The operational problem
A reachable device can still have an overloaded or failing interface. Network investigation needs both availability and the counters the device actually exposes.
What you can monitor
Use ICMP reachability and supported SNMP device/interface observations. Device sensors and normalized labels depend on its approved profile.
A practical workflow
- Choose a Site Edge that can reach the management network.
- Configure a read-only SNMP identity and review the required device profile.
- Validate collection and inspect discovered interfaces.
- Follow a warning to the affected asset, incident and topology context.
Reports for the decision
Network reports combine the selected scope and period with available observations and explicit gaps.
