Windows Azure Diagnostics Column Explanations

The default columns recorded by Windows Azure Diagnostics are:

  • PartitionKey - ?????
  • RowKey - ?????
  • Timestamp - The time and date this log was recorded
  • EventTickCount - ?????
  • DeploymentId - ?????
  • Role - The name of the Worker/Web Role this log call was made from
  • RoleInstance - The name of the Azure Application Instance this log call was made from
  • Level - The level (Debug, Info, Error) of this log
  • EventId - ?????
  • Pid - ?????
  • Tid - ?????
  • Message - The actual contents of the log call

I've scoured MSDN for an explanation of what information is recorded in each of these columns. I can infer the meaning of some of them based on the name of the column and the data it contains, but there are some I can't figure out.

What data is recorded in PartitionKey, RowKey, EventTickCount, DeploymentId, EventId, Pid, and Tid?

In order:

PartitionKey / RowKey - Every entity in table storage requires three properties: PartitionKey, RowKey, Timestamp. The PartitionKey is used in partitioning tables across storage nodes. The RowKey is a unique identifier within a given partition. At the time of this writing, Windows Azure Diagnotics appears to be using the timestamp to generate these values. References: 1 2

EventTickCount - The timestamp of when the event was generated in ticks.

DeploymentId - the guid assigned to this particular deployment. Used to differentiate one deployment from another.

EventId - the id of the event that was traced. See details about ETW for more information.

Pid - the process id of the process which generated the event.

Tid - the thread id of the thread which generated the event.
