Each such record holds:
•
Date and time of the sample
This timestamp is based on the local time in effect at the Adaptive Server
that was monitored
•
Values of all of the data items sampled
If no data is returned for this view during a given sample interval, a placeholder
record is written to the historical data file. This record contains the timestamp
of the sample, followed by a comma-separated list of empty values. That is, the
timestamp field is followed by as many commas as are needed to separate the
remaining data items of the view, but no values are stored for those data items.
This format is acceptable to the Bulk Copy utility, provided that the columns
into which the data items are being copied will accept nulls.
Any error messages that are received while recording samples for a session are
stored in a separate error message file. This file's name is eSessionId where:
•
e is a constant.
•
SessionId is the unique identifier for the session.
Each record in this file contains the following fields:
•

Historical Server from retrieving the sample timestamp.
•
