Way to list defined Metrics & Graphs?

Is there a way to list all registered instances of Metric & Graph? Use case is that when developing a plugin, whatever its type, its useful to re-use existing metric & graph definitions as not having to reinvent the wheel. However, it seems pretty difficult to determine which actually exist, given that we aren’t used metric_info anymore.

I often find myself instantiating a Metric only to find errors about it having been defined already in ~site/var/log/apache/error.log

I’d be fine with any method, be it some kind of clever CLI tool usage or even a piece of code to insert somewhere that goes through the registered instances & prints them to some kind of log file. Ideally I’d like a method that not only goes through base CheckMK, but also through installed third-party packages.

Thanks.

PS: I’m aware of this list, but that one has a couple of drawbacks:

  • seems to be pre-2.3.0/2.4.0 era
  • only lists the metric names, not their definitions, which is kind of important for scaling (bits? bytes?) and type to get right (e.g. number of bytes vs. bytes per second…)

AFAIK there is no way to do this anymore :frowning: However I would also appreciate if this functionality could be added to the new plugins API.

For me this was also a severe problem when migrating plugins to the new API since we built a plugin that parses Prometheus metrics and tries to reuse existing metric definitions (especially render functions). Our current workaround is to implement the required definitions ourselves.

Yeah, same, thanks. And then look at the logs & delete those for which the aforementioned error about duplicate metrics occurs. Definitely not the best way to go about things.
