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 1855.
• Configure the graph display using right-click menu options. For more information refer to
“Configuring the graph display” on page 1474.
