Dear all, Our university is now moving from IPv4 to IPv6 and we want to continue using Xymon as a monitoring tool, but we are facing some difficulties. I have now compiled the latest archive version [r8119] from the 4.x-master. The compilation process ran without problems, but there were problems when starting the xymon-client and the xymon-server because of wrongly set variables. Fortunately this was solved, now client and server are running, but neither the server nor the client get correct monitoring data. With an IPv6 only Xymon server the client reports the following in the logs: 2020-06-23 10:07:20.222067 Whoops ! Failed to send message (timeout) 2020-06-23 10:07:20.222133 -> 2020-06-23 10:07:20.222137 -> Recipient '2a00:8a60:1:9304::1', timeout -2 2020-06-23 10:07:20.222141 -> 1st line: 'extcombo 1100 3484' The IP of the Client is 2a00:8a60:1:9304::1:5. So imho there is missing a block. Even the ping Tests doesn't work. Any suggestions, where to look? The IPv6 addresses are in the normal IPv6 format, in the config file and in the hosts.cfg. Maybe someone can give me a hint. The next question: Is there any developing at the moment or should we switch to a better maintained monitoring system?

HTTPS monitoring, with different IP
by mailinglists＠websitemanagers.com.au 21 Jun '20

21 Jun '20

I have a strange setup, my web server is behind a 1:1 NAT, and xymon is also behind the same router. The router doesn't support network pinning (ie, go out, and then translate on the way back in again), so the network test simply timeout. I've found a "solution" which is to configure xymon to talk to the internal IP address instead of the external one, but instead of changing the DNS or using /etc/hosts file, I want to keep this change to the xymon config. So currently I have this: 0.0.0.0??? ??? www.mysite.com.au??? ??? ??? # noconn httpstatus;https://mysite.com.au=10.0.0.23/;2.. This solves the problem for the http column (I get a green dot, and everything is OK), but I get a red dot for sslcert because xymon is looking at the wrong SSL certificate (not using SNI correctly). I'm using the xymon package from debian version 4.3.28-5+deb10u1 in case that is relevant. Is there a solution to have xymon correctly monitor the SSL certificate when using a different IP address? Regards, Adam
