Łukasz Mierzwa	e1b7082008	Show individual scrape pools on /targets page (#11142 ) * Add API endpoints for getting scrape pool names This adds api/v1/scrape_pools endpoint that returns the list of names of all the scrape pools configured. Having it allows to find out what scrape pools are defined without having to list and parse all targets. The second change is adding scrapePool query parameter support in api/v1/targets endpoint, that allows to filter returned targets by only finding ones for passed scrape pool name. Both changes allow to query for a specific scrape pool data, rather than getting all the targets for all possible scrape pools. The problem with api/v1/targets endpoint is that it returns huge amount of data if you configure a lot of scrape pools. Signed-off-by: Łukasz Mierzwa <l.mierzwa@gmail.com> * Add a scrape pool selector on /targets page Current targets page lists all possible targets. This works great if you only have a few scrape pools configured, but for systems with a lot of scrape pools and targets this slow things down a lot. Not only does the /targets page load very slowly in such case (waiting for huge API response) but it also take a long time to render, due to huge number of elements. This change adds a dropdown selector so it's possible to select only intersting scrape pool to view. There's also scrapePool query param that will open selected pool automatically.

Jens Erat	728fdc959e	Kubernetes SD: disable resync timer While originally the resync period also forced refreshing from Kubernetes API server, this has been removed for some years now because watching the API server got more stable [1]. Today, this just results in all entities being sent to the service discovery again, which is valid from a general Prometheus perspective, but results in unnecessary CPU load and also breaks service discovery metrics. In especially, this makes monitoring "do we actually observe changes from Kubernetes API server" impossible (receiving constant updates from Kubernetes service discovery is a pretty valid assumption, for example nodes get frequent status updates, ...).

Bryan Boreham	bec5abc4dc	scrape: remove unsafe code The `yolostring` routine was intended to avoid an allocation when converting from a `[]byte` to a `string` for map lookup. However, since 2014 Go has recognized this pattern and does not make a copy of the data when looking up a map. So the unsafe code is not necessary. In line with this, constants like `scrapeHealthMetricName` also become `[]byte`. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Bryan Boreham	dbd7021cc2	promql: add test for race conditions in query engine (#11743 ) * promql: refactor BenchmarkRangeQuery so we can re-use test cases Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * promql: add test for race conditions in query engine Note we skip large count_values queries - `count_values` allocates a slice per unique value in the output, and this test has unique values on every step of every series so it adds up to a lot of slices. Add Go runtime overhead for checking `-race`, and it chews up many gigabytes. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * TestConcurrentRangeQueries: wait before starting goroutine Instead of starting 100 goroutines which just wait for the semaphore.

Bryan Boreham	10b27dfb84	Simplify IndexReader.Series interface Instead of passing in a `ScratchBuilder` and `Labels`, just pass the builder and the caller can extract labels from it. In many cases the caller didn't use the Labels value anyway. Now in `Labels.ScratchBuilder` we need a slightly different API: one to assign what will be the result, instead of overwriting some other `Labels`. This is safer and easier to reason about.

Bryan Boreham	abd9909595	Update package storage/remote for new labels.Labels type `QueueManager.externalLabels` becomes a slice rather than a `Labels` so we can index into it when doing the merge operation. Note we avoid calling `Labels.Len()` in `labelProtosToLabels()`. It isn't necessary - `append()` will enlarge the buffer and we're expecting to re-use it many times. Also, we now validate protobuf input before converting to Labels. This way we can detect errors first, and we don't place unnecessary requirements on the Labels structure. Re-do seriesFilter using labels.Builder (albeit N^2). Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Bryan Boreham	56fefcd812	Update package promql for new labels.Labels type We use `labels.Builder` to parse metrics, to avoid depending on the internal implementation. This is not efficient, but the feature is only used in tests. It wasn't efficient previously either - calling `Sort()` after adding each label. `createLabelsForAbsentFunction` also uses a Builder now, and gets an extra `map` to replace the previous `Has()` usage.
