1.3.6.1.4.1.9.9.689
Description
This MIB reports the congestion status of the real server. A server can be in congested state due to high memory consumption, high CPU utilization or high number of clients being served by it. Congestion can cause delay in server response time. DFP (Dynamic Feedback Protocol) weight values are used as a metric to monitor the congestion of the server. This MIB generates notifications when congestion state is detected on the real server. DFP weight is calculated as follows BindingWeight=(Maxbindings-numberOfBindings)/Maxbindings CPUMemWeight=(cpu + mem)/32 Weight = BindingWeight*CPUMemWeight*dfp_max_weight Here, - Maxbindings is the maximum number of bindings allowed on the server. - dfp_max_weight is the maximum possible value of DFP weight (24). - numberOfBindings is the number of mobile bindings currently present with the server. The DFP weight at which congestion is detected is configurable. If the DFP weight of the system falls below this value, then the system is treated as congested and notification is generated.
