Required for all PRs:

  • Signed CLA.
  • Associated README.md updated.
  • Has appropriate unit tests.

This PR adds the ability to query Consul Catalog for published prometheus metric endpoints.

Tests are not my strong suit, I will add them if this PR makes sense and there are no other issues with it.

Thanks the PR, this looks very interesting and useful. I'm really busy finalizing 1.10 up now so I'll have to take a closer look in a few weeks.

The code looks quite good already. I have some comments in the code, especially about using or rather not using log. Please also rebase the code to the current master!

Almost perfect. :-) Thanks @mmolnar for keep this going! I added a comment regarding the potential "log-spam" issue and additionally found that currently refreshConsulServices() always returns nil as error. Can you please take a look there if we can come up with a refined "success" definition (see my comment in the code)?

Wow that was quick!
One cosmetic thing: can you please move the reset of lastQueryFailed out of the if clause. I'm always getting nervous when dealing with states, so it's better to involve the least number of branches possible... :-)

Oh and please check the linter-issues as we are trying hard to squash them all.

This leaves the linter issues (see https://github.com/influxdata/telegraf/pull/5464/checks?check_run_id=2820187786)
You can check your branch locally running make lint-branch...

The code looks good to me. However, could you add the example config and some documentation to the README?

I must have messed something up while rebasing and pushing the requested changes to my fork...
It was not my intention to close this PR.

The changes are still available in the master branch of my fork.
