BI performance counter: BLOB files in use

Applies to



This performance counter monitors the total number of binary large object (BLOB) files in use for spooling by the data flow engine within a given time period. The value of this performance counter fluctuates as BLOB files are used and disposed. The value of this counter is usually high and could be reset back to zero whenever the SSIS service is restarted.
