Logreader records accepted

Logreader records accepted/sec in the Source database

Logreader records filtered

Logreader spm add

Logreader space manager add space

Logreader spm get

Logreader space manager get space

Logreader spm extra add

Logreader space manager add extra space

Logreader spm reqcount

Logreader log space request per second.

Logreader spm waitct

Logreader log space waits per second.

When the Logreader buffer is full, write operations get throttled and must wait. Each time a wait occurs, this counter is incremented. The higher the counter value, the more negative the write throttling effect is.

See the suggestions for the Logreader spm freespc min counter.

Logreader spm freespc min

Minimum value of Logreader space manager free space (number of operations that can be buffered).

Each Logreader cursor has its own free space counter; if there are multiple open Logreader cursors, the value is the minimum value of free space of all open cursors. If the free space of any Logreader cursor is zero, the value of this counter is zero and transaction throttling (slowdown) is enacted.

This counter, in conjunction with the Logreader spm waitct counter, is important in determining whether write throttling is happening inside the solidDB server. Write throttling occurs when no space is available in the Logreader buffer because of data not replicating to the back-end database quickly enough. Depending on your workload, occasional occurrences of this can be acceptable if not many write operations are having to wait; see the Logreader spm waitct counter. If this value is consistently 0, consider increasing the Logreader.Maxspace configuration parameter.

Logreader spm freespc max

Maximum value of Logreader space manager free space (number of operations that can be buffered). If there are multiple open Logreader cursors, the value is the maximum value of free space of all open cursors.
