Björn Rabenstein	dbab4957f7	Merge pull request #9027 from prometheus/beorn7/histogram2 Hacky implementation of protobuf parsing	5 years ago
beorn7	5de2df752f	Hacky implementation of protobuf parsing This "brings back" protobuf parsing, with the only goal to play with the new sparse histograms. The Prom-2.x style parser is highly adapted to the structure of the Prometheus text format (and later OpenMetrics). Some jumping through hoops is required to feed protobuf into it. This is not meant to be a model for the final implementation. It should just enable sparse histogram ingestion at a reasonable efficiency. Following known shortcomings and flaws: - No tests yet. - Summaries and legacy histograms, i.e. without sparse buckets, are ignored. - Staleness doesn't work (but this could be fixed in the appender, to be discussed). - No tricks have been tried that would be similar to the tricks the text parsers do (like direct pointers into the HTTP response body). That makes things weird here. Tricky optimizations only make sense once the final format is specified, which will almost certainly not be the old protobuf format. (Interestingly, I expect this implementation to be in fact much more efficient than the original protobuf ingestion in Prom-1.x.) - This is using a proto3 version of metrics.proto (mostly to be consistent with the other protobuf uses). However, proto3 sees no difference between an unset field. We depend on that to distinguish between an unset timestamp and the timestamp 0 (1970-01-01, 00:00:00 UTC). In this experimental code, we just assume that timestamp is never specified and therefore a timestamp of 0 always is interpreted as "not set". Signed-off-by: beorn7 <beorn@grafana.com>	5 years ago

Dieter Plaetinck	58917d1b76	sparsehistogram: integer types and timestamp separation (#9014 ) * integer types and timestamp separation 1) unify types to int64. as suggested by beorn. we want to support counters going down (resets) even if we plan to create new chunks for now, in that case 2) histogram type doesn't know its own timestamp. include it separately in appending and iteration Signed-off-by: Dieter Plaetinck <dieter@grafana.com> * correction: count and zeroCount to remain unsigned to make api more resilient and that's what we use in protobuf anyway Signed-off-by: Dieter Plaetinck <dieter@grafana.com> * temp hack. Ganesh will fix Signed-off-by: Dieter Plaetinck <dieter@grafana.com>	5 years ago

Björn Rabenstein	df3b674f01	Add metrics.proto to other protobuf code (#8996 ) We cannot just use prometheus/client_model directly because we want to stay consistent with the use of gogo-protobuf. So this converts metrics.proto to proto3 and edits it lightly so that it fits into the framework how prometheus/prometheus handles protobuf. Note that metrics.proto couldn't be merged into the prompb package because prompb already has an Exemplar type, which is different from the Exemplar type in metrics.proto. The directory structure seems to play a role in the protobuf world, so I better kept it. Signed-off-by: beorn7 <beorn@grafana.com>	5 years ago
