Broker Connection Count, Connections/Second, and CPU Utilization
brokerConnCount is the number of established TCP connections
used for load balancing. This number aggregates all
serviceConnCnt values in the serviceTcpTable.
brokerCps is the number of TCP connections/second established
by the Director.
brokerCps aggregates all serviceCps values in
the
serviceTcpTable.
brokerCpuUtil returns the current CPU utilization of the
Director. Its value can be from 0 to 100%.
Trap thresholds are available in the MIB for
brokerCpuUtil,
brokerConnCnt.
Trap thresholds for Director CPU utilization can be configured such
that if the Director CPU utilization reaches a value, a trap is sent.
When
brokerCpuUtil reaches brokerCpuUtilHiWater, a
brokerCpuUtilAlert trap is sent. While in alert, if
brokerCpuUtil dips to brokerCpuUtilLoWater, a
brokerCpuUtilNormal trap is sent. High- and low-water
thresholds provide hysteresis and prevent the spurious generation of
traps. If the high water threshold is set to 0, no traps are sent.
Trap thresholds for Director connection count can be configured such
that if the connection count reaches a value, a trap is sent. The traps,
brokerConnCntAlert and brokerConnCntNormal and
applicable thresholds work similarly as described above for Director
CPU utilization.
Trap thresholds for Director connection/second can be configured
such that if the connection/second rate reaches a value, a trap is sent.
The
brokerCpsAlert and brokerCpsNormal traps and
applicable thresholds work similarly for the SA8250’s CPU
utilization.
Director and Redundant Director Operational State
Operational state of the Director can be monitored through
operationState. Whenever the value of operationState
changes, the
operationStateChanged trap is sent. The
operational state of the redundant Director in a serial-cable failover
configuration is monitored through
redundantBrokerState.
The traps
redundantBrokerUp and redundantBrokerDown
are sent to alert the administrator of any changes in the availability of
the redundant Director.
