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

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.

Baffled by absence of "ssh" in certain "hosts.cfg" entries, yet SSH tests are run
by earle＠isolar.DynDNS.ORG 30 Sep '21

30 Sep '21

I'm setting up a new instance of Xymon 4.3.30 on a RHEL 7.9 system and something simple has me absolutely baffled. -- [root at adm2 hosts.d]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.9 (Maipo) [root at adm2 hosts.d]# rpm -q xymon xymon-4.3.30-1.el7.x86_64 -- In the setup there are a couple of VMware vCenters and several VMware ESXi hosts. The vCenter(s) have SSH and Web server access, but the ESXi hosts have had their SSH servers disabled and they only run the Web services. A greatly oversimplified version of my "/etc/xymon/hosts.d/localhosts.cfg" file is as follows: -- [root at adm2 hosts.d]# grep https localhosts.cfg 192.168.1.1 vcenter01 # ssh https://vcenter01=192.168.1.1/ 192.168.1.100 esxi-1 # https://esxi-1=192.168.1.100/ 192.168.1.101 esxi-2 # https://esxi-2=192.168.1.101/ -- After putting in these entries, the vCenter shows up fine in the Web interface but the ESXi hosts all show up with an "ssh" column - and red entries for all! About 30 minutes later, they've turned to purple. As you can see, I didn't put "ssh" into the (local)hosts.cfg file entries for the ESXi hosts; so why are they showing up as red alerts? It's like as if the "https" test is implicitly causing an "ssh" test to be run, even if I didn't ask for it. Color me baffled. If I don't put "ssh" into the hosts.cfg entry, why is it running an "ssh" test? Any clues? I'm sure I could probably run "xymon 127.0.0.1 'drop <host> ssh'" for all of them, but I'd rather know why this is happening. Thanks in advance for any help. - Greg

Ian [disclaimer: I don't use the smtp check] I'm wondering if the "connect timeout" relates not to the TCP connection but the SMTP conversation. I would do a packet capture during the interaction between xymonnet and the mail server, and see if it closely matches your telnet interaction, or deviates. The smtp check is defined in protocols.cfg [smtp] send "mail\r\nquit\r\n" expect "220" options banner port 25 This expects a 220 in the response after the mail\r\nquit\r\n is sent: '*It will then expect a response beginning with "220".*' (my emphasis on the word "then") Your interaction shows 221 instead of 220, after the mail/quit strings. But if this is the problem, then protocols.cfg has been wrong for many, many years. I suspect (contrary to what I infer from the man page) that "expect" looks in the strings for the whole interaction, not just the ones after the "send" string is sent. In which case, the protocols.cfg entry for smtp should work fine. However, you might like to test removing the "expect" or altering to look for 221 instead of 220.

Ian I believe the postfix warning is because there's a "mail" command before a "helo" or "ehlo" command. Pipelining is when Postfix checks to see that the mail client is waiting for the response to one command, before sending the next command, rather than just sending a "pipeline" of commands without checking the results of each. Spamming robots do this kind of thing. You can either modify the postfix configuration (see reject_unauth_pipelining), or adjust the [smtp] protocol to not start sending a mail message. I'd suggest sending "ehlo xymonnet\r\nquit\r\n". What triggers the smtp check is: a) you have "smtp" on the host's line in hosts.cfg, and b) you have xymonnet being launched every 5 minutes, which reads hosts.cfg, sees "smtp" and looks up the [smtp] section in protocols.cfg When there's a test failure, xymonnet-again runs every minute and does a rapid re-check of any failed tests. So a test that goes red can go green again a minute later. In fact, xymonnet and xymonnet-again don't seem to be synchronised at all, so I guess it's possible for xymonnet to run immediately after xymonnet has finished.
