Nimble Storage: Read Latency
This check monitors the latency of read IO operations. The total reads will
always be displayed. Additionally read IO latency groups will be displayed
if the counter is greater than a given threshold. The state will change
accordingly to the defined threshold.
Thresholds and correlating states can be defined for each latency group.
One services for each volume will be created.
