Damien Grisonnet	e3b5416d05	model/textparse: improve error outputs Parsing errors in the Prometheus HTTP format parser are very hard to investigate since they only approximately indicate what is going wrong in the parser and don't provide any information about the incorrect input. As such it is very hard to tell what is wrong in the format exposed by the application. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com>	2 years ago

beorn7	c26891043f	textparse: Set CounterResetHint If a (float or integer) histogram is a gauge histogram, set the CounterResetHint accordingly. (The default value is fine for the normal counter histograms.) Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

beorn7	b5d4a94e9d	textparse: Add gauge histogram support to protobuf parsing With this commit, the parser stops to see a gauge histogram (whether native or conventional) as an unexpected metric type. It ingests it normally, it even sets the `GaugeHistogram` type in the metadata (as it has already done for a conventional gauge histogram scraped using OpenMetrics), but it otherwise treats it as a normal counter-like histogram. Once #11783 is merged, though, it should be very easy to utilize the type information. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
beorn7	e9d9bb1b08	textparse: Handle unknown metric types in protobuf gracefully So far, the parser hasn't validated that the type is valid in the `Next()` call. Later, in the `Series()` call, however, it assumes that we will only see valid types and therefore panics with `encountered unexpected metric type, this is a bug`. This commit fixes said bug by adding validation to the `Next()` call. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
Damien Grisonnet	96b9d8cebb	model/textparse: associate correct token to errors In some cases, the Prometheus HTTP format parser was not returning the right token in the error output which made debugging impossible. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com>	2 years ago

Bryan Boreham	8120af22e2	benchmarks: SetBytes takes bytes per operation Where the code was multiplying bytes by number of operations, this resulted in absurdly high throughput numbers. Also, in `BenchmarkParse()`, don't run the `expfmt` case twice. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
beorn7	a7c519930e	histograms: Add Compact method to the normal integer Histogram And use the new method to call to compact Histograms during parsing. This happens for both `Histogram` and `FloatHistogram`. In this way, if targets decide to optimize the exposition size by merging spans with empty buckets in between, we still get a normalized results. It will also normalize away any valid but weird representations like empty spans, spans with offset zero, and empty buckets at the start or end of a span. The implementation seemed easy at first as it just turns the `compactBuckets` helper into a generic function (which now got its own file). However, the integer Histograms have delta buckets instead of absolute buckets, which had to be treated specially in the generic `compactBuckets` function. To make sure it works, I have added plenty of explicit tests for `Histogram` in addition to the `FloatHistogram` tests. I have also updated the doc comment for the `Compact` method. Based on the insights now expressed in the doc comment, compacting with a maxEmptyBuckets > 0 is rarely useful. Therefore, this commit also sets the value to 0 in the two cases we were using 3 so far. We might still want to reconsider, so I don't want to remove the maxEmptyBuckets parameter right now.
