Julius Volz	7e85711df0	Beginnings of a tiered index implementation. This reintroduces a LevelDB-based metrics index. Change-Id: I4111540301c52255a07b2f570761707a32f72c05	10 years ago
Julius Volz	c582ae73c2	Implement topk() and bottomk() functions. To achieve O(log n * k) runtime, this uses a heap to track the current bottom-k or top-k elements while iterating over the full set of available elements. It would be possible to reuse more code between topk and bottomk, but I decided for some more duplication for the sake of clarity. This fixes https://github.com/prometheus/prometheus/issues/399 Change-Id: I7487ddaadbe7acb22ca2cf2283ba6e7915f2b336	10 years ago
Bjoern Rabenstein	ca6a4fccef	Weed out our homegrown test.Tester. The Go stdlib has testing.TB now, which fulfills the exact same purpose. Change-Id: I0db9c73400e208ca376b932a02b7e3402234b87c	11 years ago
Julius Volz	4df5c7ab18	Optimize label matcher memory and runtime behavior. This optimizes the runtime and memory allocation behavior for label matchers other than type "Equal". Instead of creating a new set for every union of fingerprints, this simply adds new fingerprints to the existing set to achieve the same effect. The current behavior made a production Prometheus unresponsive when running a NotEqual match against the "instance" label (a label with high value cardinality).

Julius Volz	c7c0b33d0b	Add regex-matching support for labels. There are four label-matching ops for selecting timeseries now: - Equal: = - NotEqual: != - RegexMatch: =~ - RegexNoMatch: !~ Instead of looking up labels by a simple clientmodel.LabelSet (basically an equals op for every key/value pair in the set), timeseries fingerprint selection is now done via a list of metric.LabelMatchers.

Conor Hennessy	9a48010cec	Add a check for metrics directory existence. Previously on startup the program would just quit without stating explicitly why. Change-Id: I833b85eb74d2dd27cdc3f0f2e65d7bb1c42caa39	11 years ago
Matt T. Proud	4a87c002e8	Update low-level i'faces to reflect wireformats. This commit fixes a critique of the old storage API design, whereby the input parameters were always as raw bytes and never Protocol Buffer messages that encapsulated the data, meaning every place a read or mutation was conducted needed to manually perform said translations on its own. This is taxing. Change-Id: I4786938d0d207cefb7782bd2bd96a517eead186f	11 years ago
Matt T. Proud	1e37b23a17	Extract LRUCache into generic cache type. Change-Id: I402da4de408a44457daeec7497d2393c5f65ab66	11 years ago
Julius Volz	3b970c5133	Add variable interpolation to notification messages. This includes required refactorings to enable replacing the http client (for testing) and moving the NotificationReq type definitions to the "notifications" package, so that this package doesn't need to depend on "rules" anymore and that it can instead use a representation of the required data which only includes the necessary fields.	11 years ago
Julius Volz	35ee2cd3cb	Add alertmanager notification support to Prometheus. Alert definitions now also have mandatory SUMMARY and DESCRIPTION fields that get sent along a firing alert to the alert manager.	11 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
Bernerd Schaefer	b886a14cfc	Remove race conditions from UncertaintyGroup	12 years ago
Matt T. Proud	561974308d	Add curation remark table and refactor error mgmt. The curator requires the existence of a curator remark table, which stores the progress for a given curation policy. The tests for the curator create an ad hoc table, but core Prometheus presently lacks said table, which this commit adds. Secondarily, the error handling for the LevelDB lifecycle functions in the metric persistence have been wrapped into an UncertaintyGroup, which mirrors some of the functions of sync.WaitGroup but adds error capturing capability to the mix.	12 years ago
Julius Volz	6cb3c51d24	Add sort() and sort_desc() expression language functions.	12 years ago
Matt T. Proud	6dcaa28806	Include LevelDB fixture generators for curator. This will help reduce common boilerplate for our test process with respect to LevelDB-related things.	12 years ago
Matt T. Proud	b86b0ea41a	Create temporary directory handler.	12 years ago
Matt T. Proud	8358e5ee44	Update embedding script to support BSD find. Mac OS X (shudder) needs to have a slightly modified find execution pattern.	12 years ago
Johannes 'fish' Ziemke	1f80b17cb7	Remove temporary debugging.	12 years ago
Johannes 'fish' Ziemke	a985a723a1	Remove echo -e because it's not available on Travis. Instead, files.go gets piped through gofmt.	12 years ago
Johannes 'fish' Ziemke	aed8270a97	Enable debugging (set -x) on embed-static.sh.	12 years ago
Johannes 'fish' Ziemke	2434bac219	Detect mime type on runtime instead of hardcoding.	12 years ago
Johannes 'fish' Ziemke	59f8ba9121	Replace popd/pushd because travis' /bin/sh doesn't support it.	12 years ago
Johannes 'fish' Ziemke	fc16580b4c	Ship assets in compiled binary. - utility/embed-static.sh, get called in Makefile to create go map from files - web/blob/blob.go implements http Handle for serving the files from the map - web/status.go uses blog.GetFile() to get the template file The assets are gzipped and decompressed on demand.	12 years ago
Julius Volz	a908e397bc	Integrate cleanups for comments in PR70.	12 years ago
Julius Volz	c3d31febd6	Move durationToString to common place and cleanup error handling.	12 years ago
Julius Volz	d67e4b9131	Address outstanding comments from PR/47 and other cleanups.	12 years ago
Matt T. Proud	4cd153555e	Swap ``time.Now`` with testable ``Time.Now``.	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	3ac5d48b1a	Impl' storage i'faces and fix non-idiomatic warts. This change includes implementation of most major storage layer features, albeit some imperfect. It also includes nascent telemetry bindings, too.	12 years ago
