Documentation forNetwork Performance Monitor
Monitoring network performance is a key capability of SolarWinds Observability Self-Hosted (formerly Hybrid Cloud Observability) and is available in the Essentials edition. Network Performance Monitor (NPM) is also available in a standalone module.

Determine interface status in connections for the SolarWinds Platform

Connections are shown as either solid or dotted lines. A solid line indicates that the connection is UP. A dotted line indicates that the connection is DOWN.

The connection status depends on the status of interfaces at both ends of the connection.

The connection status is only shown as either UP or DOWN. To emphasize potential problems, DOWN status is granted a higher priority.

The following table shows how interface states are reflected in the status of a connection between NodeA, with InterfaceA, and NodeB, with InterfaceB.
