cc @beorn7 EDIT: Practices and Guide/Tutorial on how to enable them e2e from Go client, through Prometheus to querying

It would be epic to give guide on how to implement exemplars. I am working on TAG Observability Whitepaper https://docs.google.com/document/d/19am_KCYWU28ebLiIXv_P3ji96edxCTscVb4CzemXV5A/edit and just removed bit too detailed piece about exemplars I...

Proposal: Move to Thanos-community or Thanos orgs.

I feel having this controller is a must-have for any Thanos deployment with receives (it works only on k8s, something like that is needed for other systems). This means we...

0.9.0: Validation of Rule Failed

1

0.9.0 rule with `project_id=gmp-eval-central` selector fails to be applied: ``` Error from server (isolating rules failed: set isolation selector project_id="test_project" on up{cluster="gmp-test-recording-rules",project_id="gmp-eval-central"}: conflicting label matcher project_id="gmp-eval-central" found): error when creating...

(This relates to unreleased feature from https://github.com/GoogleCloudPlatform/prometheus-engine/pull/776 PR) When the secret is configured in e.g. PodMonitoring but not found by the Prometheus we get nice Target Page error:  Hopefully...

export: Add support for Info, Stateset and gaugehistogram, metrics (new OM metric types).

1

Prometheus supports [OM metric types](https://github.com/prometheus/prometheus/blob/1ea477f4bcd04c580e51711dca346a06421b311c/model/textparse/interface.go#L115) (passed in metadata) since [2018](https://github.com/prometheus/prometheus/commit/c271ef456a0b696a389f7e607472c8c3573eafd1). From a quick glance [export returns error when OM is used with new types](https://github.com/GoogleCloudPlatform/prometheus-engine/blob/main/pkg/export/series_cache.go#L462), which is emits [debug log message](https://github.com/GoogleCloudPlatform/prometheus-engine/blob/main/pkg/export/series_cache.go#L242)....

Currently all commands run things in docker container (including e2e and kind). This has benefit of ultimate hermetization (less "why it works on my machine, but not on CI" moments)....

During [secret mgtmt](https://github.com/GoogleCloudPlatform/prometheus-engine/pull/783) work we noticed opportunity of helping users with missing RBACs (that has to be manually added for now). ## AC * Users are hinted what RBACs are...

High cardinality of Prometheus metrics in self-scrape scenarios (only self-deploy).

1

The way we configure scrape jobs causes bit high cardinality of `net_conntrack_dialer_conn_failed_total`. It would be nice to work with the upstream to provide an option to disable it, or improve...
