Fabian Reinartz	479891c9be	Rename RuleManager to Manager, remove interface. This commits renames the RuleManager to Manager as the package name is 'rules' now. The unused layer of abstraction of the RuleManager interface is removed.	10 years ago
Fabian Reinartz	3ca11bcaf5	Switch Prometheus to promql package. This commit removes all functionality from rules/ that is now handled in promql/. All parts of Prometheus are changed to use the promql/ package.	10 years ago
Fabian Reinartz	5015c2a0e8	Make target manager source based. This commit shifts responsibility for maintaining targets from providers and pools to the target manager. Target groups have a source name that identifies them for updates.	10 years ago
Tobias Schmidt	7d71d354fd	Remove special listing of config.file in usage The -config.file parameter isn't required or any more special than the other flags. In order to avoid confusion, this change removes the special mention again. Instead, the error message if a config file couldn't be loaded is changed to mention the flag name.	10 years ago
Tobias Schmidt	35a44509fb	Improve readability of usage text Separates flag and description by a newline to make it easier to read the flags with long descriptions.	10 years ago
Fabian Reinartz	c012ca6039	Make help output readable. This commit increases the usability by grouping flags based on their first dot-separated group. Long flag descriptions are broken into lines printed with indentation.	10 years ago

beorn7	11bd9ce1bd	Increase resilience of the storage against data corruption - step 3. Step 3: Remember the mtime of series files and make use of it to detect series files that are not the one the checkpoint thinks they are.	10 years ago
beorn7	e25cca823c	Increase resilience of the storage against data corruption - step 2. Step 2: Add a flag -storage.local.pedantic-checks to check every series file. Also, remove countPersistedHeadChunks channel, which is unused.	10 years ago
beorn7	da7c0461c6	Rename persist queue len/cap to num/max chunks to persist. Remove deprecated flag storage.incoming-samples-queue-capacity.	10 years ago
beorn7	be11cb2b07	Remove the sample ingestion channel. The one central sample ingestion channel has caused a variety of trouble. This commit removes it. Targets and rule evaluation call an Append method directly now. To incorporate multiple storage backends (like OpenTSDB), storage.Tee forks the Append into two different appenders. Note that the tsdb queue manager had its own queue anyway. It was a queue after a queue... Much queue, so overhead... Targets have their own little buffer (implemented as a channel) to avoid stalling during an http scrape. But a new scrape will only be started once the old one is fully ingested. The contraption of three pipelined ingesters was removed. A Target is an ingester itself now. Despite more logic in Target, things should be less confusing now. Also, remove lint and vet warnings in ast.go.	10 years ago
beorn7	0056eaeb4f	Redesign series maintenance and chunk persistence.	10 years ago
beorn7	5bea942d8e	Improve various things around chunk encoding. A number of mostly minor things: - Rename chunk type -> chunk encoding. - After all, do not carry around the chunk encoding to all parts of the system, but just have one place where the encoding for new chunks is set based on the flag. The new approach has caveats as well, but the polution of so many method signatures is worse. - Use the default chunk encoding for new chunks of existing series. (Previously, only new _series_ would get chunks with the default encoding.) - Use an enum for chunk encoding. (But keep the version number for the flag, for reasons discussed previously.) - Add encoding() to the chunk interface (so that a chunk knows its own encoding - no need to have that in a different top-level function). - Got rid of newFollowUpChunk (which would keep the existing encoding for all chunks of a time series). Now only use newChunk(), which will create a chunk encoding according to the flag. - Simplified transcodeAndAdd. - Reordered methods of deltaEncodedChunk and doubleDeltaEncoded chunk to match the order in the chunk interface. - Only transcode if the chunk is not yet half full. If more than half full, add a new chunk instead.	10 years ago
beorn7	66e768f05e	Improve docstring for chunk type flag.	10 years ago
beorn7	13fcf1ddbc	Implement double-delta encoded chunks.	10 years ago
beorn7	af91fb8e31	Improve persisting chunks to disk. This is done by bucketing chunks by fingerprint. If the persisting to disk falls behind, more and more chunks are in the queue. As soon as there are "double hits", we will now persist both chunks in one go, doubling the disk throughput (assuming it is limited by disk seeks). Should even more pile up so that we end wit "triple hits", we will persist those first, and so on. Even if we have millions of time series, this will still help, assuming not all of them are growing with the same speed. Series that get many samples and/or are not very compressable will accumulate chunks faster, and they will soon get double- or triple-writes. To improve the chance of double writes, -storage.local.persistence-queue-capacity could be set to a higher value. However, that will slow down shutdown a lot (as the queue has to be worked through). So we leave it to the user to set it to a really high value. A more fundamental solution would be to checkpoint not only head chunks, but also chunks still in the persist queue. That would be quite complicated for a rather limited use-case (running many time series with high ingestion rate on slow spinning disks).	10 years ago
beorn7	8a1c195b54	Move emptiness check to the receivers.	10 years ago
beorn7	11b3c2387c	Improvements after review. - Increase samplesQueueCapacity. - Improve docstring for the above. - Accept a short waiting period for the ingest channel to become ready. This should depend on the http timeout, but 100ms is probably good enough to cushion bursts bigger than samplesQueueCapacity, while it is unlikely that anybody ever will set an HTTP timeout similarly short.	10 years ago
beorn7	d2ab49c396	Make the persist queue length configurable. Also, set a much higher default value. Chunk persist requests can be quite spiky. If you collect a large number of time series that are very similar, they will tend to finish up a chunk at about the same time. There is no reason we need to back up scraping just because of that. The rationale of the new default value is "1/8 of the chunks in memory".	10 years ago
Bjoern Rabenstein	5859b74f1b	Clean up license issues. - Move CONTRIBUTORS.md to the more common AUTHORS. - Added the required NOTICE file. - Changed "Prometheus Team" to "The Prometheus Authors". - Reverted the erroneous changes to the Apache License.	10 years ago

Bjoern Rabenstein	904acd43da	Add crash recovery. Fix the behavior if preload for non-existent series is requested. Instead of returning an error (which triggers a panic further up), simply count those incidents. They can happen regularly, we just want to know if they happen too frequently because that would mean the indexing is behind or broken. Change-Id: I4b2d1b93c4146eeea897d188063cb9574a270f8b	10 years ago
Bjoern Rabenstein	f1de5b0c4e	Run checkpointing of in-memory metrics and head chunks periodically. Checkpointing interval is now a command line flag. Along the way, several things were refactored. - Restructure the way the storage is started and stopped.. - Number of series in checkpoint is now a uint64, not a varint. (Breaks old checkpoints, needs wipe!) - More consistent naming and order of methods. Change-Id: I883d9170c9a608ee716bb0ab3d0ded8ca03760d9	10 years ago
