Hi,
To sum up it allow you to implement a Dynamic Ratio load balancing depending of your systemp performance.
real_server monitor provides a monitor plug-in that gathers the necessary metrics when you have installed the plug-in on the RealSystem Server system (windows or linux). Configuring a RealSystem
Server for Dynamic Ratio load balancing consists of four tasks:
- Installing the monitor plug-in on the RealSystem Server system
- Configuring a Real Server monitor on the BIG-IP system
- Associating the monitor with the server to gather the metrics
- Creating or modifying the server pool to use Dynamic Ratio load balancing
Once the plug-in is installed and compiled, you must configure a Real Server monitor, associate the configured monitor with the node (a RealSystem Server server), and set the load balancing method to Dynamic Ratio.
