Chapter 58 Performance Monitoring
Historical Performance Monitoring
Historical Performance Monitoring
Performance Manager gathers network device statistics historically and provides this information
graphically using a web browser. It presents recent statistics in detail and older statistics in summary.
Performance Manager also integrates with external tools such as Cisco Traffic Analyzer.
See the “Performance Manager Architecture” section on page 8-1 for an overview of Performance
Manager.
Creating a Flow with Performance Manager
Performance Manager has a Flow Configuration Wizard that steps you through the process of creating
host-to-storage, storage-to-host, or bidirectional flows. See the
“Flow Statistics Configuration” section
on page 8-6 for information on creating flows.
Creating a Collection with Performance Manager
The Performance Manager Configuration Wizard steps you through the process of creating collections
using configuration files. Collections are defined for one or all VSANs in the fabric. Collections can
include statistics from the SAN element types described in
Table 58-1.
Using Performance Thresholds
The Performance Manager Configuration Wizard allows you to set up two thresholds that trigger events
when the monitored traffic exceeds the percent utilization configured. These event triggers can be set as
either Critical or Warning events that are reported on the Fabric Manager web client Events browser
page.
You must choose either absolute value thresholds or baseline thresholds that apply to all transmit or
receive traffic defined in the collection. Click the Use absolute values radio button on the last screen of
the Performance Manager Configuration Wizard to configure thresholds that apply directly to the
statistics gathered. These statistics, as a percent of the total link capacity, are compared to the percent
utilization configured for the threshold type. If the statistics exceed either configured threshold, an event
is shown on the Fabric Manager web client Events tab.
As an example, the collection has absolute value thresholds set for 60% utilization (for warning) and
80% utilization (for critical). If Performance Manager detects that the traffic on a 1-Gigabit link in its
collection exceeds 600 Mbps, a warning event is triggered. If the traffic exceeds 800 Mbps, a critical
event is triggered.
