SAN historical performance data
Performance monitoring should be enabled constantly to receive the necessary historical data
required for a meaningful report. The following options and features are available for obtaining
historical performance data:
•
Collect historical performance data from the entire SAN or from a selected fabric.
NOTE
Virtual Fabric logical ISL ports are not included in performance data collection.
•
Persist data on every polling cycle (5 minutes).
•
Store records for each port.
•
Use the Round Robin Database (RRD) style aging scheme.
•
Enable a granularity for data collection:
-
5 minute granularity for last 8 days
-
30 minutes granularity for last 14 days
-
2 hour granularity for last 30 days
-
1 day granularity for last 730 days
•
Plot advanced monitoring service (AMS) violation events received during the chart time range
and Master Log events logged on the same product as the measure being plotted.
•
Generate reports. For instructions on generating reports, refer to “Generating SAN
performance reports” on page 1405.
