8 Using the Performance Monitor
The performance monitoring feature in Fabric Manager provides insight as to how much traffic a particular
port or device is generating on the fabric over a specific timeframe. It also indicates the devices that are
creating the most traffic and identifies the ports that are the most congested.
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 launch switch of the fabric. The launch switch must have an activated HP StorageWorks
Advanced Performance Monitoring license if you want 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 needs to 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. To monitor 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.

Performance monitoring components
Before you start using performance monitoring on your fabric, you need to be familiar with the following
components:
• Port statistics, next
• End-to-end monitoring, page 88
• Granularity, page 88
• Reports, page 89
• Graphs, page 89
• Templates, page 89
Port statistics
The port statistics component in the performance monitoring feature in Fabric Manager allows you to see
how much traffic a particular port is generating on a fabric over a period of time. The receive (RX) and
transmit (TX) values for ports are retrieved over a specific timeframe and stored in a database. Monitoring
port statistics does not require an Advanced Performance Monitoring license.
