NSX Traceflow Utility

Understanding NSX's Traceflow Utility

What Traceflow is for:

Traceflow is useful in the following scenarios: 

■	Troubleshooting network failures to see the exact path that traffic takes
■	Performance monitoring to see link utilization
■	Network planning to see how a network will behave when it is in production

Prerequisites

■	Traceflow operations require communication among vCenter, NSX Manager, the NSX Controller cluster and the netcpa user world agents on the hosts.
■	For Traceflow to work as expected, make sure that the controller cluster is connected and in healthy state.

Step 1: 
Log into the Web Client and Select the NSX Plugin

Step 2: 
Select Traceflow on the left.

Step 3:

Step 4:

Step 5: 
Now select the destination.

Step 6:  
In this case, select Layer 3.

Step 7: 
Add the IP address of the source vm.

Step 8:  
Verify your selections and click on Trace.

Step 9: 
Wait a few seconds...

Step 10: 
In this case, notice the firewall dropped such traffic. The firewall demo is found on the previous post. 

Step 11:  
Same trace without the firewall rule preventing that type of traffic.
