Charles Korn	e023d896f2	Correct statement in docs about query results returning either floats or histograms but not both. (#11880 ) * Correct statement in docs about query results returning either floats or histograms but not both. * Move documentation for range and instant vectors under their corresponding headings.

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.

Julius Volz	b57deb6eb0	Add /api/v1/format_query API endpoint for formatting queries (#11036 ) * Add /api/v1/format_query API endpoint for formatting queries This uses the formatting functionality introduced in https://github.com/prometheus/prometheus/pull/10544. I've chosen "query" instead of "expr" in both the endpoint and parameter names to stay consistent with the existing API endpoints. Otherwise, I would have preferred to use the term "expr".

beorn7	9eafed0f79	promql: Add `histogram_count` and `histogram_sum` This follow a simple function-based approach to access the count and sum fields of a native Histogram. It might be more elegant to implement “accessors” via the dot operator, as considered in the brainstorming doc [1]. However, that would require the introduction of a whole new concept in PromQL. For the PoC, we should be fine with the function-based approch. Even the obvious inefficiencies (rate'ing a whole histogram twice when we only want to rate each the count and the sum once) could be optimized behind the scenes. Note that the function-based approach elegantly solves the problem of detecting counter resets in the sum of observations in the case of negative observations. (Since the whole native Histogram is rate'd, the counter reset is detected for the Histogram as a whole.) We will decide later if an “accessor” approach is really needed. It would change the example expression for average duration in functions.md from histogram_sum(rate(http_request_duration_seconds[10m])) / histogram_count(rate(http_request_duration_seconds[10m])) to rate(http_request_duration_seconds.sum[10m]) / rate(http_request_duration_seconds.count[10m]) [1]: https://docs.google.com/document/d/1ch6ru8GKg03N02jRjYriurt-CZqUVY09evPg6yKTA1s/edit Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

beorn7	b39f2739e5	PromQL: Always enable negative offset and @ modifier This follows the line of argument that the invariant of not looking ahead of the query time was merely emerging behavior and not a documented stable feature. Any query that looks ahead of the query time was simply invalid before the introduction of the negative offset and the @ modifier. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
beorn7	8fdfa52976	API: Promote remote-write-receiver to stable Since `/api/v1/write` is a mutating endpoint, we should still activate the remote-write-receiver explicitly. But we should do it in the same way as the other mutating endpoints, i.e. via a flag `--web.enable-remote-write-receiver`. This commit marks the feature flag as deprecated, i.e. it still works but logs a warning on startup. This enables users to seamlessly migrate. With the next minor release, we can start ignoring the feature flag (but still warn a user that is trying to use it). Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
