Tony Lee	7cd56f56df	add queue_time slice to query_duration_seconds (#4050)	8 years ago

Nikunj Aggarwal	998dfcbac6	Expose itemtype outside the package (#3933)	8 years ago
Fabian Reinartz	7ccd4b39b8	*: implement query params ... This adds a parameter to the storage selection interface which allows query engine(s) to pass information about the operations surrounding a data selection. This can for example be used by remote storage backends to infer the correct downsampling aggregates that need to be provided.	8 years ago

Fabian Reinartz	83cd270ea4	*: adapt to storage interface changes	8 years ago
David Kaltschmidt	87c46ea6c3	Renamed TotalEvalTime to EvalTotalTime ... * TotalFoo suggested a comprehensive timing, but TotalEvalTime was part of the Exec timings, together with Queue timings * The other option was to rename ExecTotalTime to TotalExecTime, but there was already ExecQueueTime, suggesting Exec to be some sort of group	8 years ago
David Kaltschmidt	c93e54d240	Adds execution timer stats to the range query ... API consumers should be able to get insight into the query run times. The UI currently measures total roundtrip times. This PR allows for more fine grained metrics to be exposed. * adds new timer for total execution time (queue + eval) * expose new timer, queue timer, and eval timer in stats field of the range query response: ```json { "status": "success", "data": { "resultType": "matrix", "result": [], "stats": { "execQueueTimeNs": 4683, "execTotalTimeNs": 2086587, "totalEvalTimeNs": 2077851 } } } ``` * stats field is optional, only set when query parameter `stats` is not empty Try it via ```sh curl 'http://localhost:9090/api/v1/query_range?query=up&start=1486480279&end=1486483879&step=14000&stats=true' ``` Review feedback * moved query stats json generation to query_stats.go * use seconds for all query timers * expose all timers available * Changed ExecTotalTime string representation from Exec queue total time to Exec total time	8 years ago
Brian Brazil	99905f82a6	Remove keep_common modifier. ... See #3060	8 years ago
Brian Brazil	67274f0794	Remove 4 interval staleness heuristic. (#3244) ... This means that if there is no stale marker, only the usual staleness delta (5m) applies. It has occured to me that there is an oddity in the heurestic. It works fine as long as you have 2 points within the last 5m, but breaks down when the time window advances to the point where you have just 1 point. Consider you had points at t=0 and t=10. With the heurestic it goes stale at t=51, up until t=300. However from t=301 until t=310 we only see the t=10 point and the series comes back to life. That is not desirable. I don't see a way to keep this form of heurestic working given this issue, so thus I'm removing it.	8 years ago
Julius Volz	f7e8348a88	Re-add contexts to storage.Storage.Querier() (#3230) ... * Re-add contexts to storage.Storage.Querier() These are needed when replacing the storage by a multi-tenant implementation where the tenant is stored in the context. The 1.x query interfaces already had contexts, but they got lost in 2.x. * Convert promql.Engine to use native contexts	8 years ago

Brian Brazil	220e78b9c3	Consider a series stale after 4.1 intervals with no data. ... To cover the cases where stale markers may not be available, we need to infer the interval and mark series stale based on that. As we're lacking stale markers this is less accurate, however it should be good enough for these cases. We need 4 intervals as if say we had data at t=0 and t=10, coming via federation. The next data point should be at t=20 however it could take up to t=30 for it actually to be ingested, t=40 for it to be scraped via federation and t=50 for it to be ingested. We then add 10% on to that for slack, as we do elsewhere.	9 years ago

Brian Brazil	80b40e6d91	Add initial staleness handing to promql. ... For instant vectors, if "stale" is the newest sample ignore the timeseries. For range vectors, filter out "stale" samples. Make it possible to inject "stale" samples in promql tests.	9 years ago
Brian Brazil	fcc88f0e1e	query/query_range should return eval timestamp ... Query and query_range should return the timestamp at which an evaluation is performed, not the timestamp of the data. This is as that's what query range asked for, and we need to keep query consistent with that. Query for a matrix remains unchanged, returning the literal matrix.	9 years ago
Brian Brazil	517b81f927	Add timestamp() function. ... Make the timestamp of instant vectors be the timestamp of the sample rather than the evaluation. We were not using this anywhere, so this is safe. Add a function to return the timestamp of samples in an instant vector. Fixes #1557	9 years ago
Tom Wilkie	4d9b917d11	Instrument Prometheus with OpenTracing (#2554) ... * Use request.Context() instead of a global map of contexts. * Add some basic opentracing instrumentation on the query path. * Remove tracehandler endpoint.	9 years ago
