Network Node Dashboard view
The Network Node Dashboard view is a network device specific dashboard view. You can access this view by selecting the network device you wish to view information for, and then in the Tasks pane, clicking Network Node Dashboard. This view allows you to view the following information about a specific device:
- Vicinity view of the node
- Availability statistics of the node over the last 24 hours / 48 hours / 7 days / 30 days
- Node properties
- Average response time
- Processor usage over the last 24 hours
- Current node interface health
- Alerts generated by the node
- Alert details
Network Interface Dashboard view
Operations Manager monitors network interfaces, such as the ports on monitored switches, as long as they are connected to other devices that Operations Manager also monitors. For example, a port on a monitored switch will be monitored if it also connects to a computer that is monitored by Operations Manager. The Network Interface Dashboard view allows you to view information about a specific interface on a monitored network device. This dashboard is accessible through the Network Node Dashboard view by clicking on Network Interface Dashboard in the Health Of Interfaces on this node area. The Network Interface Dashboard view provides the following information:
- Bytes sent and received over the past 24 hours
- Packets sent and received over the past 24 hours
- Interface properties
- Send and receive errors and discards over the past 24 hours
- Network interface usage percentage
- Alerts generated by this interface
- Alert details
The Network Vicinity Dashboard allows you to view a diagram of a device and all of the monitored devices and computers that connect directly to that device. You can configure the Network Vicinity Dashboard to go beyond direct connection, expanding out to five levels of connection. The Network Vicinity Dashboard provides a graphical representation of each monitored object and the health of the connections between those objects.
