Changed Monitoring Tables

Adaptive Server 15.7 SP100 includes changes to existing monitoring tables.

monOpenObjectActivity

monOpenObjectActivity adds these colums:
Description Datatype Description
NumLevel0Waiters float Number of times a Level0 Scan start waited because of a utility's wait request.
AvgLevel0WaitTime float Average time, in milliseconds, Adaptive Server waited for Level0 access.

monRepLogActivity

The MaxHashSchemaSize and NumberOfSchemasReused columns of the monRepLogActivity table have been removed.

monRepScanners

The NumberOfTruncPointRequested and NumberOfTruncPointMoved columns are populated only when the single task scanning of a log model is used. When the Multiple Replication Paths (MRP) model is used, these columns values are 0. The monRepSenders table contains related information for the MRP model.

monRepSenders

Description Datatype Description
NumberOfTruncPointRequested int Total number of times RepAgent asked Replication Server for a new truncation point.
NumberOfTruncPointMoved int Total number of times RepAgent moved the secondary truncation point.
AvgTruncPointInterval int Displays the average time between truncation point requests. This value is an indication of the effectiveness of the trunc point request interval configuration parameter. If trunc point request interval is set correctly, the values of trunc point request interval and AvgTruncPointInterval will be the same.

monSpinlockActivity

Name Datatype Attribute Description
SpinlockSlotID int   ID for this spinlock in the spinlock memory pool

monState

Enable the enable monitoring configuration parameter for this monitoring table to collect data.
