Can you check the TOP command?
The top command is generally used to check memory and cpu usage per process. However it also reports total memory usage and can be used to monitor the total RAM usage. The header on output has the required information.
Hello @Sreedhar M.,
You can use the Agent Breakdown to know the time spent in the target application of the Agent which provides a view of accumulated performance data and secondly you can plot a chart for the Bytes Read from Agent measure from the dynaTrace Self-Monitoring which because this is often an indicator of the overhead caused by the agent.
