+++ This bug was initially created as a clone of Bug #1757547 +++ Description of problem: The following error sometimes occurs when metering is importing CPU or memory usage metrics in the pod-usage-cpu-cores or pod-usage-memory-bytes ReportDataSources. time="2019-10-01T19:16:51Z" level=error msg="error collecting metrics" app=metering chunkSize=5m0s component=PrometheusImporter endTime="2019-10-01 19:16:39.238555324 +0000 UTC" error="failed to perform Prometheus query: execution: many-to-many matching not allowed: matching labels must be unique on one side" logID=OBju7Ykcm2 namespace=metering-chancez2 reportDataSource=pod-usage-cpu-cores startTime="2019-09-23 23:12:00 +0000 UTC" stepSize=1m0s tableName=hive.metering.datasource_metering_chancez2_pod_usage_cpu_cores Version-Release number of selected component (if applicable): 4.3.0 How reproducible: This seems to depend heavily on the metrics in Prometheus. I cannot determine what part of the query causes it yet, but it's caused by a group_left from the container usage metrics to the kube_pod_info metrics. Steps to Reproduce: Unknown Actual results: Failed to perform Prometheus query, thus no metrics imported Expected results: Promtheus queries in ReportDataSources do not error when doing group_left, and metrics are imported. Additional info:
The above description should say the effected version is 4.2.0, i forgot to modify that when cloning.
Move it back to POST due the bug dropped from errata. Please move it back to ON_QA once https://github.com/operator-framework/operator-metering/pull/1016 is merged. Thanks!
PR #1016 was merged, so moving back to ON_QA.
