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	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
Julius Volz	8586c7520c	Support negative graph values. Currently graph Y-Axes were hardcoded to start at 0. Choose the Y-scale automatically based on the graph data instead.	12 years ago
Julius Volz	081191afb8	Remember and display last scrape errors in web UI.	12 years ago
Matt T. Proud	1a95406b81	Include forgotten databases.html.	12 years ago
Matt T. Proud	b224251981	Simplify compaction and expose database sizes. This commit simplifies the way that compactions across a database's keyspace occur due to reading the LevelDB internals. Secondarily it introduces the database size estimation mechanisms. Include database health and help interfaces. Add database statistics; remove status goroutines. This commit kills the use of Go routines to expose status throughout the web components of Prometheus. It also dumps raw LevelDB status on a separate /databases endpoint.	12 years ago
Bernerd Schaefer	cdde766f39	Embed mutex on web status handler	12 years ago
Bernerd Schaefer	7740167654	Add comments about potential race conditions	12 years ago
Bernerd Schaefer	9183302b1f	Web handler returns 404 for favicon requests	12 years ago
Matt Proud	7f0d816574	Schedule the background compactors to run. This commit introduces three background compactors, which compact sparse samples together. 1. Older than five minutes is grouped together into chunks of 50 every 30 minutes. 2. Older than 60 minutes is grouped together into chunks of 250 every 50 minutes. 3. Older than one day is grouped together into chunks of 5000 every 70 minutes.	12 years ago
Julius Volz	af7920126c	Fix build errors and add default build step to "make".	12 years ago
Julius Volz	56324d8ce2	Make AST query storage non-global.	12 years ago
Matt T. Proud	3b9b1c6ab4	Define dependencies for web. stack concretely. This commit destroys the use of AppState, which makes passing concrete state along to various serving components onerous.	12 years ago
Julius Volz	04e661c28f	Move build info to the top of the status HUD.	12 years ago
Julius Volz	f3cf8eae7e	Restyle navigation a bit, align content elements with it.	12 years ago
Johannes 'fish' Ziemke	c5e507cd9c	Never submit empty queries.	12 years ago
Johannes 'fish' Ziemke	ba289ef7cd	Add the console to the main/graph ui.	12 years ago
Julius Volz	9cea5d9df8	Convert the Prometheus configuration to protocol buffers.	12 years ago
Matt T. Proud	3362bf36e2	Include curator status in web heads-up-display.	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	169ed9d297	Ignore web/static/generated and build/root/share	12 years ago
Bernerd Schaefer	4faf16787d	Move `-f` option to `cp` to command start `cp file -f file` fails on OS X.	12 years ago
Matt T. Proud	961ff26874	Fix positional flags for ``cp`` on Darwin. Unfortunately ``cp`` on Darwin regards some flags as positional and requires them to be in a specific place. The new Protocol Buffer descriptor bundling fails on Mac OS.	12 years ago
Bernerd Schaefer	45243ac2da	Print flags on status page.	12 years ago
Bernerd Schaefer	862054e88b	web.StartServing prints listening address	12 years ago
Bernerd Schaefer	a2a4f94aae	StatusHandler renders build info	12 years ago
Johannes 'fish' Ziemke	1f96d4c822	Move protobuf descriptor and add content-type. - move to static/generated - set content-type based on extension '.description'	12 years ago
Matt T. Proud	9e02c2393a	Include generated Protocol Buffer descriptor. The Protocol Buffer compiler supports generating a machine-readable descriptor file encoded as a provided Protocol Buffer message type, which can be used to decode messages that have been encoded with it after-the-fact. The generated descriptor also bundles in dependent message types. We can use this to perform forensics on old Prometheus clients, if necessary.	12 years ago
Matt T. Proud	e86f4d9dfd	Convert time readers to represent time in UTC. Go's time.Time represents time as UTC in its fundamental data type. That said, when using ``time.Unix(...)``, it sets the zone for the time representation to the local. Unfortunately with diagnosis and our tests, it is a PITA to jump between various zones, even though the serialized version remains the same. To keep things easy, all places where times are generated or read are converted into UTC. These conversions are cheap, for ``Time.In`` merely changes a pointer reference in the struct, nothing more. This enables me to diagnose test failures with fixture data very easily.	12 years ago
Julius Volz	a2623efcdf	Register pprof /debug endpoints with custom HTTP mux.	12 years ago
Johannes 'fish' Ziemke	712bf5e2f9	Add per graph auto-refresh option to web UI. This adds a drop-down menu to select/disable a auto-refresh interval.	12 years ago
Julius Volz	a0d311c9e6	Constantize job name label.	12 years ago
Bernerd Schaefer	72bd585485	Revert style change to legend items	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
Bernerd Schaefer	8af0bbb3a0	Set job label for targets registered through the API This is set when jobs are statically registered (see retrieval/targetmanager.go#L92), and should be set here, too.	12 years ago

Bernerd Schaefer	a7ec43189a	Hovering over legend items highlights series in graph	12 years ago
Bernerd Schaefer	564633ecbc	Render graph labels vertically This helps to make the timeseries with many labels fit on the screen.	12 years ago
Bernerd Schaefer	5e9447996b	Set CORS Headers on API requests By setting Access-Control headers, the Prometheus metrics API can be accessed by cross-origin javascript applications (e.g., an external dashboard pulling Prometheus metrics).	12 years ago
Johannes 'fish' Ziemke	8fba639706	Fix path to expression browser js.	12 years ago
