Historical Performance Monitoring Chapter 60 Performance Monitoring Send documentation comments to [email protected] 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 8-3 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 60-1. Table 60-1 Performance Manager Collection Types Collection Type Description ISLs Collects link statistics for ISLs. Host Collects link statistics for SAN hosts. Storage Collects link statistics for a storage elements. Flows Collects flow statistics defined by the Flow Configuration Wizard. 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. 60-4 Cisco MDS 9000 Family Fabric Manager Configuration Guide OL-8007-10, Cisco MDS SAN-OS Release 3.x
