SuperQ	a3dd323a53	Make regex-matching docs more obvious Split out the note about regex-matching into a separate paragraph to make it more obvious. Move it up, closer to the definition. Signed-off-by: SuperQ <superq@gmail.com>	4 years ago
beorn7	b39f2739e5	PromQL: Always enable negative offset and @ modifier This follows the line of argument that the invariant of not looking ahead of the query time was merely emerging behavior and not a documented stable feature. Any query that looks ahead of the query time was simply invalid before the introduction of the negative offset and the @ modifier. Signed-off-by: beorn7 <beorn@grafana.com>	4 years ago
Ganesh Vernekar	095f572d4a	Sync sparsehistogram branch with main (#9189 ) * Fix `kuma_sd` targetgroup reporting (#9157) * Bundle all xDS targets into a single group Signed-off-by: austin ce <austin.cawley@gmail.com> * Snapshot in-memory chunks on shutdown for faster restarts (#7229) Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Rename links Signed-off-by: Levi Harrison <git@leviharrison.dev> * Remove Individual Data Type Caps in Per-shard Buffering for Remote Write (#8921) * Moved everything to nPending buffer Signed-off-by: Levi Harrison <git@leviharrison.dev> * Simplify exemplar capacity addition Signed-off-by: Levi Harrison <git@leviharrison.dev> * Added pre-allocation Signed-off-by: Levi Harrison <git@leviharrison.dev> * Don't allocate if not sending exemplars Signed-off-by: Levi Harrison <git@leviharrison.dev> * Avoid deadlock when processing duplicate series record (#9170) * Avoid deadlock when processing duplicate series record `processWALSamples()` needs to be able to send on its output channel before it can read the input channel, so reads to allow this in case the output channel is full. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * processWALSamples: update comment Previous text seems to relate to an earlier implementation. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Optimise WAL loading by removing extra map and caching min-time (#9160) * BenchmarkLoadWAL: close WAL after use So that goroutines are stopped and resources released Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * BenchmarkLoadWAL: make series IDs co-prime with #workers Series are distributed across workers by taking the modulus of the ID with the number of workers, so multiples of 100 are a poor choice. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * BenchmarkLoadWAL: simulate mmapped chunks Real Prometheus cuts chunks every 120 samples, then skips those samples when re-reading the WAL. Simulate this by creating a single mapped chunk for each series, since the max time is all the reader looks at. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Fix comment Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Remove series map from processWALSamples() The locks that is commented to reduce contention in are now sharded 32,000 ways, so won't be contended. Removing the map saves memory and goes just as fast. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * loadWAL: Cache the last mmapped chunk time So we can skip calling append() for samples it will reject. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Improvements from code review Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Full stops and capitals on comments Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Cache max time in both places mmappedChunks is updated Including refactor to extract function `setMMappedChunks`, to reduce code duplication. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Update head min/max time when mmapped chunks added This ensures we have the correct values if no WAL samples are added for that series. Note that `mSeries.maxTime()` was always `math.MinInt64` before, since that function doesn't consider mmapped chunks. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Split Go and React Tests (#8897) * Added go-ci and react-ci Co-authored-by: Julien Pivotto <roidelapluie@inuits.eu> Signed-off-by: Levi Harrison <git@leviharrison.dev> * Remove search keymap from new expression editor (#9184) Signed-off-by: Julius Volz <julius.volz@gmail.com> Co-authored-by: Austin Cawley-Edwards <austin.cawley@gmail.com> Co-authored-by: Levi Harrison <git@leviharrison.dev> Co-authored-by: Julien Pivotto <roidelapluie@inuits.eu> Co-authored-by: Bryan Boreham <bjboreham@gmail.com> Co-authored-by: Julius Volz <julius.volz@gmail.com>	4 years ago

Ganesh Vernekar	9199fcb8d1	'@ <timestamp>' modifier (#8121 ) This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit. An example query: ``` rate(process_cpu_seconds_total[1m]) and topk(7, rate(process_cpu_seconds_total[1h] @ 1234)) ``` which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.
