the same set of counters for which the
live data is shown. You can view
charts for the respective counters in
the Charts section.

the Historical Statistical Data section.
Live Data
This section displays the live bar-chart, where you can view live data samples for a controller or
host port. In addition, you can view live data for the storage system too, which is the same live
data that is already being shown under the Dashboard
→Overview tab. The data samples displayed
for a host port indicates the current read and write I/O requests, and average latencies observed
with that specific host port. The data appears for a set of dashboard counters that are health
indicators for the selected storage system, controller, or host port. For a brief description of each
dashboard counter, see
“Dashboard counters” (page 98) .
By default, this section displays data for a storage system. To view live data for a controller or host
port, choose that performance object in the Select a performance object list. The Live Data and the
Historical Statistical Data sections are refreshed for the selected performance object. For more
information on statistical data shown, see
“Historical Statistical Data” (page 100) .
The threshold levels displayed for the following are based on:
•
Storage System: The configured threshold values for the dashboard counters under the
Dashboard Settings tab are considered (see
“Configuring dashboard settings” (page 62) ).
•
Controller: The same threshold values configured for the dashboard latency counters (Average
Read Latency(ms), Average Write Latency(ms)) for the storage system are considered. However,
for the I/O counters (Total Read Req/s, Total Write Req/s), the threshold values are considered
as half of the corresponding threshold values configured for the dashboard I/O counters.
•
Host Port: If a threshold profile is configured and associated with the host port, the
corresponding threshold values are considered.
The interpretation of live data for a controller or host port is similar to that of a storage system. For
more information, see
“Storage System – Live Host Port Throughput and Latency Values” (page 91) .
