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.

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.

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

Robert Fratto	bc72a718c4	Initial draft of prometheus-agent (#8785 ) * Initial draft of prometheus-agent This commit introduces a new binary, prometheus-agent, based on the Grafana Agent code. It runs a WAL-only version of prometheus without the TSDB, alerting, or rule evaluations. It is intended to be used to remote_write to Prometheus or another remote_write receiver. By default, prometheus-agent will listen on port 9095 to not collide with the prometheus default of 9090. Truncation of the WAL cooperates on a best-effort case with Remote Write. Every time the WAL is truncated, the minimum timestamp of data to truncate is determined by the lowest sent timestamp of all samples across all remote_write endpoints. This gives loose guarantees that data from the WAL will not try to be removed until the maximum sample lifetime passes or remote_write starts functionining.

Tom Wilkie	d479151f1f	Various enhancements and refactorings for remote write receiver: - Remove unrelated changes - Refactor code out of the API module - that is already getting pretty crowded. - Don't track reference for AddFast in remote write.

For now, its easier and safer to always use the 'slow' path. - Return 400 on out of order samples. - Use remote.DecodeWriteRequest in the remote write adapters. - Put this behing the 'remote-write-server' feature flag - Add some (very) basic docs. - Used named return & add test for commit error propagation Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>	4 years ago

Julius Volz	3470ee1fbf	Make React UI the default, keep old UI under /classic (#8142 ) The React app's assets are now served under /assets, while all old custom web assets (including the ones for console templates) are now served from /classic/static. I tested different combinations of --web.external-url and --web.route-prefix with proxies in front, and I couldn't find a problem yet with the routing. Console templates also still work. While migrating old endpoints to /classic, I noticed that /version was being treated like a lot of the old UI pages, with readiness check handler in front of it, etc. I kept it in /version and removed that readiness wrapper, since it doesn't seem to be needed for that endpoint.

Julien Pivotto	e96d786fb8	Stop CMUX and GRPC servers even with stale connections (#7810 ) I have received a recent report for a user which confirms that sometime the GRPC server does not stop propery. It appears that there are 2 issues: 1. The cmux server can refuse to stop if there are stale connections. For that we set the ReadTimeout. 2. The GRPC server graceful stop can never finish. What this PR avoids is: ``` goroutine 227 [semacquire, 2 minutes]: sync.runtime_Semacquire(0xc00059a75c) /usr/local/go/src/runtime/sema.go:56 +0x42 sync.(WaitGroup).Wait(0xc00059a75c) /usr/local/go/src/sync/waitgroup.go:130 +0x64 google.golang.org/grpc.(Server).GracefulStop(0xc00059a600) ``` This PR stops the GRPC server after 15s.
