The Port Health screen in the Admin workspace enables you to view statistics related
to the SMS server ethernet ports. To open the screen, expand the General node in the
navigation pane and select
Port Health.
The Port Health screen displays a summary of port usage statistics in a table, and
shows longer-term historical statistics in a series of graphs. When the SMS is configured
in a HA cluster, the Port Health screen displays information for both the active and
the passive server using a separate tabbed view for each server.
The top portion of the Port Statistics screen displays current port statistics in
a table view. For each interface, the table displays the number of bytes incoming
and outgoing, the number of packets discarded, and the number of errors, as described
in the following table.
| Information | Description |
| Interface | Network interface, typically shown as primary port or secondary port. |
| Total In: Bytes | Total number of bytes that have passed into the port. |
| Total Out: Bytes | Total number of bytes that have passed out of the port. |
| Total In: Discards | Number of inbound packets discarded, although no errors were detected. |
| Total Out: Discards | Number of outbound packets discarded, although no errors were detected. |
| Total In: Errors | Sum of all errors that prevented the final transmission of inbound packets. |
| Total Out: Errors | Sum of all errors that prevented the final transmission of outbound packets. |
The Refresh button directly below the table refreshes the current statistics. The
bottom portion of the screen displays a graph for each ethernet port. Data in the
graph shows historical statistics over time.
