Example: comparing different metric traces on the same device or interface

Use the custom dashboard that contains the two Top Performers widgets to compare different metric traces on the same device or interface; for example, you might see a number of incidences of high snmpInBandwidth on a specific interface over the last day. To determine if the high incoming SNMP bandwidth usage on this interface is affecting the outgoing SNMP bandwidth usage on that same interface, you can, on the same dashboard, also display a trace for the snmpOutBandwidth metric on the same interface and also over the last day, and then visually compare the two traces.

1. In the Network Views widget, select a network view.
2. From each of the Top Performers widgets, click the Metric drop-down list and select a metric of interest; for example snmpInBandwidth. Select the same metric on both Top Performers widgets; this ensures that the top entity in both chart is always the same.
3. In one of the Top Performers widgets, click the top bar to show the trace for the entity with the top value in that chart.
   This displays a time-based trace of current raw data for the snmpInBandwidth metric.
4. In the other Top Performers widget, click the top bar to show the trace for the entity with the top value in that chart.
   You are now showing the identical time trace in both widgets.
5. In the second Top Performers widget, click the Metric drop-down list and select snmpOutBandwidth.
   You are now displaying a trace of incoming SNMP bandwidth usage on the interface with the highest incoming SNMP bandwidth usage in the network view on one widget, and a trace of outgoing SNMP bandwidth usage on that same interface. You can now visually compare the two traces to see if there is any correlation.
