This section provides information, how to handel the Java Exception when VCO discovery fails.

If the VCO discovery fails with Java Exception and below message appears in discovery collector logs:
WARNING – [2019-06-12 13:44:07 IST] – HttpRequestGroup::executeRequest(): Error running command 
@{protocol}://@{host}:@{PORT}/portal/rest/enterprise/getEnterpriseEdges on host for requests group 
RETRIEVE ENT EDGES TO FORM TUNNEL org.apache.http.conn.ConnectTimeoutException: 
Connect to [/] failed: Read timed out

Then, need to increase the timeout "connection-timeout="120s" in "<DCF-InstallLocation>/Collecting/Stream-Collector/<Collector-Instance>/conf/requests/discovery-retriever.xml".

Timeout can be increased based on the actual time taken to get an API response from VCO.
