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 1225.
• Configure the graph display using right-click menu options. For more information refer to
“Configuring the graph display” on page 978.
Enabling SAN-wide historical performance collection
To enable historical performance collection, select Monitor > Performance > Historical Data
Collection.
The Fabric Selector dialog box displays with Enable SAN Wide enabled by default. This enables
historical performance data collection for all fabrics in the SAN.
NOTE
After enabling historical data collection, information for switches, ports, and FCIP tunnels also
displays in the IP Historical Graph/Tables dialog box. If available, click the IP tab, then select Monitor
> Performance > Historical Graphs/Tables.
