Julius Volz	4f79072fd1	Update common/route vendoring for contextFn errors	9 years ago
Julius Volz	f92532f254	api: Consolidate web API contexts ... This is based on the common/route changes in https://github.com/prometheus/common/pull/61.	9 years ago
Julius Volz	c187308366	storage: Contextify storage interfaces. ... This is based on https://github.com/prometheus/prometheus/pull/1997. This adds contexts to the relevant Storage methods and already passes PromQL's new per-query context into the storage's query methods. The immediate motivation supporting multi-tenancy in Frankenstein, but this could also be used by Prometheus's normal local storage to support cancellations and timeouts at some point.	9 years ago
Julius Volz	ed5a0f0abe	promql: Allow per-query contexts. ... For Weaveworks' Frankenstein, we need to support multitenancy. In Frankenstein, we initially solved this without modifying the promql package at all: we constructed a new promql.Engine for every query and injected a storage implementation into that engine which would be primed to only collect data for a given user. This is problematic to upstream, however. Prometheus assumes that there is only one engine: the query concurrency gate is part of the engine, and the engine contains one central cancellable context to shut down all queries. Also, creating a new engine for every query seems like overkill. Thus, we want to be able to pass per-query contexts into a single engine. This change gets rid of the promql.Engine's built-in base context and allows passing in a per-query context instead. Central cancellation of all queries is still possible by deriving all passed-in contexts from one central one, but this is now the responsibility of the caller. The central query context is now created in main() and passed into the relevant components (web handler / API, rule manager). In a next step, the per-query context would have to be passed to the storage implementation, so that the storage can implement multi-tenancy or other features based on the contextual information.	9 years ago
beorn7	39c4915401	federation: Collapse time series of the same name ... This will avoid duplicate MetricFamilies, thereby shrinking the size of the federation payload and also creating legal text format. Also, add unit tests for federation. They were also needed for the previous state of the code, but were missing.	9 years ago

Ali Reza	624717e801	Log HTTP server errors using common/log ... change naming to be more descriptive. Fixes #1651 remove pointer receiver use common/log error logger	10 years ago
beorn7	da8cb10b43	Partition the status tab into items in a dropdown ... I got feedback from different sources about rules and targets being too heavy in the status tab if their are lots of them. This change also allows for more fine-granular locking.	10 years ago

Fabian Reinartz	f2e359962c	Sort exported targets	10 years ago

Fabian Reinartz	9bbd9264e2	Add global labels to federation	11 years ago
Julius Volz	da2499d5a5	Add POST handler for /debug to fix CPU profiling. ... `go tool pprof` sends a POST request to enable CPU profiling, so we also need to handle that method.	11 years ago
Julius Volz	995d3b831d	Fix most golint warnings. ... This is with `golint -min_confidence=0.5`. I left several lint warnings untouched because they were either incorrect or I felt it was better not to change them at the moment.	11 years ago
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	11 years ago
Julius Volz	274e9d6955	Exit when web server encounters a startup error	11 years ago

Jan Berktold	2bf7048dbb	Add reload handler to web	11 years ago
Julius Volz	c5c7f92960	Fix /debug/pprof endpoint with new web router. ... This got broken in 78047326b4 since it stopped using the DefaultServeMux. This approach will defer pprof requests to the DefaultServeMux, which may or may not have pprof enabled (in Prometheus, it gets it included in main.go). An alternative approach would be to duplicate the four lines in https://golang.org/src/net/http/pprof/pprof.go#L62. When choosing that approach though, we would not automatically gain any new endpoints added by net/http/pprof or other /debug endpoints in the future.	11 years ago
Brian Brazil	7b5a29fc8f	web: Fix regression in .Path ... .Path is documented as removing /consoles/, recent changes added in a leading / which broke the provided console templates menu system.	11 years ago
Julius Volz	fcff35b43e	Consolidate external reachability flags into one. ... Besides fixing https://github.com/prometheus/prometheus/issues/805 by making the entire externally reachable server URL configurable, this adds tests for the "globalURL" template function and makes it easier to test other such functions in the future. This breaks the `web.Hostname` flag (and introduces `web.external-url`). This flag is likely only used by few users, so I hope that's justifiable. Fixes https://github.com/prometheus/prometheus/issues/805	11 years ago
Julius Volz	d7ea0397d4	Use templates.TemplateExpander for all page templates. ... This will allow us to use all of our shiny templating functions in the main page templates as well.	11 years ago
Fabian Reinartz	53b9d5917d	web: improve target URL handling and display.	11 years ago
Fabian Reinartz	39a8254963	web: add basic federation support. ... This commit adds a federation handler on /federate. It accepts `match[]` query parameters containing vector selectors. Their intersection determines the in-memory metrics that are returned in the same way as the /metrics endpoint does (modulo sorting).	11 years ago
Fabian Reinartz	119801027f	web: expose a version information endpoint	11 years ago
Fabian Reinartz	39edc2df7a	version: move version information into separate package. ... Version information is determined at build-time and thus there is no need to pass it down from main. In its own package it can be used from various other packages.	11 years ago
Fabian Reinartz	85d7c7640a	web: remove flags, refactor handlers	11 years ago
Sindre Myren	a081c9436b	Building without a Makefile (on Windows) ... Main changes: - Switched to using `go-bindata` in place of `scripts/embed-static.sh`. - Support for building Prometheus without a `Makefile`. - Minor typo fix to make Prometheus build on Windows (without Makefiles). Please note that this does not mean that prometheus will work on Windows. There are still failing tests!	11 years ago

Tobias Gesellchen	84d42f48e5	allow to override the default os.Hostname() when creating PrometheusURLs	11 years ago
Julius Volz	fcd33bbfd8	Improve web redirection and 404 behavior. ... Previously we redirected any non-existent path to the root (or path prefix). The new behavior: With no path prefix: - "" -> "/" - "/biz" -> 404 With path prefix of "/foo/bar": - "" -> "/foo/bar/" - "/" -> "/foo/bar/" - "/foo/bar" -> "/foo/bar/" - "/biz" -> /foo/bar/biz" (anything not starting with the path prefix gets the prefix prepended) - "/foo/bar/biz" -> 404	11 years ago
Julius Volz	267fd34156	Switch Prometheus to use github.com/prometheus/log. ... This change is conceptually very simple, although the diff is large. It switches logging from "github.com/golang/glog" to "github.com/prometheus/log", while not actually changing any log messages. V(1)-style logging has been changed to be log.Debug*().	11 years ago
