assistance for auto start of xymon in Rocky 9
by David Smith 23 Jan '25

23 Jan '25

Hi I am looking for some clues to autostart xymon in Rocky9 I copied my method from a Centos 7 box which has been running successfully for quite a number of years I made a xymonlaunch.service file which I placed in /etc/system/system, contents below # xymonlaunch.service # systemd file for Fedora 18 and up, or RHEL 7 and up [Unit] Description=Xymon systems and network monitor Documentation=man:xymon(7) man:xymonlaunch(8) man:xymon(1) After=network.target [Install] # Compatibility with "xymon" and "xymon-client" Alias=xymon.service Alias=xymon-client.service WantedBy=multi-user.target [Service] #EnvironmentFile=/etc/sysconfig/xymonlaunch User=xymon # We wrap in xymoncmd to eliminate the need for the bulk of the old init script ExecStart=/opt/BB/bbsw/server/bin/xymoncmd /opt/BB/bbsw/server/bin/xymonlaunch --no-daemon $XYMONLAUNCHOPTS Type=simple # Kill xymonlaunch, but don't send kills to the underlying procs, since they # might be doing important things (like writing checkpoints and flushing caches) KillMode=process # SendSIGHUP=yes SendSIGKILL=no I then did systemctl enable xymonlaunch.service, and this made 2 symbolic links in the same directory one named xymon.service and one named xymon-client.service What is happening on Rocky9 is that on the server is being started, the client part does not start Any ideas what may be awry? The same method worked/works without issue on Centos 7 Any help, guidance, clues would be much appreciated. I know that I would be able to cobble something together to stick into rc.local, but the powers that be up above would rather I did it using the method that uses systemctl Best regards David Renfrewshire Council Website -http://www.renfrewshire.gov.uk This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Hi all Has anyone got DEVMON working on RHEL9? I'm working with https://github.com/bonomani/devmon but can't get any SNMP polling working. The current server is RHEL6 and working (mostly) fine but I need to get off RHEL6/7. Thanks

[patch] enable/disable page pagepath cookie filtering
by Christoph Zechner 29 Aug '24

29 Aug '24

Hi, we noticed a problem when trying to access the "enable/disable" page from other pages than the main page, because it would not load all available hosts, but only a small selection. The "enable/disable" page requested with GET uses the "pagepath" cookie to set a filter. Currently this cookie is set to "" on main view, and to the current path and sub-pages, but it is not cleared when accessing the "non-green view" or "critical systems", which it should in our opinion. Also we reset the cookie on the enable/disable page, so the first request will return the filtered page but following requests will not. As filtering is done via a POST one could also reset the pagepath cookie only in response to such requests as an alternative. Please find attached a patch to fix this problem. Best regards Christoph Zechner

cannot seem to add a lot of hosts
by David Smith 28 Aug '24

28 Aug '24

Hi I have got a new install of Xymon 4.3.30 onto Rocky 9 I have got a pre existing install of Xymon 4.3.30 on Centos 7 I naively thought once I had configured everything, that I could copy the whole hosts file from my pre existing install onto the new one, and job would be a good un. BTW this is the method I had used for loads of OS upgrades in the past and it always worked If I do that, all I get is the status for the server, and all the new hosts subpages etc just show as text but no test data for conn, cpu etc. I made the file waaaay smaller, and it still did the same I started from scratch and added 2 hosts and they started populating test data. I augmented that hosts file with just 20 hosts and it then doesn’t do anything again. Any ideas where I should look for issue?

XymonPSClient local address binding?
by Jeremy Laidman 16 Aug '24

16 Aug '24

Hi Can anyone tell me if there's a way to have XymonPSClient bind to a specific IP address (or NIC) when connecting to the Xymon server? I'm having the client installed onto some dual-homed hosts, where the NIC with the default route is used for web services and a secondary NIC is used for management traffic. I need the Xymon client to use the management NIC IP address so that it routes via the management traffic path. I'd rather not add a static route onto the host. Cheers Jeremy

Re: Mailing list moves to new server

But did you also mean that the archiving / web access thereto isn't functional for new messages posted to the mailing list? I was going to share a link to my delayyellow / delayred post with a colleague, but I can't find it, or anything, in the archive on the new server. N.B. I'm not complaining, just looking to better understand. Thank you for all that you do. :-) -- Grant. . . . unix || die

Re: xymond_alert errors when hosts.cfg uses directory includes
by Jeremy Laidman 13 Aug '24

13 Aug '24

John Very belatedly, here is a possible solution to this problem. I managed to trigger this situation recently. I decided to rename a host using "xymon 127.1 'rename host1 host2'" and after that, my alert.log showed the log message containing "*... which is not yet defined; some alerts may not immediately fire*" - the same as you. The old hostname was specified in the log message. The cause appears to have been that the old hostname was stuck in the alert.ckp checkpoint file, while not in hosts.cfg, which xymond_alert didn't like. After dropping the old hostname using "xymon 127.1 'drop host1'" the log messages stopped. My guess is that I didn't wait long enough after renaming the host in hosts.cfg, and when I did the rename, xymond_alert hadn't picked up the change in hostname, and re-added the old hostname.

Need some help with delayyellow / delayred
by Grant Taylor 12 Aug '24

12 Aug '24

Hi, I need some help understanding delayyellow and delayred in Xymon 4.3.30 compiled from source (not distro). I've got some equipment that I'm pinging (conn) and checking web (http) on BMCs (Dell iDRAC and Oracle ILOM) and am having a LOT of trouble with very short lived failures. As in fails a test and then the xymonnet (?) re-tries succeed in the next minute. So I've tried enabling delayyellow and delayred, first with 5 minutes and then with 10 minutes. But I'm still seeing color changes and receiving email notifications. My hosts.cfg entries look like this: 192.0.2.1 test-client-ilom # NAME:Test-Client-ILOM ssh delayred=conn:10,ssh:10 delayyellow=conn:10,ssh:10 These are place holders, but they are find & replace type place holders. Am I incorrect in thinking that delayyellow / delayred will cause the test results for the delay value to be ignored /before/ changing color? I suppose that I can change from delayyellow / delayred in hosts.cfg and go to their counterpart in the alerts.cfg file and not send the email(s). But I'd rather the page not change colors as we keep a screen open to it and I'd really rather it not false-yellow / false-red to immediately change back to green < 5 minutes later. I'm sure that I'm missing something and am hoping that someone will help me figure things out and learn. Thank you and have a good day. -- Grant. . . . unix || die

best sources for xymon rebuild: still 4.3.30 Sourceforge release?
by hopbyhop.net 12 Aug '24

12 Aug '24

Hello all. I have to recompile xymon after a server OS upgrade. I was on 4.3.30 release but it's really old. I read about a planned maintenance release (before 4.4) a while ago. But on sourceforge there is only a 4.3.31 branch with two commits dated 2019. Any advice? Thanks Mario
