Regarding the issue of Sflow traffic not being displayed in Applications

[shan Sha]

Problem description: I deployed sflow rt on a virtual machine, and the front-end page opened normally. I used a Python script to simulate sflow agent sending sflow messages to the virtual machine. The agent and sflow traffic can be recognized on the front-end page of the virtual machine, but the corresponding indicators cannot be selected in browse metrics for viewing.

Could you check the output of /analyzer/json REST query? It will tell you if there are parse errors, how many flow samples and counter samples were received etc.

Are you generating counter samples? The Metrics Browser will only show data if you are receiving counter samples (or are receiving flow samples and have defined a flow metric).
