linux - Azure Rowkey 和 PartitionKey

Question

我正在使用 Linux 诊断监视附加到 Azure VM 的 VHD。使用 CLI 启用诊断时，监控数据最终位于 PublicConfig.json 中指定的表 (LinuxDiskMetric) 中

azure vm extension set vmturbo volumevm LinuxDiagnostic Microsoft.Azure.Diagnostics '3.0' --private-config-path PrivateConfig.json --public-config-path PublicConfig.json -v

PublicConfig.json 的一部分

......
"perfCfg": [
    {
      "query": "SELECT Name, AverageReadTime, AverageWriteTime, ReadBytesPerSecond, WriteBytesPerSecond FROM SCX_DiskDriveStatisticalInformation",
      "table": "LinuxDiskMetric",
      "frequency": 60
    }
  ]
.....

下面是包含数据的表的屏幕截图。我想根据 Rowkey 和 PartitionKey 查询这些数据，但完全不知道它们是如何生成的以及这些列的含义。有谁知道 Microsoft Azure 如何生成这些？

Answer 1

PartitionKey 和 RowKey 与您的事件日志无关。

PartitionKey value represents the Date/Time value when the event was logged. It actually has the precision of a minute i.e. all the logs data collected in one minute will share same PartitionKey.

RowKey was just an arbitrary index value to ensure all entries in the partition have a unique key.
