How much load does Performance Analysis put on the Network Bandwidth? What is the average size of the packet that is sent between Performance Analysis Agents (Middleware and Collector)?
Most of the network traffic between the Collector and the Middleware are messages that the Collector sends every 5 seconds to the Middleware. This message contains data that:
This message's size is not constant, but depends on the number of statements and sessions within the monitored instance.
The message constant size is 310 bytes. In addition, the message contains the following data:
During a one hour period (which is 720 times 5 seconds), 250 MB of data items are sent.
In such a case, the average size per message would be smaller than 1,500 bytes.
The calculation of sending 250MB per hour is based on running 3 sessions and 3 statements.
