show stats storage dr-latency
When using replication, this command displays the average latency (in milliseconds) of write operations to the secondary data center for the specified LUN. This includes the latency of the inter-data center network and the latency of the backend being used on the secondary.
Syntax
show stats [failover-peer] storage dr-latency {interval <time-interval> lun <lun-id> | start-time <start> end-time <end> lun <lun-id>}
Parameters
failover-peer | Performs the command on the failover peer of the current appliance. |
interval <time-interval> | Returns statistics for one of the following time intervals: • 1min—Past minute. • 5min—Past five minutes. • hour—Past hour. • day—Past day. • week—Past week. • month—Past month. |
lun <lun-id> | Specifies the identifier of the desired LUN. |
start-time <start> | Specifies the start time to return statistics. Use the format 'yyyy/mm/dd hh:mm:ss'. |
end-time <end> | Specifies the end time to return statistics. Use the format 'yyyy/mm/dd hh:mm:ss'. |
Usage
All failover-peer commands enable you to perform the command on the failover peer of the current appliance.
