CounterData

The CounterData table contains a row for each counter that is collected at a particular time. There will be a large number of these rows.

The CounterData table defines the following fields:

• GUID: GUID for this data set. Use this key to join with the DisplayToID table.
• CounterID: Identifies the counter. Use this key to join with the CounterDetails table.
• RecordIndex: The sample index for a specific counter identifier and collection GUID. The value increases for each successive sample in this log file.
• CounterDateTime: The time the collection was started, in UTC time.
• CounterValue: The formatted value of the counter. This value may be zero for the first record if the counter requires two sample to compute a displayable value.
• FirstValueA: Combine this 32-bit value with the value of FirstValueB to create the FirstValue member of PDH_RAW_COUNTER. FirstValueA contains the low order bits.
• FirstValueB: Combine this 32-bit value with the value of FirstValueA to create the FirstValue member of PDH_RAW_COUNTER. FirstValueB contains the high order bits.
• SecondValueA: Combine this 32-bit value with the value of SecondValueB to create the SecondValue member of PDH_RAW_COUNTER. SecondValueA contains the low order bits.
• SecondValueB: Combine this 32-bit value with the value of SecondValueA to create the SecondValue member of PDH_RAW_COUNTER. SecondValueB contains the high order bits.

The GUID, CounterID, and RecordIndex fields make up the primary key for this table.
