Graphite and icingaweb2: do not show certain graphs

Icinga Web Modules Visualization, Metrics & Reporting
1

Hi.

I have been using icingaweb2 with graphite for more than 2 years, which works very well.
Also the adjustments with templates (/etc/icingaweb/modules/graphite/) work as desired.

But there is one question:
Is it possible not to display certain graphs in icingaweb2?
(Not every graph is necessary)

Thanks in advance.

Greetings

If you don’t need the metrics, set the enable_perfdata attribute to false in your host/service objects. This disables collecting the metrics in Icinga itself.

https://icinga.com/docs/icinga2/latest/doc/09-object-types/#service

Existing wsp files need to be purged manually from whisper.

Cheers,
Michael

That’s very helpful.
Thank you very much.

To become even more precise:
A check like cluster-zone returns several performance data,
among others:
last_messages_sent
and
last_messages_received.

For these two timestamps a graph doesn’t seem to make much sense to me.

Is there also a way not to display these graphs?

Thanks in advance.

One thing comes to mind - configure the carbon cache receiver in a way that it drops metrics by these patterns. In terms of the Icinga built-in checks there’s no support for filtering metrics away, either all or nothing.

That matches perfectly.

Thank you very much.

If anybody else is interested in this,
here is an example of how to manage this.

The blacklist.conf (e.g. /etc/carbon/blacklist.conf) for the
above mentioned cluster-zone check may look like this

^.+\.cluster-zone\..+last_messages_sent.+$
^.+\.cluster-zone\..+last_messages_received.+$

The matching metrics will be dropped by carbon-cache.
Old metrics will still be available and have to be delete manually.

Please note, that
USE_WHITELIST = True
has to be set in the carbon.conf (this enables whitelisting and blacklisting)
