Even before you automate your network performance monitoring and management, you’ll need to do some planning. If you don’t have experts on hand, consider bringing in a reliable, dependable network advisor to help you :
Establish a performance baseline
Planning involves establishing baseline performance thresholds — called quality-of-service (QoS) rules — using historical data, estimates of how existing services will grow, and anticipated demand for new services.To determine if your plan is working, you’ll need to measure current network behavior. Such metrics include the traffic generated at certain interface points and the load levels of trunks and devices.
This is how network administrators monitor and manage network conditions. When conditions are out of whack, an alert is generated.
These alerts can indicate an emerging issue, such as a need for additional resources, or a serious problem, such as load levels so high that network and/or application performance has been impacted.
