Matthieu MOREL	bae9a21200	Merge branch 'main' into linter/nilerr Signed-off-by: Matthieu MOREL <matthieu.morel35@gmail.com>	2 years ago
beorn7	5b53aa1108	style: Replace `else if` cascades with `switch` Wiser coders than myself have come to the conclusion that a `switch` statement is almost always superior to a statement that includes any `else if`. The exceptions that I have found in our codebase are just these two: * The `if else` is followed by an additional statement before the next condition (separated by a `;`). * The whole thing is within a `for` loop and `break` statements are used. In this case, using `switch` would require tagging the `for` loop, which probably tips the balance. Why are `switch` statements more readable? For one, fewer curly braces. But more importantly, the conditions all have the same alignment, so the whole thing follows the natural flow of going down a list of conditions. With `else if`, in contrast, all conditions but the first are "hidden" behind `} else if `, harder to spot and (for no good reason) presented differently from the first condition. I'm sure the aforemention wise coders can list even more reasons. In any case, I like it so much that I have found myself recommending it in code reviews. I would like to make it a habit in our code base, without making it a hard requirement that we would test on the CI. But for that, there has to be a role model, so this commit eliminates all `if else` occurrences, unless it is autogenerated code or fits one of the exceptions above.

beorn7	c3c7d44d84	lint: Adjust to the lint warnings raised by current versions of golint-ci We haven't updated golint-ci in our CI yet, but this commit prepares for that. There are a lot of new warnings, and it is mostly because the "revive" linter got updated. I agree with most of the new warnings, mostly around not naming unused function parameters (although it is justified in some cases for documentation purposes – while things like mocks are a good example where not naming the parameter is clearer). I'm pretty upset about the "empty block" warning to include `for` loops. It's such a common pattern to do something in the head of the `for` loop and then have an empty block. There is still an open issue about this: https://github.com/mgechev/revive/issues/810 I have disabled "revive" altogether in files where empty blocks are used excessively, and I have made the effort to add individual `// nolint:revive` where empty blocks are used just once or twice. It's borderline noisy, though, but let's go with it for now. I should mention that none of the "empty block" warnings for `for` loop bodies were legitimate.

Bryan Boreham	b987afa7ef	labels: simplify call to get Labels from Builder It took a `Labels` where the memory could be re-used, but in practice this hardly ever benefitted. Especially after converting `relabel.Process` to `relabel.ProcessBuilder`. Comparing the parameter to `nil` was a bug; `EmptyLabels` is not `nil` so the slice was reallocated multiple times by `append`. Lastly `Builder.Labels()` now estimates that the final size will depend on labels added and deleted. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	0c09c3feb0	scrape sync: avoid copy of labels for dropped targets Since the Target object was just created in this function, nobody else has a reference to it and there are no concerns about it being modified concurrently so we don't need to copy the value.

Bryan Boreham	b96b89ef8b	Merge pull request #12048 from bboreham/faster-targets Scraping targets are synced by creating the full set, then adding/removing any which have changed. This PR speeds up the process of creating the full set. I added a benchmark for `TargetsFromGroup`; it uses configuration from a typical Kubernetes SD. The crux of the change is to do relabeling inside labels.Builder instead of converting to labels.Labels and back again for every rule. The change is broken into several commits for easier review. This is a breaking change to `scrape.PopulateLabels()`, but `relabel.Process` is left as-is, with a new `relabel.ProcessBuilder` option.	2 years ago

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.

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

Björn Rabenstein	a61c4b266a	scrape: Fix accept header, now for real (#11552 ) This reinstates the behavior of v2.39. The header got messed up in the sparsehistogram when the change of the version in main was merged into it (and the merge conflict had to be resolved). I don't think the current state will actually break anyone, although it is technically possible. I propose to merge this into the bugfix branch in any case, but I think we can wait for other bugfixes before cutting a v2.40.1. (Unless, of course, somebody reports an actual breakage because of the header.) Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
Björn Rabenstein	54ce07e9a0	scrape: Fix accept header (#11542 ) First of all, there was a typo: `encoding=delimited` was a left-over in the `scrapeAcceptHeader`. Second, the recently updated `version=1.0.0` prevents current versions of client_golang to negotiate OpenMetrics, as they expect `version=0.0.1` or no version at all.

I've experimented a bunch in #10627 to figure out that this approach doesn't cause memory increase. Beyond that, just using this info in _any_ other context is causing a memory increase. The change fixed a bunch of long-standing in the OTel Collector that the community was waiting on and release is blocked on a few downstream distrubutions of OTel Collector waiting on a fix. I propose to merge this change in while I investigate what is happening.
