[cloud::azure::management::monitor::plugin] - mode=(get-metrics): UNKNOWN: No metric found (Are the filters properly set?)

[gust102]

Hi,

I have an issue with this command :

/usr/lib64/nagios/plugins/centreon_plugins.pl --plugin cloud::azure::management::monitor::plugin \
--custommode='api' \
--mode='get-metrics' \
--subscription=xxx \
--tenant=xxx \
--client-id=xxx \
--client-secret=xxx \
--resource=xxx \
--resource-group=xxx \
--resource-namespace=microsoft.insights/components \
--resource-type=  \
--metric=requests/failed \
--aggregation=Count \
--interval=PT30M \
--filter-dimension="request/resultCode sw '42'" \
--warning-metric=1 --critical-metric=5

When there are no hits, i get:
UNKNOWN: No metric found (Are the filters properly set?)

Can't find any option to get OK instead of UNKNOWN when the filter is empty.

Hello :)

Have you tried the following generic options (which might do what you want):

--change-short-output --change-long-output :

Modify the short/long output that is returned by the plugin.
Syntax: --change-short-output=pattern~replacement~modifier
Most commonly used modifiers are i (case insensitive) and g (replace all occurrences).
Example: adding --change-short-output='OK~Up~gi' will replace all occurrences of 'OK', 'ok', 'Ok' or 'oK' with 'Up'

or

--output-ignore-labe :

Remove the status label ("OK:", "WARNING:", "UNKNOWN:", CRITICAL:") from the
beginning of the output.
Example: 'OK: Ram Total:...' will become 'Ram Total:...'

Hello,

But that would only change the output text, and still the exit code will be 3 (UNKNOWN)?
What I am looking for is "as long as ResultCode not starts with 42, everything is OK (exit 0)"

Hello :)

Ok I need more context about your needs, but my first impression is that you may need an additional option to accept certain return codes. Can you provide us the plugin output with the option --debug set ? (you can anonymized part that need it)?

Hello :)

Sorry for waiting, there is a PR that could solve your problem. Would you be able to test it to see if it solves your problem? Here is the new option:

<--change-output-adv>
Replace short output and exit code based on a "if" condition using the following variables:
short_output, exit_code.
Variables must be written either %{variable} or %(variable).
Example: adding --change-output-adv='%(short_ouput) =~ /UNKNOWN: No daemon/,OK: No daemon,OK' will 
change the following specific UNKNOWN result to an OK result.

#5155

[gust102]

How do I use this PR?
Because, when I use this option in current installation I get error:
Unknown option: change-output-adv at /usr/lib64/nagios/plugins/centreon/plugins/alternative/Getopt.pm line 81.

[lucie-dubrunfaut]

Hello :)

It's normal not to be able to use the option in the current develop branch of centreon-plugins. You need to be familiar with git branches and their use to be able to use the PR as it is currently proposed. If this is not the case, the option should be available soon in the January 2025 release.

[gust102]

Ok, I have now tried with this pull request, by updating output.pm.
The parameter --change-output-adv is working, but I will still get exit code 3 (UNKNOWN).

I want exit code 0 (green).

[lucie-dubrunfaut]

Hello :)

OK, I understand, but it's more complicated because this mode is designed with the philosophy that ‘No metrics’ is not good news given that we're trying to recover metrics. So changing the return code from 3 (UNKNOWN) to 0 (OK) seems to require a change in approach to what the mode proposes to do. So it would be more of an enhancement request to incorporate the behaviour you want rather than an issue itself. Enhancement requests are processed in the TheWatch Ideas section for voting (which helps us prioritise them).

[omercier]

Hi @gust102,
Can you show us the argument you have tried with option --change-output-adv?

[omercier]

Hi @gust102,
Can you try again with the code available here #5379 ?

[lucie-dubrunfaut]

Hello :)

Released in January 2025
I close this issue because this option should meet your needs. If not feel free to re-open it. :)
