I pushed some commits with small fixes. I will squash the commits after the review, just didn't want to force push now. |

There was a problem hiding this comment.
Is it the case then that granular metrics are metrics with the above properties?

Sure, I think I'll squash all commits following "Extend metrics library" into it. I separated some code reshuffling into the first commit, so that it's clearer what code is new and what is just moved. |

This commit is a preparation for the further extension of pkg/metrics. There are no functional changes, only moving code around: - moved helpers for creating metrics from metricwithpod.go and granularmetric.go to per-type files: counter.go, gauge.go and histogram.go - renamed labels.go to filteredlabels.go Signed-off-by: Anna Kapuscinska <anna@isovalent.com>
This is a general rewrite of pkg/metrics library, but it a fully backwards compatible way. Goals and key components are described in doc.go. Fixes: #2376 Signed-off-by: Anna Kapuscinska <anna@isovalent.com>

This is a general rewrite of
pkg/metricslibrary, but it a fully backwardscompatible way. Goals and key components are described in
doc.go, so I wouldsuggest starting the review there :)
Here is the Tetragon metrics framework proposal, covering the bigger picture including future plans. The "Goals" and "Proposal/Library" sections are copied into
doc.go.For usage examples see #2604 (defining health metrics group, migrating some custom metrics & collectors to the new interface).
Fixes: #2376
