Julien Pivotto	bd9129117e	Target parameter labels should not be overridden by config params The following configuration snippet calls http://127.0.0.1:8000/?foo=value1 instead of http://127.0.0.1:8000/?foo=value2. This is incorrect, the labels of the target should be prefered. ```yaml - job_name: local params: foo: [value1] static_configs: - targets: ['127.0.0.1:8000'] labels: __param_foo: value2 ``` Signed-off-by: Julien Pivotto <roidelapluie@o11y.eu> Signed-off-by: Julien <roidelapluie@o11y.eu>	3 months ago

György Krajcsovits	0793a26d96	native histograms: only reduce resolution for exponential histograms Currently we can only reduce the resolution of exponential native histograms, so checking the schema for that is slightly more precise than checking against max schema.

Bryan Boreham	b987afa7ef	labels: simplify call to get Labels from Builder It took a `Labels` where the memory could be re-used, but in practice this hardly ever benefitted. Especially after converting `relabel.Process` to `relabel.ProcessBuilder`. Comparing the parameter to `nil` was a bug; `EmptyLabels` is not `nil` so the slice was reallocated multiple times by `append`. Lastly `Builder.Labels()` now estimates that the final size will depend on labels added and deleted. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	2fde2fb37d	scrape: add Target.LabelsRange This allows users of a Target to iterate labels without allocating heap memory. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	f4fd9b0d68	scrape: re-use memory in TargetsFromGroup Common service discovery mechanisms such as Kubernetes can generate a lot of target groups, so this function was allocating a lot of memory which then immediately became garbage.

Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Tom Wilkie	7369561305	Combine Appender.Add and AddFast into a single Append method. (#8489 ) This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends. This makes the API easier to consume and implement. In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

Bartlomiej Plotka	34426766d8	Unify Iterator interfaces. All point to storage now. This is part of https://github.com/prometheus/prometheus/pull/5882 that can be done to simplify things. All todos I added will be fixed in follow up PRs. * querier.Querier, querier.Appender, querier.SeriesSet, and querier.Series interfaces merged with storage interface.go. All imports that. * querier.SeriesIterator replaced by chunkenc.Iterator * Added chunkenc.Iterator.Seek method and tests for xor implementation (?) * Since we properly handle SelectParams for Select methods I adjusted min max based on that. This should help in terms of performance for queries with functions like offset. * added Seek to deletedIterator and test. * storage/tsdb was removed as it was only a unnecessary glue with incompatible structs. No logic was changed, only different source of abstractions, so no need for benchmarks. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago

gotjosh	05842176a6	Make the scrape.metricMetadataStore interface public To test the implementation of our metric metadata API, we need to represent various states of metadata in the scrape metadata store. That is currently not possible as the interface and method to set the store are private. This changes the interface, list and get methods, and the SetMetadaStore function to be public. Incidentally, the scrapeCache implementation needs to be renamed to match the new signature. Signed-off-by: gotjosh <josue@grafana.com>	5 years ago

xjewer	0d1a69353e	scrape: Add global jitter for HA server (#5181 ) * scrape: Add global jitter for HA server Covers issue in https://github.com/prometheus/prometheus/pull/4926#issuecomment-449039848 where the HA setup become a problem for targets unable to be scraped simultaneously. The new jitter per server relies on the hostname and external labels which necessarily to be uniq. As before, scrape offset will be calculated with regard the absolute time, so even restart/reload doesn't change scrape time per scrape target + prometheus instance. Use fqdn if possible, otherwise fall back to the hostname. It adds extra random seed to calculate server hash to be distinguish on machines with the same hostname, but different DC.
