  Returns:

  - the SQL that was executed or the string "batch" if it was a batch execution

• getThreshold

  public long getThreshold()

  Returns:

  the threshhold in milliseconds

• setThreshold

  public void setThreshold(long threshold)

  Sets the query measurement threshold. The value is in milliseconds. If the query goes faster than this threshold it will not be recorded.
