Overview of performance monitoring in Fabric Manager

The performance monitoring feature in Fabric Manager provides insight into how much traffic a

particular port or device is generating on the fabric over a specific timeframe. It is also used to

indicate the devices that are creating the most traffic and to identify the ports that are the most

congested.

You configure alerts at both the SAN and fabric level.

Performance monitoring is enabled or disabled on an entire fabric, not on a switch or port basis.

Before you can enable performance monitoring and create reports, graphs, or report templates,

you must first log in to the seed switch of the fabric. The seed switch must have an activated

Advanced Performance Monitoring license to use the end-to-end feature (it is not required for port

statistics monitoring). End-to-end monitors are not set on switches without the license.

The benefit of using performance monitoring is diminished if it is enabled or disabled on an

as-needed basis. Performance monitoring should be enabled constantly to receive the necessary

historical data required for a meaningful report.

You can use Fabric Manager or an external tool (such as Crystal Reports) to run reports and

generate graphs based on the information captured in Fabric Manager.

All the data collected in performance monitoring is stored in the database. If you are monitoring

large fabrics, ensure that you have ample database space to store all of the information.

If you delete a fabric, all performance monitoring data for that fabric is also deleted from the

database.

SNMP v3 is supported for switches running Fabric OS version 4.x or later; if you configure a switch

that is running a version of Fabric OS earlier than 4.x, or a switch that is running XPath, configuring

Performance Monitoring for SNMP v3 will result in no data collection.

NOTE

Fabric Manager does not support Advanced Performance Monitoring on GigE ports and Access

Gateway-moded switches.
