Julius Volz	cb816ea14a	Improve timestamp/duration parsing in query API. Don't handle `0` as a special timestamp value for "now" anymore, except in the `QueryRange()` case, where existing API consumers still expect `0` to mean "now". Also, properly return errors now for malformed timestamp/duration float values.	10 years ago

beorn7	fa1935a644	Remove /api/targets call and do not show job and instance labels on status. /api/targets was undocumented and never used and also broken. Showing instance and job labels on the status page (next to targets) does not make sense as those labels are set in an obvious way. Also add a doc comment to TargetStateToClass.	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

Julius Volz	b3978fe869	Fix Rickshaw/D3 version mismatch. When Rickshaw was updated to 1.5.1 in `fd43daf82e`, the Rickshaw upstream package now contained 3 different D3 files: d3.min.js d3.v2.js d3.v3.js For details on why that is, see https://groups.google.com/forum/#!topic/d3-js/lXQgKA7mtEw For the 1.5.1 Rickshaw to work properly (being able to format dates with D3 without causing a JS error), it needs d3.v2.js or d3.v3.js, not the d3.min.js one. I chose to update us to d3.v3.js now, since that is the most recent and minified version, and I didn't see any problems with it (also, the current Rickshaw examples are using that D3 version). Currently, displaying graphs with a range >14d is broken. This fixes that.	10 years ago
Bjoern Rabenstein	f568bbc19f	Improve comments about embedding.	10 years ago
Tobias Schmidt	edadba3b25	Merge web/blob/Makefile into web/Makefile While the recent commit `7e5745f` solved the issue of having an independent blob-stamp file, which was possible to become out of sync with the necessary web/blob/files.go file, this change further simplifies the setup by merging the two Makefile. The only purpose of web/Makefile was to call targets in web/blob/Makefile. As all dependencies for blob/files.go are outside of the blob/ directory, the separation isn't logically necessary.	10 years ago

Julius Volz	d4374a9265	More efficient JSON query result format. This depends on https://github.com/prometheus/client_golang/pull/51. For vectors, the result format looks like this: ```json { "version": 1, "type" : "vector", "value" : [ { "timestamp" : 1421765411.045, "value" : "65.475000", "metric" : { "quantile" : "0.5", "instance" : "http://localhost:9090/metrics", "job" : "prometheus", "__name__" : "http_request_duration_microseconds", "handler" : "/static/", "method" : "get", "code" : "304" } }, { "timestamp" : 1421765411.045, "value" : "5826.339000", "metric" : { "quantile" : "0.9", "instance" : "http://localhost:9090/metrics", "job" : "prometheus", "__name__" : "http_request_duration_microseconds", "handler" : "prometheus", "method" : "get", "code" : "200" } }, /* ... / ] } ``` For matrices, it looks like this: ```json { "version": 1, "type" : "matrix", "value" : [ { "metric" : { "quantile" : "0.99", "instance" : "http://localhost:9090/metrics", "job" : "prometheus", "__name__" : "http_request_duration_microseconds", "handler" : "/static/", "method" : "get", "code" : "200" }, "values" : [ [ 1421765547.659, "29162.953000" ], [ 1421765548.659, "29162.953000" ], [ 1421765549.659, "29162.953000" ], / ... */ ] } ] } ```	10 years ago

Julius Volz	3d47f94149	Drop metric names after transformations. After many transformations, it doesn't make sense to keep the metric names, since the result of the transformation is no longer that metric. This drops the metric name after such transformations and makes the web UI deal well with missing metric names. This depends on the current branch on the following things: - prometheus/client_golang needs to be at `e237cf15c6` in branch "julius/int-fingerprints" (to be merged with new storage) - prometheus/promdash needs to be at `dd7691c9c2` Change-Id: Ib3c8cad8d647d9854e8c653c424b8c235ccc231d	10 years ago

Julius Volz	21cafe6cd7	Only evict memory series after they are on disk. This fixes the problem where samples become temporarily unavailable for queries while they are being flushed to disk. Although the entire flushing code could use some major refactoring, I'm explicitly trying to do the minimal change to fix the problem since there's a whole new storage implementation in the pipeline.

Brian Brazil	e27447da5c	Remove the broken "User Dashboard" link. Due to the lack of a </a>, this makes the entire header render badly. Accordingly it's safe to assume noone is using it, so remove it. With the new console template support, we'll need to something a bit more nuanced later. Change-Id: I3424bed6aea18cbd4c63ad48f98808098dadc3ad	10 years ago

Brian Brazil	e041c0cd46	Add console and alert templates with access to all data. Move rulemanager to it's own package to break cicrular dependency. Make NewTestTieredStorage available to tests, remove duplication. Change-Id: I33b321245a44aa727bfc3614a7c9ae5005b34e03	11 years ago
Julius Volz	01f652cb4c	Separate storage implementation from interfaces. This was initially motivated by wanting to distribute the rule checker tool under `tools/rule_checker`. However, this was not possible without also distributing the LevelDB dynamic libraries because the tool transitively depended on Levigo: rule checker -> query layer -> tiered storage layer -> leveldb This change separates external storage interfaces from the implementation (tiered storage, leveldb storage, memory storage) by putting them into separate packages: - storage/metric: public, implementation-agnostic interfaces - storage/metric/tiered: tiered storage implementation, including memory and LevelDB storage. I initially also considered splitting up the implementation into separate packages for tiered storage, memory storage, and LevelDB storage, but these are currently so intertwined that it would be another major project in itself. The query layers and most other parts of Prometheus now have notion of the storage implementation anymore and just use whatever implementation they get passed in via interfaces. The rule_checker is now a static binary :) Change-Id: I793bbf631a8648ca31790e7e772ecf9c2b92f7a0	11 years ago
Matt T. Proud	2064f32662	Clean up quitting behavior and add quit trigger. The closing of Prometheus now using a sync.Once wrapper to prevent any accidental multiple invocations of it, which could trigger corruption or a race condition. The shutdown process is made more verbose through logging. A not-enabled by default web handler has been provided to trigger a remote shutdown if requested for debugging purposes.

Julius Volz	cc04238a85	Switch to new "__name__" metric name label. This also fixes the compaction test, which before worked only because the input sample sorting was accidentally equal to the resulting on-disk sample sorting. Change-Id: I2a21c4b46ba562424b27058fc02eba84fa6a6006	11 years ago
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
Conor Hennessy	eba01d1119	Remove usage of gorest. Due to on going issues, we've decided to remove gorest. It started with gorest not being thread-safe (it does introspection to create a new handler which is an easy process to mess up with multiple threads of execution): https://code.google.com/p/gorest/issues/detail?id=15 While the issue has been marked fixed, it looks like the patch has introduced more problems than the original issue and simply doesn't work properly. I'm not sure the behaviour was thought through properly. If a new instance is needed every request then a handler-factory is needed or the library needs to set expectations about how the new objects should interact with their constructor state. While it was tempting to try out another routing library, I think for now it's better to use dumb vanilla Go routing. At least until we decide which URL format we intend to standardize on.

Matt T. Proud	4a87c002e8	Update low-level i'faces to reflect wireformats.
