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.	11 years ago

Julius Volz	9a4ca68a61	Add metrics for rule evaluation failures. Fixes https://github.com/prometheus/prometheus/issues/417	11 years ago
Julius Volz	c9618d11e8	Introduce copy-on-write for metrics in AST. This depends on changes in: https://github.com/prometheus/client_golang/tree/cow-metrics. Change-Id: I80b94833a60ddf954c7cd92fd2cfbebd8dd46142	11 years ago
Bjoern Rabenstein	b1e4956142	Apply a giant code cleanup. Essentially: - Remove unused code. - Make it 'go vet' clean. The only remaining warnings are in generated code. - Make it 'golint' clean. The only remaining warnings are in gerenated code. - Smoothed out same minor things. Change-Id: I3fe5c1fbead27b0e7a9c247fee2f5a45bc2d42c6	11 years ago
Julius Volz	6eecee55b7	Fix acronym caps in GeneratorURL. Change-Id: Ib18c1f617dcde1039e848059545a6d8831d9bf66	11 years ago
Bjoern Rabenstein	74c143c4c9	Improve scraper shutdown time. - Stop target pools in parallel. - Stop individual scrapers in goroutines, too. - Timing tweaks. Change-Id: I9dff1ee18616694f14b04408eaf1625d0f989696	11 years ago
Bjoern Rabenstein	b3ed9aa7a2	Clean up start-up and shut-down. Change-Id: Idff4bbb0a15a9f879bfbb3da5b1025179cab5e2c	11 years ago
Bjoern Rabenstein	f5f9f3514a	Major code cleanup. - Make it go-vet and golint clean. - Add comments, TODOs, etc. Change-Id: If1392d96f3d5b4cdde597b10c8dff1769fcfabe2	11 years ago

Bjoern Rabenstein	1909686789	Make metrics exported by the Prometheus server itself more consistent. - Always spell out the time unit (e.g. milliseconds instead of ms). - Remove "_total" from the names of metrics that are not counters. - Make use of the "Namespace" and "Subsystem" fields in the options. - Removed the "capacity" facet from all metrics about channels/queues. These are all fixed via command line flags and will never change during the runtime of a process. Also, they should not be part of the same metric family. I have added separate metrics for the capacity of queues as convenience. (They will never change and are only set once.) - I left "metric_disk_latency_microseconds" unchanged, although that metric measures the latency of the storage device, even if it is not a spinning disk. "SSD" is read by many as "solid state disk", so it's not too far off. (It should be "solid state drive", of course, but "metric_drive_latency_microseconds" is probably confusing.) - Brian suggested to not mix "failure" and "success" outcome in the same metric family (distinguished by labels). For now, I left it as it is. We are touching some bigger issue here, especially as other parts in the Prometheus ecosystem are following the same principle. We still need to come to terms here and then change things consistently everywhere. Change-Id: If799458b450d18f78500f05990301c12525197d3	11 years ago
Brian Brazil	f525ca5d9e	Let consoles get graph links from experssions. Rename ConsoleLinkFromExpression, as we now have consoles. Change-Id: I7ed2c9c83863adb390b51121dd9736845f7bcdfc	11 years ago
Bjoern Rabenstein	8956faeccb	Migrate to new client_golang. This change will only be submitted when the new client_golang has been moved to the new version. Change-Id: Ifceb59333072a08286a8ac910709a8ba2e3a1581	11 years ago
Brian Brazil	960ede66dc	Use html/template for console templates and add template libary support. Add a function to bypass the new auto-escaping. Add a function to workaround go's templates only allowing passing in one argument. Change-Id: Id7aa3f95e7c227692dc22108388b1d9b1e2eec99	11 years ago
