will Xymon 4.3.30 handle automatically CPU downgrades?
by Randall Badilla Castro 19 Nov '25

19 Nov '25

Hi people: we use Xymon 4.3.30 and I believe had issues when vms are downgrade on the CPU quantity. For example one vms was 12 CPUs and month ago we re-shape it to 2 CPUs (same RAM). But the realCPU stats sometime show and Y axis of 120%... For example today got red alarm by realCPU on 95% and the graph show a Y axis of 120%. Should we make some adjustments or issue some command to correct this ? Any input will really appreciate it. I don't know if this helps but; this example is running redhat 8.6 on Oracle OCI cloud. cat /etc/*release NAME="Red Hat Enterprise Linux" VERSION="8.6 (Ootpa)" ID="rhel" ID_LIKE="fedora" VERSION_ID="8.6" PLATFORM_ID="platform:el8" PRETTY_NAME="Red Hat Enterprise Linux 8.6 (Ootpa)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:redhat:enterprise_linux:8::baseos" HOME_URL="https://www.redhat.com/" DOCUMENTATION_URL="https://access.redhat.com/documentation/red_hat_enterprise_linux/8/" BUG_REPORT_URL="https://bugzilla.redhat.com/" REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 8" REDHAT_BUGZILLA_PRODUCT_VERSION=8.6 REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux" REDHAT_SUPPORT_PRODUCT_VERSION="8.6" Red Hat Enterprise Linux release 8.6 (Ootpa) Red Hat Enterprise Linux release 8.6 (Ootpa) -- Quedamos atentos a vuestra amable retroalimentación y/u observaciones.

monitor connectivity from Windows powershell host
by hopbyhop.net 22 Sep '25

Hi all. I would check connectivity from a Windows machine (with XymonPSClient installed) do one or a few external host. Just a ping response time would be enough. Anyone has a quick and dirty solution already implemented? Thanks Mario

Issue with xymon-rclient.sh
by Becker Christian 28 Jul '25

28 Jul '25

Hi to the list, working with xymon since 2008, still using it. Now I was in the situation to include a LinuxMint machine (with desktop environment), using Jeremy's xymon-rclient.sh 0.6.1 to monitor this thing. After setting up the ssh-based authentication and waiting a couple of minutes, the data of this LinuxMint machine came up and appeared in Xymon. Other than other machines i'm pulling with xymon-rclient.sh, the CPU state of this machine became red immediately. It seems to me that the Load Average of the LinuxMint machine is interpreted wrong: when looking in Xymon, it tells me a Load Average of 60.00, while looking to the LinuxMint machine, seeing it's Load Average at 0.6. What could be wrong? The LinuxMint machine is running LinuxMint 22.1 with it's lates updates. These are the locales used by the LinuxMint machine: LANG=en_US.UTF-8 LANGUAGE=en_US LC_CTYPE="en_US.UTF-8" LC_NUMERIC=de_DE.UTF-8 LC_TIME=de_DE.UTF-8 LC_COLLATE="en_US.UTF-8" LC_MONETARY=de_DE.UTF-8 LC_MESSAGES="en_US.UTF-8" LC_PAPER=de_DE.UTF-8 LC_NAME=de_DE.UTF-8 LC_ADDRESS=de_DE.UTF-8 LC_TELEPHONE=de_DE.UTF-8 LC_MEASUREMENT=de_DE.UTF-8 LC_IDENTIFICATION=de_DE.UTF-8 LC_ALL= Yes, they are mixed.... We've a few other linux client machines running "non-server-linuxes" (i.e. RaspberryPi running Raspberry PI OS) which are reporting fine using xymon-rclient.sh. Regards Christian

https "Misdirected request" monitoring after target ubuntu 8.7 update
by betsys＠well.com 22 Jul '25

22 Jul '25

We have an https test which started erroring when the target host auto-updated from ubuntu 8.6 to 8.7 Anyone seeing anything like this? Apache version hasn't changed , 2.4.58, although packages are re-installed with 8.7 versions Searching for "Misdirected request" brings up issues with multi-name certs but target cert is just for the one hostname, no SAN no wildcard. Tried the various things like httpsc, httpsm, httpsh, no joy. If I limit to http the test is green . I can wget the https page from the xymon host The SSL cert test has stayed green uninterrupted. Ran the site past Qualys SSL test (external IP) and testssl (internal) with nothing much interesting.

Windows PowerShell client not starting
by Jaime Kikpole 31 Mar '25

31 Mar '25

I'm setting up 4 new VMs running Windows Server 2022 Datacenter. Using the same technique that I've used to set up the PowerShell version of the Xymon client over the last few years, I copied the files into C:\Program Files\Xymon\ and then run ".\xymonclient.ps1 install" and ".\xymonclient.ps1 run". For the first time in my experience, this isn't working. Is using the PowerShell client still recommended for monitoring Windows systems? Is it compatible with Windows Server 2022? Here is the text I get when I try to start the service from a PowerShell window run as an administrator. PS C:\Program Files\Xymon> .\xymonclient.ps1 start Security warning Run only scripts that you trust. While scripts from the internet can be useful, this script can potentially harm your computer. If you trust this script, use the Unblock-File cmdlet to allow the script to run without this warning message. Do you want to run C:\Program Files\Xymon\xymonclient.ps1? [D] Do not run [R] Run once [S] Suspend [?] Help (default is "D"): r start-service : Failed to start service 'XymonPSClient (XymonPSClient)'.

SSL stuck on purple
by Jaime Kikpole 26 Mar '25

26 Mar '25

I have a Xymon install that was monitoring (among other things) an HTTPS site. That site moved to a new IP and while I did update the public DNS records it was a few days (or maybe two weeks?) before I remembered to update the internal DNS records. By then, Xymon was reporting red for HTTPS and purple for SSL. I've corrected the DNS records and the VM running Xymon is resolving it correctly, but now it is still showing the same red and purple alerts. Every now and then, they'll switch to green for a little while and then back to red and purple. I'm not sure why. Xymon's web interface shows that the certificate is valid for more than 2 months. So that isn't it. I've restarted the Xymon server process and even the whole OS, but this issue remains. Any ideas on what I could check? Thanks, Jaime

Query for first occurance in xymon
by Becker Christian 19 Mar '25

19 Mar '25

Hi to the list, i'm working with xymon since 2008 and i thought i can help myself out whereever it's necessary. Now we are in the situation that we need kind of a query to show the first occurance of a system configured in xymon (currently 956 monitored devices and services). Looking through the man-pages i didn't find any helpful hint, neither using command-line nor using any xymon report tool. Due to the fact that we have different types of configured systems (linux servers configured as xymon client, linux servers that are pulled using xymon rclient, windows systems running either BBWin or PowerShell client) it's hard to find a way to get such a list. Looking through every single monitored system, then looking in any graph history to see if this is beginning within the last 576 days, this is not an option for us. Further i'm aware of the fact, that -for many systems- this begins with the xymon server's rollout. Does anyone of you have an idea or a hint? Regards from Germany Christian

Weird issue with Trands on a small amount of servers

Hi all, On a couple of servers (maybe more) I get the following when trying to access the "trends" column Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.
