[Xymon] xymon disk not alerting at 100%, need another set of eyes

[Scot Kreienkamp]

It’s not the partition the client is on, and it’s been that way for days.

So a bit more troubleshooting, I moved all the files out of analysis.d so the only analysis config is the default included from the install and restarted xymon.

[root at monvxymon analysis.d]# /usr/libexec/xymon/xymond_client --dump-config --config=etc/analysis.cfg   ; echo Done
UP 3600 -1 (line: 365)
LOAD 5.00 10.00 (line: 366)
DISK * 90% 95% 0 -1 red (line: 367)
INODE * 70% 90% 0 -1 red (line: 368)
MEMREAL 100 101 (line: 369)
MEMSWAP 50 80 (line: 370)
MEMACT 90 97 (line: 371)
Done


Then I restarted my client to force it to report in.  The disk test is still green with the /boot partition at 100% full!  All my windows clients are working, but NONE of my Linux clients with disk full conditions are working.

Something is definitely broken!

JC, any ideas?

Hi Scott,

What may have happened is that the disk filled up quicker than the client could send the alert.
If the client is on the same disk that is full.  That's caught me a few times.

So I had another thought, I copied the class statement to another file so it’s now first in the list and last in the list, and my disk test is still green.  Is the class match broken?

I’m on 4.3.27-1 from Terabithia.

Thanks!

After re-reading I can see how that may not be totally clear.  By alerting, I mean that the disk test is still green, even though a partition is at 100%full.




I found two hosts that weren’t alerting on disk full condition and started digging into the problem further.  As I understand it, xymon matches the first entry from analysis config files.  So I dumped the analysis config for disks:

Client line:
[collector:]
client corpvskreienl,na,lzb,hq.linux linux

[root at monvxymon hosts.d]# /usr/libexec/xymon/xymond_client --dump-config --config=etc/analysis.cfg |grep -i ^disk

I can’t find any lines above where the hostname matches, it’s on page Infrastructure/Miscellaneous so none of the page statements match, so it should match on the class.  Or the very last line is the system default which should apply if nothing else.  My server is sitting at 100%full on one partition so it SHOULD be alerting.

Thanks for any help.
