beorn7	c0879d64cf	promql: Separate `Point` into `FPoint` and `HPoint` In other words: Instead of having a “polymorphous” `Point` that can either contain a float value or a histogram value, use an `FPoint` for floats and an `HPoint` for histograms. This seemingly small change has a _lot_ of repercussions throughout the codebase. The idea here is to avoid the increase in size of `Point` arrays that happened after native histograms had been added. The higher-level data structures (`Sample`, `Series`, etc.) are still “polymorphous”. The same idea could be applied to them, but at each step the trade-offs needed to be evaluated. The idea with this change is to do the minimum necessary to get back to pre-histogram performance for functions that do not touch histograms. Here are comparisons for the `changes` function. The test data doesn't include histograms yet. Ideally, there would be no change in the benchmark result at all. First runtime v2.39 compared to directly prior to this commit: ``` name old time/op new time/op delta RangeQuery/expr=changes(a_one[1d]),steps=1-16 391µs ± 2% 542µs ± 1% +38.58% (p=0.000 n=9+8) RangeQuery/expr=changes(a_one[1d]),steps=10-16 452µs ± 2% 617µs ± 2% +36.48% (p=0.000 n=10+10) RangeQuery/expr=changes(a_one[1d]),steps=100-16 1.12ms ± 1% 1.36ms ± 2% +21.58% (p=0.000 n=8+10) RangeQuery/expr=changes(a_one[1d]),steps=1000-16 7.83ms ± 1% 8.94ms ± 1% +14.21% (p=0.000 n=10+10) RangeQuery/expr=changes(a_ten[1d]),steps=1-16 2.98ms ± 0% 3.30ms ± 1% +10.67% (p=0.000 n=9+10) RangeQuery/expr=changes(a_ten[1d]),steps=10-16 3.66ms ± 1% 4.10ms ± 1% +11.82% (p=0.000 n=10+10) RangeQuery/expr=changes(a_ten[1d]),steps=100-16 10.5ms ± 0% 11.8ms ± 1% +12.50% (p=0.000 n=8+10) RangeQuery/expr=changes(a_ten[1d]),steps=1000-16 77.6ms ± 1% 87.4ms ± 1% +12.63% (p=0.000 n=9+9) RangeQuery/expr=changes(a_hundred[1d]),steps=1-16 30.4ms ± 2% 32.8ms ± 1% +8.01% (p=0.000 n=10+10) RangeQuery/expr=changes(a_hundred[1d]),steps=10-16 37.1ms ± 2% 40.6ms ± 2% +9.64% (p=0.000 n=10+10) RangeQuery/expr=changes(a_hundred[1d]),steps=100-16 105ms ± 1% 117ms ± 1% +11.69% (p=0.000 n=10+10) RangeQuery/expr=changes(a_hundred[1d]),steps=1000-16 783ms ± 3% 876ms ± 1% +11.83% (p=0.000 n=9+10) ``` And then runtime v2.39 compared to after this commit: ``` name old time/op new time/op delta RangeQuery/expr=changes(a_one[1d]),steps=1-16 391µs ± 2% 547µs ± 1% +39.84% (p=0.000 n=9+8) RangeQuery/expr=changes(a_one[1d]),steps=10-16 452µs ± 2% 616µs ± 2% +36.15% (p=0.000 n=10+10) RangeQuery/expr=changes(a_one[1d]),steps=100-16 1.12ms ± 1% 1.26ms ± 1% +12.20% (p=0.000 n=8+10) RangeQuery/expr=changes(a_one[1d]),steps=1000-16 7.83ms ± 1% 7.95ms ± 1% +1.59% (p=0.000 n=10+8) RangeQuery/expr=changes(a_ten[1d]),steps=1-16 2.98ms ± 0% 3.38ms ± 2% +13.49% (p=0.000 n=9+10) RangeQuery/expr=changes(a_ten[1d]),steps=10-16 3.66ms ± 1% 4.02ms ± 1% +9.80% (p=0.000 n=10+9) RangeQuery/expr=changes(a_ten[1d]),steps=100-16 10.5ms ± 0% 10.8ms ± 1% +3.08% (p=0.000 n=8+10) RangeQuery/expr=changes(a_ten[1d]),steps=1000-16 77.6ms ± 1% 78.1ms ± 1% +0.58% (p=0.035 n=9+10) RangeQuery/expr=changes(a_hundred[1d]),steps=1-16 30.4ms ± 2% 33.5ms ± 4% +10.18% (p=0.000 n=10+10) RangeQuery/expr=changes(a_hundred[1d]),steps=10-16 37.1ms ± 2% 40.0ms ± 1% +7.98% (p=0.000 n=10+10) RangeQuery/expr=changes(a_hundred[1d]),steps=100-16 105ms ± 1% 107ms ± 1% +1.92% (p=0.000 n=10+10) RangeQuery/expr=changes(a_hundred[1d]),steps=1000-16 783ms ± 3% 775ms ± 1% -1.02% (p=0.019 n=9+9) ``` In summary, the runtime doesn't really improve with this change for queries with just a few steps. For queries with many steps, this commit essentially reinstates the old performance. This is good because the many-step queries are the one that matter most (longest absolute runtime). In terms of allocations, though, this commit doesn't make a dent at all (numbers not shown). The reason is that most of the allocations happen in the sampleRingIterator (in the storage package), which has to be addressed in a separate commit.

Julien Pivotto	391473141d	Check health & ready: move to flags (#12223 ) This makes it more consistent with other command like import rules. We don't have stricts rules and uniformity accross promtool unfortunately, but I think it's better to only have the http config on relevant check commands to avoid thinking Prometheus can e.g. check the config over the wire.

Julien Pivotto	ce55e5074d	Add 'keep_firing_for' field to alerting rules This commit adds a new 'keep_firing_for' field to Prometheus alerting rules. The 'resolve_delay' field specifies the minimum amount of time that an alert should remain firing, even if the expression does not return any results. This feature was discussed at a previous dev summit, and it was determined that a feature like this would be useful in order to allow the expression time to stabilize and prevent confusing resolved messages from being propagated through Alertmanager. This approach is simpler than having two PromQL queries, as was sometimes discussed, and it should be easy to implement. This commit does not include tests for the 'resolve_delay' field. This is intentional, as the purpose of this commit is to gather comments on the proposed design of the 'resolve_delay' field before implementing tests. Once the design of the 'resolve_delay' field has been finalized, a follow-up commit will be submitted with tests."

Sam Jewell	f88a0a7d83	Update example rules file to be valid with the default scrape config (#11692 ) * Update docs example rules for default config The prometheus download includes a default config to scrape itself. This self-scraping prometheus doesn't include any metric named as `http_inprogress_requests`, but does include one named `prometheus_http_requests_total`. Updating this example rule in the docs to one which can be used out-of-the-box with the default download would be a nice improvement.

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.
