Feature idea summary

Cgroups plugin supports only proportional and max Block IO policies. We should support BFQ scheduler as well. Disk stats for the scheduler are in blkio.bfq.io_service_bytes and blkio.bfq.io_serviced files.

according to apache/skywalking#6686 (comment) , we can adopt the agent image for conveniency in the agent JDK version E2E tests

This will give us metric on healtcheck and more granularity on checks we want to have.

This is a reminder for me or a task if anyone wants :P

Basically, The last two questions aren't really regex's questions.

To do:

• Move said questions to correct place.
• Add new regex questions (Python related!)?
• Maybe add a new ## Regex section, as it is a valuable skill

Prometheus v2.26.0 has the flag --enable-feature=promql-negative-offset to enable negative offset.
It works fine.

But I can't enable it with Thanos 0.19.0.
It looks like the flag is not available for Thanos Query.
So the next query my_metric_status offset -24h fails with the error 1:31: parse error: unexpected <op:-> in offset, expected duration

Is this feature implemented?

What happened?

After being fine for a couple days, Prometheus mysteriously started crashing with this error:

level=error ts=2020-09-02T15:16:55.096Z caller=query_logger.go:87 component=activeQueryTracker msg="Error opening query log file" file=/prometheus/queries.active err="open /prometheus/queries.active: permission denied"
panic: Unable to create mmap-ed active query log

Is your feature request related to a problem? Please describe.
It's very easy to see ingester and ha ring status, but distributor ring status is only sort of viewable via Consul

Describe the solution you'd like
A status page that shows the distributor ring status similar to how we can currently view ingester ring status.

Describe alternatives you've considered
Currently I ta

I recently(ish) bumped client-go and other deps in the release-2.0 branch but did not have a chance to port these changes to master as well. I believe this is a good first issue for new contributors.

This is the original PR that needs to be ported to master branch. kubernetes/kube-state-metrics#1328 Note master branch does not have the vendor directory anymore.

What is missing?
kube-prometheus ships by default grafana, but there are no alerts around it. Since upstream project has a monitoring mixin we may as well use it.

Why do we need it?
To provide alerts/dashboards for grafana OOTB.

What did you expect to see?

I'm expecting to be able to filter out the requests from blackbox exporter in my access logs.
So, please, add a user agent header that container the "blackbox exporter" string somewhere.

What did you see instead?

I see User-Agent: Go-http-client/1.1
Not easy to filter in the access logs...

It would be awesome if the metrics could include the node's topology.kubernetes.io/region & topology.kubernetes.io/zone (not sure what the non-AWS fields are called). That would help quickly identify patterns in the results. e.g., zone "a" is slower than zone "b" or that cross-zone traffic is what's causing a large spike in response times. Not sure if this is possible within the framework of this
