For better understanding of connectivity issues related to HTTP Client Logging, you can perform the following steps:

1. Locate the startup.properties file under the GC instance directory:

   user_projects/domains/EMGC_DOMAIN/servers/EMGC_OMS1/data/nodemanager/startup.properties

2. Append the following string to the value of the property Arguments:

   -DHTTPClient.log.level\=ALL -DHTTPClient.log.verbose\=true

3. Restart the OMS, and the WebLogic Server Administration Manager by running the following commands:

   emctl stop oms -all

   emctl start oms

4. Navigate to the following location to check the log file:

   user_projects/domains/EMGC_DOMAIN/servers/EMGC_OMS1/logs/EMGC_OMS1-diagnostic.log

   Alternately, you can also use the grep command to find all the HTTP connection logs as follows:

   grep HTTPClient EMGC_OMS1-diagnostic*.log
