bwplotka	9385f31147	scrape: Fix metadata in WAL not working for histograms and summaries. The was a bug (due to confusion?) on the local metadata cache that is cached by metric family not the series metric name. The fix is to NOT use that local cache at all (it's still needed for current metadata API implementation, added TODO on how we can get rid of it). I went ahead and also rename Metric field in metadata structs to MetricFamily to make clear it's not always __name__. Signed-off-by: bwplotka <bwplotka@gmail.com>	11 months ago
György Krajcsovits	482a7fd890	fix(remotewrite2): do not send uninitialized garbage if there's no metadata Found during testing for https://github.com/grafana/mimir/issues/9072 Debug printout showed: KRAJO: seriesName=cortex_request_duration_seconds_bucket, metricFamily=cortex_request_duration_seconds_bucket, type=GAUGE, help=cortex_bucket_index_load_duration_seconds_sum, unit= which is nonsense. I can imagine more cases where this is the case and makes actual sense. Some targets might miss metadata and if there's a pipeline that loses it.

György Krajcsovits	594b882e8b	fix(remotewrite2): do not overwrite help text with unit in enqueue While testing POC for https://github.com/grafana/mimir/issues/9072 I saw no unit or help metadata. Our test env: https://github.com/grafana/mimir/tree/main/development/mimir-monolithic-mode doesn't have units, so that was empty and cleared the help due to this bug.

sh0rez	5303e515af	remote/otlp: convert delta to cumulative (#15165 ) What Adds support for OTLP delta temporality to the OTLP endpoint. This is done by calling the deltatocumulative processor from the OpenTelemetry collector during OTLP conversion. Why Delta conversion is a naturally stateful process, which requires careful request routing when operated inside a collector. Prometheus is already stateful and doing the conversion in-server reduces the operational burden on the ingest architecture by only having one stateful component. How deltatocumulative is a OTel collector component that works as follows: * pmetric.Metrics come from a receiver or in this case from the HTTP client * It operates as an in-place update loop: * for each sample, if not delta, leave unmodified * if delta, do: * state += sample, where state is the in-memory sum of all previous samples * sample = state, sample value is now cumulative * this is supported for sums (counters), gauges, histograms (old histograms) and exponential histograms (native histograms) If a series receives no new samples for 5m, its state is removed from memory Performance Delta performance is a stateful operation and the OTel code is not highly optimized yet, e.g. it locks the entire processor for each request. Nonetheless, care has been taken to mitigate those effects: delta conversion is behind a feature flag. If disabled, no conversion code is ever invoked if enabled, conversion is not invoked if request not actually contains delta samples. This leads to no measureable performance difference between default-cumulative to convert-cumulative (only cumulative, feature on/off) Signed-off-by: sh0rez <me@shorez.de>	12 months ago

Arthur Silva Sens	5fdec31401	otlp/translator: Use separate function for metric names with UTF8 characters (#15664 ) BuildCompliantName was renamed to BuildCompliantMetricName, and it no longer takes UTF8 support into consideration. It focuses on building a metric name that follows Prometheus conventions. A new function, BuildMetricName, was added to optionally add unit and type suffixes to OTLP metric names without translating any characters to underscores(_).	12 months ago

Đurica Yuri Nikolić	101b1c307f	[ENHANCEMEN] Remote-Write: optionally use a DNS resolver that picks a random IP (#15329 ) When a remote-write is executed towards a host name that is resolved to multiple IP addresses, this PR introduces a possibility to force creation of new connections used for the remote-write request to a randomly chosen IP address from the ones corresponding to the host name. The default behavior remains unchanged, i.s., the IP address used for the connection creation remains the one chosen by Go. This is an experimental feature, it is disabled by default.
