Native histograms without a zero threshold aren't federated properly. This adds a test to prove the specific failure mode, which is that histograms with a zero threshold of zero are federated as classic histograms. The underlying reason is that the protobuf parser identifies a native histogram by detecting a zero bucket or by detecting integer buckets. Therefore, a float histogram with a zero threshold of zero and an unpopulated zero bucket falls through the cracks (no integer buckets, no zero bucket). This commit also addse a test case for the latter. Signed-off-by: beorn7 <beorn@grafana.com> |
