beorn7	c13b1ecfe9	Make chunk iterators more DRY This finally extracts all the common code of the two chunk iterators into one. Any future chunk encodings with fast access by index can use the same iterator by simply providing an indexAccessor. Other future chunk encodings without fast index access (like Gorilla-style) can still implement the chunkIterator interface as usual.	9 years ago
beorn7	32f280a3cd	Slim down the chunkIterator interface For one, remove unneeded methods. Then, instead of using a channel for all values, use a bufio.Scanner-like interface. This removes the need for creating a goroutine and avoids the (unnecessary) locking performed by channel sending and receiving. This will make it much easier to write new chunk implementations (like Gorilla-style encoding).	9 years ago

beorn7	b6fdb355d7	Move dump-heads into its own tool	9 years ago
beorn7	f193f2b8ef	Add a command to promtool that dumps metadata of heads.db I needed this today for debugging. It can certainly be improved, but it's already quite helpful. I refactored the reading of heads.db files out of persistence, which is an improvement, too. I made minor changes to the cli package to allow outputting via the io.Writer interface.	9 years ago

beorn7	75a6b460ef	Give TestEvictAndLoadChunkDescs more time to actually evict Obviously, it's really bad to depend on timing here. The proper fix would be to have something like WaitForIndexing for other things to wait for, too. For now, let's see if the wait time increase fixes the issue.	9 years ago
beorn7	fc7de5374a	Quarantine series upon problem writing to the series file This fixes https://github.com/prometheus/prometheus/issues/1059 , but not in the obvious way (simply not updating the persist watermark, because that's actually not that simple - we don't really know what has gone wrong exactly). As any errors relevant here are most likely caused by severe and unrecoverable problems with the series file, Using the now quarantine feature is the right step. We don't really have to be worried about any inconsistent state of the series because it will be removed for good ASAP. Another plus is that we don't have to declare the whole storage dirty anymore.	9 years ago

Tobias Schmidt	d7889e61bb	Detect code style violations in deeply nested files So far the style check did not recognize issues in files in deeply nested directories, e.g. retrieval/discovery/kubernetes/discovery.go.	9 years ago

beorn7	0ea5801e47	Handle errors caused by data corruption more gracefully This requires all the panic calls upon unexpected data to be converted into errors returned. This pollute the function signatures quite lot. Well, this is Go... The ideas behind this are the following: - panic only if it's a programming error. Data corruptions happen, and they are not programming errors. - If we detect a data corruption, we "quarantine" the series, essentially removing it from the database and putting its data into a separate directory for forensics. - Failure during writing to a series file is not considered corruption automatically. It will call setDirty, though, so that a crashrecovery upon the next restart will commence and check for that. - Series quarantining and setDirty calls are logged and counted in metrics, but are hidden from the user of the interfaces in interface.go, whith the notable exception of Append(). The reasoning is that we treat corruption by removing the corrupted series, i.e. a query for it will return no results on its next call anyway, so return no results right now. In the case of Append(), we want to tell the user that no data has been appended, though. Minor side effects: - Now consistently using filepath.* instead of path.*. - Introduced structured logging where I touched it. This makes things less consistent, but a complete change to structured logging would be out of scope for this PR.	9 years ago

Fabian Reinartz	d89c254849	Make copying alerting state safer. This considers static labels in the equality of alerts to avoid falsely copying state from a different alert definition with the same name across reloads. To be safe, it also copies the state map rather than just its pointer so that remaining collisions disappear after one evaluation interval.	9 years ago

Fabian Reinartz	1ede7b9d72	Consolidate TargetStatus into Target. This commit simplifies the TargetHealth type and moves the target status into the target itself. This also removes a race where error and last scrape time could have been out of sync.	9 years ago
Fabian Reinartz	2060a0a15b	Turn target group members into plain lists. As the scrape pool deduplicates targets now, it is no longer necessary to store a hash map for members of each group.	9 years ago
Fabian Reinartz	0d7105abee	Remove scrape config from Target. This commit removes the scrapeConfig entirely from Target. All identity defining parameters are thus immutable now and the mutex can be removed.. Target identity is now correctly defined by the labels and the full URL. This in particular includes URL parameters that are not specified in the label set. Fingerprint is also removed from hash to remove an unnecessary tight coupling to the common/model package.	9 years ago
Fabian Reinartz	75681b691a	Extract HTTP client from Target. The HTTP client is the same across all targets with the same scrape configuration. Thus, this commit moves it into the scrape pool.	9 years ago

Fabian Reinartz	76a8c6160d	Deduplicate targets in scrape pool. With this commit the scrape pool deduplicates incoming targets before scraping them. This way multiple target providers can produce the same target but it will be scraped only once.	9 years ago
Fabian Reinartz	84f74b9a84	Apply new scrape config on reload. This commit updates a target set's scrape configuration on reload. This will cause all running scrape loops to be stopped and started again with new parameters.	9 years ago
