C H A P T E R 7 Using SNMP

239

Trap thresholds for service connection can be configured such that if

the connection/second rate reaches a value, a trap is sent. The

serviceCpsAlert and serviceCpsNormal trap and applicable

thresholds work similarly for service response time.

Broker Connection Count, Connections/Second and CPU Utilization

brokerConnCnt 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 brokerCpuUitlLoWater, 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 SA8220’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.
