public class RedisCacheIOMonitor
extends org.apache.jackrabbit.oak.segment.spi.monitor.IOMonitorAdapter

This IOMonitor implementations registers the following monitoring endpoints with the Metrics library if available:

• OAK_SEGMENT_CACHE_REDIS_SEGMENT_READ_BYTES: a meter metrics for the number of bytes read from segment redis cache
• OAK_SEGMENT_CACHE_REDIS_SEGMENT_WRITE_BYTES: a meter metrics for the number of bytes written to segment redis cache
• OAK_SEGMENT_CACHE_REDIS_SEGMENT_READ_TIME: a timer metrics for the time spent reading from segment redis cache
• OAK_SEGMENT_CACHE_REDIS_SEGMENT_WRITE_TIME: a timer metrics for the time spent writing to segment redis cache
