Julius Volz	740d448983	Use custom timestamp type for sample timestamps and related code. So far we've been using Go's native time.Time for anything related to sample timestamps. Since the range of time.Time is much bigger than what we need, this has created two problems: - there could be time.Time values which were out of the range/precision of the time type that we persist to disk, therefore causing incorrectly ordered keys. One bug caused by this was: https://github.com/prometheus/prometheus/issues/367 It would be good to use a timestamp type that's more closely aligned with what the underlying storage supports. - sizeof(time.Time) is 192, while Prometheus should be ok with a single 64-bit Unix timestamp (possibly even a 32-bit one). Since we store samples in large numbers, this seriously affects memory usage. Furthermore, copying/working with the data will be faster if it's smaller. MEMORY USAGE RESULTS Initial memory usage comparisons for a running Prometheus with 1 timeseries and 100,000 samples show roughly a 13% decrease in total (VIRT) memory usage. In my tests, this advantage for some reason decreased a bit the more samples the timeseries had (to 5-7% for millions of samples). This I can't fully explain, but perhaps garbage collection issues were involved. WHEN TO USE THE NEW TIMESTAMP TYPE The new clientmodel.Timestamp type should be used whenever time calculations are either directly or indirectly related to sample timestamps. For example: - the timestamp of a sample itself - all kinds of watermarks - anything that may become or is compared to a sample timestamp (like the timestamp passed into Target.Scrape()). When to still use time.Time: - for measuring durations/times not related to sample timestamps, like duration telemetry exporting, timers that indicate how frequently to execute some action, etc. NOTE ON OPERATOR OPTIMIZATION TESTS We don't use operator optimization code anymore, but it still lives in the code as dead code. It still has tests, but I couldn't get all of them to pass with the new timestamp format. I commented out the failing cases for now, but we should probably remove the dead code soon. I just didn't want to do that in the same change as this. Change-Id: I821787414b0debe85c9fffaeb57abd453727af0f	11 years ago
Johannes 'fish' Ziemke	8c08a5031f	Add search domain support to SRV lookups This adds search domain support by trying to resolve a name by appending each search domain configured in /etc/resolv.conf until the query succeeds (NOERROR) and has at least one answer.

Julius Volz	aa5d251f8d	Use github.com/golang/glog for all logging.	11 years ago
Matt T. Proud	a5141e4d0a	Depointerize storage conf. and chain ingester. The storage builders need to work with the assumption that they have a copy of the underlying configuration data if any mutations are made.	11 years ago
Julius Volz	f8b20f30ac	Make retrieval work with client's new Ingester interface.	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

Matt T. Proud	06b4a40661	Represent targets in a tabular interface. This commit represents a target group's endpoints in a tabular fashion for better differentiation of their state in a concise manner.	12 years ago
Matt T. Proud	e20e6980e9	Completely extract response payload for decoding. This commit forces the extraction framework to read the entire response payload into a buffer before attempting to decode it, for the underlying Protocol Buffer message readers do not block on partial messages.	12 years ago
Julius Volz	9a48f57b66	Continue scraping old targets on SD fail. When we have trouble resolving the targets for a job via service discovery, we shouldn't just stop scraping the targets we currently have.	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
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
Julius Volz	081191afb8	Remember and display last scrape errors in web UI.	12 years ago
Matt T. Proud	8f4c7ece92	Destroy naked returns in half of corpus. The use of naked return values is frowned upon. This is the first of two bulk updates to remove them.	12 years ago
Bernerd Schaefer	428d91c86f	Rename test helper files to helpers_test.go This ensures that these files are properly included only in testing.	12 years ago
Matt T. Proud	244a4a9cdb	Update to go1.1. This commit updates the documentation, Makefiles, formatting, and code semantics to support the 1.1. runtime, which includes ... 1. ``make advice``, 2. ``make format``, and 3. ``go fix`` on various targets.	12 years ago

Bernerd Schaefer	3929582892	Target uses HTTP transport with deadlines Instead of externally handling timeouts when scraping a target, we set timeouts on the HTTP connection. This ensures that we don't leak goroutines on timeouts. [fixes #181]	12 years ago
Matt T. Proud	a48ab34dd0	Refresh Prometheus client API usage. The client API has been updated per https://github.com/prometheus/client_golang/pull/9.	12 years ago
Bernerd Schaefer	cf3e6ae084	Add LabelSet helper to fix go 1.0.3 build	12 years ago
Bernerd Schaefer	dfd5c9ce28	Refactor processor for 0.0.2 schema Primary changes: * Strictly typed unmarshalling of metric values * Schema types are contained by the processor (no "type entity002") Minor changes: * Added ProcessorFunc type for expressing processors as simple functions. * Added non-destructive `Merge` method to `model.LabelSet`	12 years ago
Bernerd Schaefer	7c3e04c546	Add version 0.0.2 processor	12 years ago
Bernerd Schaefer	76731c80c6	Use Content-Type data for telemetry versioning ProcessorForRequestHeader now looks first for a header like `Content-Type: application/json; schema="prometheus/telemetry"; version="0.0.1"` before falling back to checking `X-Prometheus-API-Version`.	12 years ago
Julius Volz	d4ff85db5a	Add instance label to health (up) timeseries.	12 years ago
Matt T. Proud	f9e99bd08a	Refresh SampleValue to 64-bit floating point. We always knew that this needed to be fixed.	12 years ago

