  • Enum Constant Details

    • START_TIME

      public static final GoogleTaskUsageTraceReader.FieldIndex START_TIME
      0: The index of the field containing the start time​ of the measurement period (stored in microsecond but converted to seconds when read from the file).

    • END_TIME

      public static final GoogleTaskUsageTraceReader.FieldIndex END_TIME
      1: The index of the field containing the end time​ of the measurement period (stored in microsecond but converted to seconds when read from the file).

    • JOB_ID

      public static final GoogleTaskUsageTraceReader.FieldIndex JOB_ID
      2: The index of the field containing the id of the job this task belongs to.

    • TASK_INDEX

      public static final GoogleTaskUsageTraceReader.FieldIndex TASK_INDEX
      3: The index of the field containing the task index within the job.

    • MACHINE_ID

      public static final GoogleTaskUsageTraceReader.FieldIndex MACHINE_ID
      4: The index of the field containing the machineID. If the field is present, indicates the machine onto which the task was scheduled, otherwise, the reader will return -1 as default value.

    • MEAN_CPU_USAGE_RATE

      public static final GoogleTaskUsageTraceReader.FieldIndex MEAN_CPU_USAGE_RATE
      5: The index of the field containing the mean CPU usage rate (in percentage from 0 to 1).

    • CANONICAL_MEMORY_USAGE

      public static final GoogleTaskUsageTraceReader.FieldIndex CANONICAL_MEMORY_USAGE
      6: The index of the field containing the canonical memory usage, i.e., the number of user accessible pages, including page cache but excluding some pages marked as stale.

    • ASSIGNED_MEMORY_USAGE

      public static final GoogleTaskUsageTraceReader.FieldIndex ASSIGNED_MEMORY_USAGE
      7: The index of the field containing the assigned memory usage, i.e., memory usage based on the memory actually assigned (but not necessarily used) to the container where the task was running inside the Google Cluster.

    • UNMAPPED_PAGE_CACHE_MEMORY_USAGE

      public static final GoogleTaskUsageTraceReader.FieldIndex UNMAPPED_PAGE_CACHE_MEMORY_USAGE
      8: The index of the field containing the unmapped page cache memory usage, i.e., Linux page cache (file-backed memory) not mapped into any userspace process.
