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

Terabithia RPM support for Amazon Linux
by mburger＠bubbanfriends.org 30 Jun '21

30 Jun '21

Good afternoon. In perusing the Terabithia repository for Xymon(-client) RPMs, I see that there are directories for Amazon Linux 1 and 2, but I do not, yet, see packages in those directories. I was wondering when we might start seeing packages for AWS Linux. Thanks. -- Mike Burger http://www.bubbanfriends.org "It's always suicide-mission this, save-the-planet that.

Problems with 'COMPACT'
by colin.coe＠gmail.com 28 Jun '21

28 Jun '21

Hi all I'm trying to use the 'COMPACT' directive for a few custom tests. My config looks a it like: 1.1.1.1 a_fim # noconn COMPACT:fim=fim_test1|fim_test2|fim_test3|fim_test4 NOCOLUMNS:conn,info,trends 1.1.1.2 b_fim # noconn COMPACT:fim=fim_test1|fim_test2|fim_test3|fim_test4 NOCOLUMNS:conn,info,trends 1.1.1.3 c_fim # noconn COMPACT:fim=fim_test1|fim_test2|fim_test3|fim_test4 NOCOLUMNS:conn,info,trends The problem is that the first compacted test (fim_test1) seems to not get included in the compacting (ie, it shows on the non-green page) and if any of the compacted tests for any host are non-green, every host with the compacted test is shown on the non-green page. Anyone else having this problem or have I configured it wrong? Thanks

Use X-Forwarded-For header for client IP?
by hobbit＠elyograg.org 28 Jun '21

28 Jun '21

I have all my websites behind a reverse proxy.? For those who might be interested, it's haproxy.? I'm using it because it handles all the TLS and can be easily configured to handle DDOS attacks. Is it difficult to get xymon to use the X-Forwarded-For header?? Did some googline and came up empty.? I have some disabled tests, and this is what it says: Disabled?by:?elyograg?@?127.0.0.1 I would like to see the real IP address there.? I've got Xymon 4.3.28 installed from source. Thanks, Shawn

Hosts with multiple names - separate page for all names?

We don't use the NAME tag, but would have to use the strict name in the tag. The problem then is that the status pages then show the strict name and not the colloquial one. Also it seems that the findhost option shows the tag (srict) name, and not the colloquial one as well. I need something that will show both names at the same time.

Hosts with multiple names - separate page for all names?
by john.horne＠plymouth.ac.uk 25 Jun '21

25 Jun '21

Hello, The subject line isn't quite accurate, but I couldn't quite think how to to describe the issue in a few words. From a long time ago I have given our Linux servers colloquial names, but the servers also have more strict names from when they are created. As an example, our 'bb' server (so called because it ran the Big Brother software) is more correctly known as 'cent-8-023'. I cannot remember the strict names for servers, but can the colloquial ones. So our Xymon (4.3.30) hosts.cfg file lists the hosts with their colloquial name, and a CLIENT: option with the strict name and a DESCR: option with the server strict name and its IP address. E.g: 10.11.12.13 bb # CLIENT:cent-8-023 DESCR:"Server: cent-8-023 - 10.11.12.13" All this means that on the Main view page I see the colloquial name, but if I hold the mouse over the host name I then see the description. Great :-) However, other people are always using the servers strict names when reporting things to me, and that means I have to perform some form of lookup of what strict name corresponds to what colloquial name. I could do that simply by running the mouse over all the host names on the Main view page - not very good; takes too long. I could simply keep a text list of server names - a bit too old school even for me! So the question is, is there some way to configure Xymon such that perhaps there is a sub-page of all the same hosts but with their strict and colloquial names being shown? The host entry for the sub-page might then be: 10.11.12.13 bb-cent-8-023 # CLIENT:cent-8-023... The sub-page would only really be used to see both of the servers names (colloquial and strict). I would rather that the host entries did not appear on the Main view status page since that in effect would double the number of hosts being shown. I could do this for the Main view status page as it is at the moment, but it contains enough information already and expanding the host names further I think would make it look a bit cluttered and not what I really want to do. Thanks, John. -- John Horne | Senior Operations Analyst | Technology and Information Services University of Plymouth | Drake Circus | Plymouth | Devon | PL4 8AA | UK ________________________________ [http://www.plymouth.ac.uk/images/email_footer.gif]<http://www.plymouth.ac.uk/worldclass> This email and any files with it are confidential and intended solely for the use of the recipient to whom it is addressed.

Monitoring for process runs too long
by jeremy＠laidman.org 23 Jun '21

23 Jun '21

Robert If the process creates a PID file, and cleans up when done, you could monitor the age of that file, and alert when it's beyond a threshold. One problem with this approach is that it requires a clientlocal.cfg entry to collect the PID file's metadata, and it's only the last Xymon server's clientlocal.cfg that gets used. (By "last" I mean which is listed last in the client's XYMSRV setting.) If the third party happens to have added your Xymon server last, then you might get this to work just fine, but that situation might change in the future if the client is reconfigured to put another Xymon server last.