Julius Volz	8c9e9632a8	Record scrape health timeseries per target.	12 years ago
Julius Volz	a0d311c9e6	Constantize job name label.	12 years ago
Julius Volz	a1ba23038e	Fix scrape timestamps to reduce sample time jitter. We're currently timestamping samples with the time at the end of a scrape iteration. It makes more sense to use a timestamp from the beginning of the scrape for two reasons: a) this time is more relevant to the scraped values than the time at the end of the HTTP-GET + JSON decoding work. b) it reduces sample timestamp jitter if we measure at the beginning, and not at the completion of a scrape.	12 years ago
Johannes 'fish' Ziemke	14407a076a	Convert addresses pointing to localhost in status. Until now, targets pointing to localhost in the status view are linked to localhost, so you can't follow those links by clicking on them. This change converts the links to point to the hostname of the prometheus server. Before: <a href="http://localhost:9090/metrics.json">http://localhost:9090/metrics.json</a> After: <a href="http://hostname-of-prometheus-server:9090/metrics.json">http://localhost:9090/metrics.json</a>	12 years ago
Julius Volz	2b8f0b2cc7	Constantize metric name label name.	12 years ago
Matt T. Proud	5a9417f80a	Include humanized target state strings. In the current /status implementation, we cannot divine what the target's state is but rather get an integer constant for it. This commit, stringifies the constants.	12 years ago
Julius Volz	f1fc7d717a	Allow replacing job targets via HTTP API. This roughly comprises the following changes: - index target pools by job instead of scrape interval - make targets within a pool exchangable while preserving existing health state for targets - allow exchanging targets via HTTP API (PUT) - show target lists in /status (experimental, for own debug use)	12 years ago
Julius Volz	047eb219e4	Fix target health state update. Right now, futureState is only used to give hints to the health scheduler, but nowhere is this future state persisted into the target's state field, so we don't actually track a target's state over time.	12 years ago
Julius Volz	5d55785936	Fix broken target scrape error propagation.	12 years ago
Julius Volz	3537edee9f	Fix targetpool iteration deadlock.	12 years ago

Tobias Schmidt	53eab86a4f	Merge pull request #51 from prometheus/refactor/testability/update-to-time-provider Swap ``time.Now`` with testable ``Time.Now``.	12 years ago
Matt T. Proud	e01b6cdb44	Duration statistics for each target pool. We have an open question of how long does it take for each target pool to have the state retrieved from all participating elements. This commit starts by providing insight into this.	12 years ago
Matt T. Proud	4cd153555e	Swap ``time.Now`` with testable ``Time.Now``.	12 years ago
Matt T. Proud	ea54751431	Update import paths to new location. This repository moved from matttproud/prometheus to prometheus/prometheus, and all import paths need to be updated.	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	88d15373c5	Upgrade Prometheus to new API.	12 years ago
juliusv	39b2e72eb0	Merge pull request #37 from matttproud/julius-base-labels Add support for configured job base labels.	12 years ago
Julius Volz	6f937ee032	Add preliminary metric docstrings and empty base labels.	12 years ago
Julius Volz	80cdb0121d	Add support for configured job base labels.	12 years ago
Matt T. Proud	190e4e3fa3	``TargetManager`` and ``TargetPool`` ass pointers.	12 years ago
Matt T. Proud	9752f1e61d	Refactor Target as interface for testability. Future tests around the ``TargetPool`` and ``TargetManager`` and friends will be a lot easier when the concrete behaviors of ``Target`` can be extracted out. Plus, each ``Target``, I suspect, will have its own resolution and query strategy.	12 years ago
Matt T. Proud	9af0faaefb	Get ``TargetPool`` test working again.	12 years ago
Matt T. Proud	d772c6c2b5	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

Julius Volz	45a3e0a182	Rename Target Frequency -> Interval.	12 years ago
Matt T. Proud	7a9777b4b5	Create ``TargetPool`` priority queue. ``TargetPool`` is a pool of targets pending scraping. For now, it uses the ``heap.Interface`` from ``container/heap`` to provide a priority queue for the system to scrape from the next target. It is my supposition that we'll use a model whereby we create a ``TargetPool`` for each scrape interval, into which ``Target`` instances are registered.	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
