Xymon 4.3.30-1 memory issues and core dumps
by Carl.Melgaard＠STAB.RM.DK 15 Dec '20

15 Dec '20

Hi, After running for 5 hrs on my new installation on a RH 7.9, xymond has already allocated 11.5GB of memory... Last night it core-dumped multiple times, and threw "Cannot allocate memory" in multiple xymon logfiles, ala "newstrbuffer: Attempt to allocate failed (initialsize=1009956863): Cannot allocate memory". Monitoring 1900 hosts currently - on my primary system I do this with only 4 GB of memory with no issues. Any idea where I should start to look - it's a terabithia installation. Heres a couple of the core-dumps gdb'ed: Reading symbols from /usr/libexec/xymon/xymongen...Reading symbols from /usr/lib/debug/usr/libexec/xymon/xymongen.debug...done. done. [New LWP 10035] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".

Where do I start? Regards, Carl Melgaard

??? Hi everyone, ?????? I have a request for a new feature: On the hosts,cfg page, there should be a place to the right of the FQDN for a description field. This field should show up on the main xymon page. Example: ?????? IP????????????????????? FQDN Description 208.145.18.16 ? frank.cronomagic.biz??? for_my_machine?? # NOCOLUMNS:files,inode,info And this should display on the main page. -- sysadm cronomagic.com e-mail ve2cii at canasoft.net POWERED BY LINUX

Order of values in analysis.cfg
by christian.becker＠rhein-zeitung.net 14 Dec '20

14 Dec '20

Hello to the list, this is probably the 50st question about this..... Can anybody guide me to understand, how individual machine thresholds, default thresholds and class thresholds are interpreted in analysis.cfg for different servers and in which order? Let me say this is my analysis.cfg (this is not my working analysis.cfg, it's shown here just to ask my question): # Drop windows servers below here CLASS=win32 MEMACT 85 90 MEMACT 85 90 MEMSWAP 85 90 HOST=WINDOWS-1 MEMACT 97 98 # Drop powershell configured servers below here CLASS=powershell MEMACT 90 95 MEMACT 90 95 MEMSWAP 90 95 HOST=WINDOWS-2 MEMACT 90 92 # Drop linux servers below here CLASS=linux PROC %(syslogd|syslog-ng|rsyslogd) PROC sshd MEMACT 80 85 MEMACT 80 85 MEMSWAP 80 85 HOST=LINUX-1 MEMACT 85 90 # Default values DEFAULT DISK * 90 95 MEMSWAP 80 90 MEMACT 90 95 I have difficulties to understand, how the values would be applied. Is it that way, that it looks to the class of a host and applies the values of the class first, then the rule per hostname, and then the default? Or does it stop at the first match? Regards, greetings from Germany Christian

findhost + enadis not working after in-place upgrade
by Carl.Melgaard＠STAB.RM.DK 09 Dec '20

09 Dec '20

Hi, Where should I look to find out why findhost + enadis GUI's doesn't work at all - findhost returns no hits what so ever and enadis boxes aren't populated with servers at all... (Xymon 4.3.30-1.el7.terabithia). Looked thru the logs, but nothing seems out of order? Regards, Carl

Monitoring folder size, without saveing the whole folder structure
by hobbit＠weiser.dk 04 Dec '20

04 Dec '20

Hi, I have a backup folder which I monitor the folder size of. I do that by using the DIR configuration and a TRACK tag, which is working fine. But every time the client reports in it includes the whole folder structure under the folder I monitor which is big, so the "Client data" file is big and take up a lot space on the server. So what is the best way to avoid that? I have a couple of suggestions, but others are mostly welcome: 1. Set a cron job to delete the files when they are certain age. 2. Maybe some configuration on the DIR command which stop it from sending the sub folders. 3. create a custom script which send the size of the folder I want to monitor. Thanks, Kim

Running a custom test on multiple clients.
by tlwilliams4＠vcu.edu 04 Dec '20

On the Windows PSXymon or (shudder) BBWin client, you can run an external script by specifying it in the client-config file. Client can download from a central repository using URL or BB: (from Xymon server) link to run every scan or on slow scan. Therefore, changes to script are immediately distributed. The script can write an output file to TMP folder and that is picked up and displayed on Xymon console (name of file becomes name of column). As Windows clients were built to mimic the Linux client, I would assume there is a mechanism there as well. *Timothy L.

Running a custom test on multiple clients.
by gabby.gibbons＠yahoo.com 04 Dec '20

04 Dec '20

Hello,?I am trying to figure out if there's a way to write a custom test on the xymon server and then run that test on each client as the client. I am aware of the ability to write a test on the server and then use XYMONGREP to run a test on each machine as the server, but the problem with that is, as far as I can tell, you can only run unauthenticated checks from the outside of the system. Say, for example, I want to monitor a log file using xymon on each client. If I were able to run the check on each system itself as the authenticated xymon user I could do that easily, but I wouldn't be able to view that file from the outside with another computer without first authenticating. Right now my solution is to simply copy all of the custom tests I have to each monitored machine. This works, but the problem is that it's so decentralized. Every time I make a simple change to a script or want to add a new custom script I have to go to every single machine and make the same change. Being able to centralize this somewhat and have the clients all read from one source would make managing custom tests much much easier. Is this possible to do?

Migrating to new server + Xymon version - want to preserve data
by Carl.Melgaard＠STAB.RM.DK 01 Dec '20

Hi, Is it possible to copy over data from old xymon server to a new xymon server? And if so, what data do I need to copy to preserve all historic data (graphs, alerts etc.)? Regards, Carl Melgaard
