7 Monitoring Equalizer Operation
System status information and performance statistics can be gathered and displayed from within the
Equalizer Administrative Interface; higher-end Equalizers can also be monitored using standard
Simple Network Management Protocol (SNMP) utilities:
• To display the current Equalizer status (a summary of global parameters and usage
statistics), see “Displaying Equalizer Status” on page 100.
• To display messages recorded in the operating system, cluster, and server logs, see
“Displaying the System Event Log” on page 101.
• To display a status report on all virtual clusters, see “Displaying the Virtual Cluster
Summary” on page 103
• To examine the current configuration of a cluster and plot a graph showing its usage over
time, see “Displaying Cluster Information” on page 104 and “Plotting Cluster Performance
History” on page 105.
• To examine the current configuration of a server and plot a graph showing its usage over
time, see“Displaying Server Information” on page 107 and “Plotting Server Performance
History” on page 108.
• To examine the current configuration of a geographic cluster and plot a graph showing its
usage over time, see “Displaying Geographic Cluster Parameters” on page 110 and “Plotting
Geographic Cluster Performance History” on page 111.
• To examine the current configuration of a site within a geographic cluster and plot a
graph showing its usage over time, see “Displaying Site Information” on page 112 and
“Plotting Site Performance History” on page 113.
• To configure logs used to collect plotting data, see “Configuring Plot Logs” on page 113.
• To export usage statistics to a comma separated value (csv) file, see “Exporting Usage
Statistics” on page 114.
• To configure log forwarding, email notification of events, or execution of an external
command on events, see “Configuring Custom Event Handling” on page 114.
• To configure the SNMP agent on an Equalizer Model E450si (or above), see “Browsing
Equalizer Configurations using SNMP” on page 117.
