Performance Monitoring

Performance attribute samples and hourly summaries are maintained for all monitored IP resources and nodes. Performance history displays are available from the IP Resource Monitor and the IP Node Monitor, and from some diagnostic displays. These displays can help you identify trends and potential problems in your network.

For example, from the IP Resource Monitor you can look at the performance history for a stack's packet activity as samples and hourly aggregates.

Various styles of graphs are presented, depending on the type of attribute being sampled:

A gauge value (GAUGE), such as average CPU utilization for a router
A rate value (COUNT or TOTAL), which represents change in a counter, for example, errors per hour
Non-numeric values (ENUM) such as status values (for example, OK and TIMEOUT)
