ID: 15151 Title: azure_storageaccounts: Fix aggregation type and units in performance check Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 There were several bugs in the Azure Storage performance check plugin. Success server latency and End-to-end server latency had no units in the service summary and showed wrong units in the metrics. The aggregation of all three metrics was wrong, total instead of avergage, which led to incorrect values being shown.
