Remote debugging of Java applications from an IDE can be essential when debugging difficult issues. There is no reason to give this functionality up just because you are deploying to a container in Cloud Foundry.
In this article we’ll go over how to enable remote debugging from a local Eclipse IDE to a public CF provider like Pivotal CloudFoundry.

Nginx is a powerful application level proxy server. Whether for troubleshooting or analysis, enabling log levels and custom formats for the access/error logs is a common requirement.
By default, only messages in the error category are logged. If you want to enable more details, then modify nginx.conf like:

Enabling verbose logs for an AppDynamics machine or database agents can be invaluable for troubleshooting connectivity or network issues.
Luckily, this is easily done by editing the conf/logging/log4j.xml file. By default, only the error level messages are sent to the logs:
But you can modify this so that debug level is sent:
