XymonD --merge-clientlocal issues
by tlwilliams4＠vcu.edu 17 Oct '18

We have set up a new 4.3.28 xymon server, and will be migrating hosts to it in the next few weeks. On it I would like to start to use the --merge-clientlocal command. In testing, Windows powershell clients pick up either the individual host section OR the powershell section, it does not merge. Are there subtleties not in the man-pages that people have found to get it to work? (note that the xymond man-page states to use --merge-clientconfig, but that doesn't work either) Could it be the section/host headings, or order? I have: [server1] file:somefile [server2] file:different file [os=powershell] (also tried [class=powershell] and [powershell] alone) xymonlogsend clientversion:2.28:http://url Thanks, Tim Williams

odd "failure" for file exists
by solitaryr＠gmail.com 16 Oct '18

16 Oct '18

Ok...this is weird. I have Xymon triggering when a file (coredump) exists but it only turns red when a new file shows up...it should remain red until the files are cleaned up. After the next update cycle it goes green yet the page shows that it sees the files. Any thoughts on this behavior? I have another "file exists" test that is behaving as expected (at least I think it is). thanks =G=

xymon not warning

Is the status green or yellow? If green, check your analysis.cfg will match this host and limits configured appropriately. If yellow, check the info page for this host to see what alerting you have, and configure alerting in alerts.cfg if needed. If configured OK, check the notifications report.

Linux client with local-config (or bb-memory.sh for linux)
by john.thurston＠alaska.gov 12 Oct '18

12 Oct '18

We run xymon servers the old-school way*: local config of clients with client-side evaluation of thresholds. I run a mashup of ancient BB, newer BBPE, and even newer xymon clients. I'm in need of memory monitoring on a CentOS 7 host. The client I have there (I think it is a BBPE version) doesn't provide it. So I reached back and grabbed a bb-memory.sh from some other system. But it doesn't work cleanly :( For linux, the script captures the output of 'free -m' and then populates variables: FREE_PHYS FREE_ACT FREE_SWAP by grepping lines from the result: Mem + Swap and my version of 'free' (3.3.10) has moved the '+/-' information up into a new column in the 'Mem' line. I don't see a way to adjust the 'free' command to return results in the old format, so I'll need to accommodate the new format in the shell script. Before I go dive in and engineer my own parser, I thought I'd ask here: Does anyone have a bb-memory.sh they'd share with me? Alternatively, I could remove the old client and install something newer. But the last time I tried compiling the client with the 'local-config' option, it didn't work out well. So my second question is: Is there a linux client package that correctly support local-config? * Yeah, I know there are plenty who think this is a terrible idea and can't stand the concept. But I don't own most of the hosts. So I don't want to have them dragging my central code down to them. Nor do I know the business rules which define success or failure. It's up to the owner of the host to set those things. -- Do things because you should, not just because you can.

Error "Fatal signal caught!"
by jkikpole＠cairodurham.org 12 Oct '18

12 Oct '18

For quite some time now, my Xymon server has been showing "Program crashed" and "Fatal signal caught" on the second line of the xymond_alert status page. It shows up as a purple alarm. I haven't been able to figure out what caused it. I've even gone so far as to upgrade the OS, Apache, Xymon, etc. Recently, after those updates I mentioned, it added a purple alarm to xymonlaunch, too. The message is "Program crashed" and "Fatal signal caught!". Any suggestions on how to debug this would be greatly appreciated.

interacting with a modern browser for monitoring
by Scot.Kreienkamp＠la-z-boy.com 12 Oct '18

12 Oct '18

Hi everyone, Does anyone know how or have any experience with scripting a modern browser and possibly interfacing that with Xymon? I have a requirement to monitor our ERP system, and it has to be a login to the app via a modern web browser, which means java, etc. Is there any way that anyone has come across for simulating those calls and replaying them, and interfacing that with Xymon? I've been trying to copy session calls with CURL and not having much success yet. I've also found Selenium but haven't done more than look at the front page of the site yet. Any info about using that would be appreciated too. Thanks for any suggestions.

Hello Damien, I treid your script. When running in testmode it works fine. It is creating /var/lib/xymon/tmp/xymon-hardware.msg But when running as a deamon i am getting /bin/cat: /var/lib/xymon/tmp/xymon-hardware.msg: No such file or directory Any idees?

client change of IP...

This is one reason you might want to run a DNS cache on your Xymon server. Everything gets looked up, every time.

xymon 4.3.28 learned something new today! We have a xymon client - lets call it FRED. FRED has its IP changed and so hosts.cfg is updated with the new IP. BUT the xymon conn test continues to use the previous IP to ping against. It seems (my learning point!) that the conn test does NOT use the contents of hosts.cfg... but the dns resolution for the hostname (or at least primarily). Only when the DNS was updated did xymon then use the new IP for the conn test. Who knew? (Well, not me bit I expect all you probably did! LOL) didds
