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
.
