Bogus Dovecot upgraded libs warnings 🔗 link

Hi folks,

Recently I upgraded a Dovecot IMAP host and now Xymon regularly warns  about linked libs that have been upgraded for many of the  "dovecot/imap" processes. When the users log out and the processes  disappear, the warning disappears as well. Obviously, these warning  are bogus. Would anyone happen to know what to add to  /etc/xymon/libs.local.yaml, presumably, to prevent this warning from  occurring?

Old host:
   * Debian 10 (buster)
   * Dovecot 2.3.4.1
   * Xymon client: 4.3.28

New host:
   * Debian 11 (bullseye)
   * Dovecot 2.3.13
   * Xymon client: 4.3.30

Xymon host (in both cases):
   * Debian 11 (bullseye)
   * Xymon server: 4.3.30


Cheers,

Jaap

I think we had the same problems (also Debian) and I guess, this line in our libs.yaml stems from there:

- 'dovecot(\.index|-uidlist|\.list\.index)'

I just compared it to our other servers and this line seems to be unique in our xymon hosts, so I'm pretty sure it was added to fix this problem.

The libs report includes the process ID(s) of the relevant processes in brackets. The libs test pretty much just runs the lsof command and looks for files which are either 'deleted' or 'DEL', so you can do this check for yourself for a particular pid..

lsof -p 12345 | | awk '$4 ~ "DEL|deleted" {print $NF}

..will print a list of filenames you might want to add libs.local.yml

Hi Christoph,

Your solution works! I added /etc/xymon/libs.local.yaml to the client  configuration with the following content:

# local config file for the libs test
---
whitelist:
    *:
      - 'dovecot(\.index|-uidlist|\.list\.index)'


This is different from the existing line in /etc/xymon/libs.yaml:

      - 'dovecot(\.index|-uidlist)'

Thank you very much. My Xymon page is green again!

Cheers,

Jaap

Hi folks,

Christoph was recently so kind as to describe for me the solution  below. However, the question I'd like to ask now is, how does one go  about figuring out that kind of solution?

Thanks,

Jaap
