Event visualization tasks
Operators can view events lists and use event severity ratings to quickly identify high-priority device events.
Operators can switch from alert views to topology views to see which devices are affected by specific alerts. They can also identify root cause alerts and list the symptom alerts that contribute to the root cause. Alerts may be generated by the Network Manager polling mechanism, or may be received from other network management systems.
Network operators use event visualization tools to perform the
following tasks:
- Viewing event lists and using event severity ratings to quickly identify high priority device alerts.
- Switching from event lists to topology views (Network Hop Views and network views) to see which devices are affected by specific events, and to explore the network in context for related issues
- Identifying root cause events and listing symptom alerts that contribute to the root cause.
- Identifying service-affected events, which are indicators that a critical customer service, such as a VPN, has a fault, and listing device events that contributed to a service-affected event
