getWalWritingRate

@MXBeanDescription(value="Average number of bytes per second written during the last time interval.")
float getWalWritingRate()

Deprecated.

Gets the average number of bytes per second written during the last time interval. The length of time interval is configured via PersistentStoreConfiguration.setRateTimeInterval(long) configurartion property. The number of subintervals is configured via PersistentStoreConfiguration.setSubIntervals(int) configuration property.

Specified by:

getWalWritingRate in interface PersistenceMetrics

getWalFsyncTimeAverage

@MXBeanDescription(value="Average WAL fsync duration in microseconds over the last time interval.")
float getWalFsyncTimeAverage()

Deprecated.

Gets the average WAL fsync duration in microseconds over the last time interval.

The length of time interval is configured via PersistentStoreConfiguration.setRateTimeInterval(long) configurartion property. The number of subintervals is configured via PersistentStoreConfiguration.setSubIntervals(int) configuration property.
