ERROR NetVizAgentRequest - Fatal transport error while connecting to URL

How do I turn off the attempted communication from the JavaAgent to the Network Visibility agent?

 

The JavaAgent running in a docker image emits this error message periodically to its log:

 

[AD Thread Pool-Global9] 12:57:01,474 ERROR NetVizAgentRequest - Fatal transport error while connecting to URL [http://127.0.0.1:3892/api/agentinfo?timestamp=0&agentType=APP_AGENT&agentVersion=0.3.0]: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:3892 [/127.0.0.1] failed: Connection refused (Connection refused)

 

I gather we do not have a license for the NVA - so do not need this.

 

Also, is there any reason to have all the logging levels in the Java agent set to INFO? A huge amount of noise is generated that does not seem to have much value - might it be better to choose ERROR?

Hi, you will need to check if you have licensing for Netviz and configure it if needed.

 

To remove the noise you can do either or both

 

1. Set a node property as follows for the Java nodes(If you want to keep the netviz folder, or can't remove it)

socket-enabled = False(use boolean values)

 

This will disable/ignore netviz

 

2. Complete remove the netviz folder from the agent directory below

ver20.x.x\external-services\

 

Ciao
