Matt T. Proud	6b2be5024e	Merge pull request #279 from prometheus/refactor/storage-semaphore Cleanups in tiered storage and apply semaphores.	12 years ago
Matt T. Proud	ef1d5fd8a2	Introduce semaphores for tiered storage. This commit wraps the tiered storage access componnets in semaphores, since we can handle several concurrent memory reads.	12 years ago
Matt T. Proud	0d46f6b42a	Merge pull request #285 from prometheus/fix/storage/states Add storage state guards and transition callbacks.	12 years ago
Matt T. Proud	819045541e	Code Review: Make double-drain a panic.	12 years ago

Matt T. Proud	beaaf386e7	Add storage state guards and transition callbacks. To ensure that we access tiered storage in the proper way, we have guards now.	12 years ago
Matt T. Proud	abb5353ade	Merge pull request #283 from prometheus/feature/storage/consult-watermark Include LRU cache for fingerprint watermarks.	12 years ago
Matt T. Proud	52a1e50dda	Merge pull request #284 from prometheus/refactor/storage/notify-when-available Ensure database access waits until it is started.	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
Matt T. Proud	cbe2f3a7b1	Include LRU cache for fingerprint watermarks.	12 years ago
juliusv	115437ad1f	Merge pull request #278 from prometheus/debug/query-timings Add debug timers to instant and range queries.	12 years ago
Julius Volz	51689d965d	Add debug timers to instant and range queries. This adds timers around several query-relevant code blocks. For now, the query timer stats are only logged for queries initiated through the UI. In other cases (rule evaluations), the stats are simply thrown away. My hope is that this helps us understand where queries spend time, especially in cases where they sometimes hang for unusual amounts of time.	12 years ago
Matt T. Proud	c594d18f54	Merge pull request #282 from prometheus/fix/race/targetpool Fix race conditions in TargetPool.	12 years ago
Matt T. Proud	d4db3cf00b	Code Review: Last replacement wins.	12 years ago
Matt T. Proud	9cde48754b	Fix race conditions in TargetPool. The race condition detector found a few anomalies whereby a TargetPool could be read during a mutation. This has been fixed.	12 years ago
Matt T. Proud	d169e1d282	Merge pull request #281 from prometheus/feature/build/race-condition-binary Include race condition runner.	12 years ago
Matt T. Proud	2ee6e32847	Include race condition runner.	12 years ago
juliusv	95adf1958b	Merge pull request #280 from prometheus/cleanup/rules-concurrency Put RuleManager concurrency in hands of caller, fix races.	12 years ago
Julius Volz	adb87816f4	Put RuleManager concurrency in hands of caller, fix races.	12 years ago
Matt T. Proud	9215580488	Include race condition binary target. The race condition binary target is special in that it needs to explicitly link against the dependent libraries and recompile the CGO bindings. Because of this, we have a new build target that produces these binaries.	12 years ago
juliusv	6c36beb764	Merge pull request #269 from prometheus/feature/view-tracing Conditionalize disk initializations.	12 years ago
Matt T. Proud	8339a189cb	Code Review: Fix seriesPresent scope. The seriesPresent scope should be constrained to the scope of a scanJob, since this is keyed to given series.	12 years ago
Matt T. Proud	fe41ce0b19	Conditionalize disk initializations. This commit conditionalizes the creation of the diskFrontier and seriesFrontier along with the iterator such that they are provisioned once something is actually required from disk.	12 years ago
juliusv	97736a030a	Merge pull request #277 from prometheus/feature/exporter-prefix Prepend "exporter_" to labels that already exist in exported metrics.	12 years ago
Julius Volz	dcfd09c801	Prepend "exporter_" to labels that already exist in exported metrics. If the metrics exported by a process already contain any of a target's base labels (such as "job" or "instance", but also any manually assigned target-group label), don't overwrite that label, but instead add a new label consisting of the original label name prepended with "exporter_". This is to accomodate intermediate exporter jobs, which might indicate e.g. the jobs and instances for which they are exporting data.	12 years ago
juliusv	d828b9c835	Merge pull request #276 from prometheus/fix/delta-noncounter-resets Fix handling of negative deltas for non-counter values.	12 years ago
Julius Volz	138334fb31	Fix handling of negative deltas for non-counter values.	12 years ago
Julius Volz	a8468a2e5e	Fix reversed disk flush cutoff behavior.	12 years ago
Julius Volz	eb1f956909	Revert "Revert "Ensure that all extracted samples are added to view."" This reverts commit `4b30fb86b4`.	12 years ago
juliusv	03addcd1a7	Merge pull request #273 from prometheus/fix/delta-handling Fix handling of empty ranges in delta	12 years ago
Julius Volz	66d4620061	Don't assume delta has at least one sample per vector element.	12 years ago
Julius Volz	21c3be0814	Skip any empty range/boundary elements, not only nil ones.	12 years ago
Matt T. Proud	20d49ea169	Merge pull request #272 from prometheus/feature/status/uptime Include uptime in the status console.	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	c10780c966	Introduce telemetry for rule evaluator durations. This commit adds telemetry for the Prometheus expression rule evaluator, which will enable meta-Prometheus monitoring of customers to ensure that no instance is falling behind in answering routine queries. A few other sundry simplifications are introduced, too.	12 years ago
Johannes 'fish' Ziemke	8507c58bf2	Fix filename in Makefile.	12 years ago
Matt T. Proud	fe5c70fc61	Merge pull request #270 from prometheus/fix/expression/index-error Revert "Ensure that all extracted samples are added to view."	12 years ago
Matt T. Proud	4b30fb86b4	Revert "Ensure that all extracted samples are added to view." This reverts commit `008314b5a8`. By running an automated git bisection described in https://gist.github.com/matttproud-soundcloud/22a371a8d2cba382ea64 this commit was found.	12 years ago
Matt T. Proud	9553971239	Merge pull request #267 from prometheus/fix/delta-boundaries Use GetBoundaryValues() for non-counter deltas.	12 years ago
Julius Volz	750f862d9a	Use GetBoundaryValues() for non-counter deltas.	12 years ago
juliusv	cc07b9ce74	Merge pull request #268 from prometheus/fix/value-extraction Interval value extraction fixes and optimizations.	12 years ago
Julius Volz	f2b48b8c4a	Make getValuesAtIntervalOp consume all chunk data in one pass. This is mainly a small performance improvement, since we skip past the last extracted time immediately if it was also the last sample in the chunk, instead of trying to extract non-existent values before the chunk end again and again and only gradually approaching the end of the chunk.	12 years ago
Julius Volz	83d60bed89	extractValuesAroundTime() code simplification.	12 years ago
Julius Volz	008314b5a8	Ensure that all extracted samples are added to view. The current behavior only adds those samples to the view that are extracted by the last pass of the last processed op and throws other ones away. This is a bug. We need to append all samples that are extracted by each op pass. This also makes view.appendSamples() take an array of samples.	12 years ago
Matt T. Proud	556be84c73	Merge pull request #265 from prometheus/feature/memory-arena-simplification Move In-Memory Arena Away from Skiplist	12 years ago
