Storage System – Live Host Port Throughput and Latency Values
This section of Dashboard Overview tab contains the live bar-chart that indicates the current overall
performance of the storage system. The data is constantly refreshed at five-second intervals and
appears for the following storage-system-specific dashboard counters that are the health indicators
for your storage system:
•
Total Read Req/s
•
Average Read Latency (ms)
•
Total Write Req/s
•
Average Write Latency (ms)
For a description of dashboard counters, see
“Dashboard counters” (page 98)
.
Each live data sample displayed for a dashboard counter constitutes the current throughput or
latency of all the host ports from both the controllers associated with the storage system. The value
signifies the current aggregate or average performance of all host ports across controllers in the
storage system.
For the live data samples to appear for a storage system, you must configure the minor and major
threshold levels for the following counters in the Summary Data window, under the Dashboard
Settings tab:
•
Read Req/s
•
Read Latency (ms)
•
Write Req/s
•
Write Latency (ms)
