Julius Volz	ba29d07901	Show loaded rules in Status dashboard.	12 years ago
Matt T. Proud	2c3df44af6	Ensure database access waits until it is started. ... This commit introduces a channel message to ensure serving state has been reached with the storage stack before anything attempts to use it.	12 years ago
Julius Volz	adb87816f4	Put RuleManager concurrency in hands of caller, fix races.	12 years ago
Matt T. Proud	0d2d6e9a27	Include uptime in the status console. ... In order to help corroborate whether a Prometheus instance has flapped until meta-monitoring is in-place, we ought to provide the instance's start time in the console to aid in diagnostics.	12 years ago
Matt T. Proud	b063338ae6	Expand the in-memory arena size. ... We need to exercise this code path sooner versus later. This will be a cheap way of doing so.	12 years ago
Bernerd Schaefer	63d9988b9c	Drop unused writeMemoryInterval	12 years ago
Matt T. Proud	b224251981	Simplify compaction and expose database sizes. ... This commit simplifies the way that compactions across a database's keyspace occur due to reading the LevelDB internals. Secondarily it introduces the database size estimation mechanisms. Include database health and help interfaces. Add database statistics; remove status goroutines. This commit kills the use of Go routines to expose status throughout the web components of Prometheus. It also dumps raw LevelDB status on a separate /databases endpoint.	12 years ago
juliusv	92ad65ff13	Merge pull request #232 from prometheus/optimize/granular-storage-locking ... Synchronous memory appends and more fine-grained storage locks.	12 years ago
Matt T. Proud	d538b0382f	Include long-tail data deletion mechanism. ... This commit introduces the long-tail deletion mechanism, which will automatically cull old sample values. It is an acceptable hold-over until we get a resampling pipeline implemented. Kill legacy OS X documentation, too.	12 years ago
Julius Volz	ce1ee444f1	Synchronous memory appends and more fine-grained storage locks. ... This does two things: 1) Make TieredStorage.AppendSamples() write directly to memory instead of buffering to a channel first. This is needed in cases where a rule might immediately need the data generated by a previous rule. 2) Replace the single storage mutex by two new ones: - memoryMutex - needs to be locked at any time that two concurrent goroutines could be accessing (via read or write) the TieredStorage memoryArena. - memoryDeleteMutex - used to prevent any deletion of samples from memoryArena as long as renderView is running and assembling data from it. The LevelDB disk storage does not need to be protected by a mutex when rendering a view since renderView works off a LevelDB snapshot. The rationale against adding memoryMutex directly to the memory storage: taking a mutex does come with a small inherent time cost, and taking it is only required in few places. In fact, no locking is required for the memory storage instance which is part of a view (and not the TieredStorage).	12 years ago
Matt Proud	7f0d816574	Schedule the background compactors to run. ... This commit introduces three background compactors, which compact sparse samples together. 1. Older than five minutes is grouped together into chunks of 50 every 30 minutes. 2. Older than 60 minutes is grouped together into chunks of 250 every 50 minutes. 3. Older than one day is grouped together into chunks of 5000 every 70 minutes.	12 years ago
Julius Volz	af7920126c	Fix build errors and add default build step to "make".	12 years ago
Julius Volz	56324d8ce2	Make AST query storage non-global.	12 years ago
Matt T. Proud	3b9b1c6ab4	Define dependencies for web. stack concretely. ... This commit destroys the use of AppState, which makes passing concrete state along to various serving components onerous.	12 years ago
Matt T. Proud	ce45787dbf	Storage interface to TieredStorage. ... This commit drops the Storage interface and just replaces it with a publicized TieredStorage type. Storage had been anticipated to be used as a wrapper for testability but just was not used due to practicality. Merely overengineered. My bad. Anyway, we will eventually instantiate the TieredStorage dependencies in main.go and pass them in for more intelligent lifecycle management. These changes will pave the way for managing the curators without Law of Demeter violations.	12 years ago

Julius Volz	368a792dd2	Adjust memory queue size after change to send arrays over channel.	12 years ago
juliusv	b02debd69c	Merge pull request #205 from prometheus/julius-channel-arrays ... Send sample arrays instead of single samples over channels.	12 years ago

Matt T. Proud	3362bf36e2	Include curator status in web heads-up-display.	12 years ago
Matt T. Proud	6fac20c8af	Harden the tests against OOMs. ... This commit employs explicit memory freeing for the in-memory storage arenas. Secondarily, we take advantage of smaller channel buffer sizes in the test.	12 years ago
Bernerd Schaefer	c152aa514f	Always print version information when starting up	12 years ago

Bernerd Schaefer	033533c4c5	Capture build information and print with -version	12 years ago
Matt T. Proud	d468271e2f	Fix append queue telemetry and parameterize sizes. ... The original append queue telemetry never worked, because it was updated only upon the exit of the select statement, which would usually liberate the queues of contents. This has been fixed to be reported arbitrarily. The queue sizes are now parameterizable via flags.	12 years ago

Matt T. Proud	13ae29b304	Initial in-memory arena implementation. ... It is unbounded, and nothing uses it except for a gating flag in main.	12 years ago

Matt T. Proud	f2ded515b7	Support versioned telemetry providers. ... client_golang was updated to support full label-oriented telemetry, which introduced interface incompatibilities with the previous version of Prometheus. To alleviate this, a general fetching and processing dispatching system has been created, which discriminates and processes according to the version of input.	12 years ago

Matt T. Proud	efe61c18fa	Refactor target scheduling to separate facility. ... ``Target`` will be refactored down the road to support various nuanced endpoint types. Thusly incorporating the scheduling behavior within it will be problematic. To that end, the scheduling behavior has been moved into a separate assistance type to improve conciseness and testability. ``make format`` was also run.	12 years ago
