Metric Descriptions

Average Redo Write Time

The average time (ms) spent writing a redo log entry to the log files. User sessions experience log write waits when, upon commits, an individual session waits for the LGWR to flush its redo information to the redo log file.

Balance Archive Waits

The extent to which archive wait events are balanced across RAC nodes.

Balance Average Redo Write Time

The extent to which average redo write time is balanced across RAC nodes.

Balance Redo Waits

The extent to which average redo wait events are balanced across RAC nodes.

Balance Redo Writes

The extent to which redo writes are balanced across RAC nodes.

Number of transactions committed during the current interval. After a transaction is committed, the redo generated by that transaction reflects the changes made to database blocks, which must be written to disk.

Log File Sync Event

Average time spent on writing redo log entries during a commit.

Log Switch Wait

The time the session spent waiting for the completion of a redo log switch.

Time spent waiting for the completion of a write (physical I/O) to a logfile. LGWR experience log write waits when it periodically flushes the contents of the log buffer into the active log file.

Elapsed redo wait time, including the time spent waiting on contention resulting from:

•

User sessions writing redo entries to the redo log buffer

•

LGWR writing the log buffer contents into the active redo log file

•

ARCH archiving redo logs to the destination location

Total number of write operations issued by the log writer (LGWR) to the redo log files.

Redo Writes Volume

Total amount (in megabytes) of redo operations generated and written to redo logs

Time to Sync a Redo Log Entry

Average time spent on writing single redo log entry to logfile during a commit.
