System Load Statistics (Radio Meter)
The radio meter command prints out a table of measurements that indicate the current load on
the system. These statistics are only available at the CCU. The load statistics are summarized
in Ta ble 90. System Load Statistics are not available through the WaveRider MIBs.
Table 90 Load Statistics (Radio Meter)
Notes:
All counters are continuous; that is, they are never zeroed, except if the unit is reset or
power cycled.
Payload and poll counters can roll over after a minimum of 50 days.
Byte counters can roll over after a minimum of 4 hours.
Statistic Description
Time
Value of the CCU’s internal 32-bit microsecond timer at the instant the messages
were taken.
Time rolls over to 0” about every hour and eleven minutes.
Fw Pyls
Number of payloads transmitted from the CCU to EUMs in this class/level,
including retries.
Fw Bytes
Number of bytes of payload transmitted from the CCU to EUMs in this class/
level, including retries.
Rev Pyls
Number of payloads transmitted from EUMs in this class/level that are correctly
received by the CCU.
Rev Bytes
Number of bytes of payload transmitted from EUMs in this class/level that are
correctly received by the CCU.
Max Vio
MaxIPS Violations - Number of times the CCU has not polled an EUM in this
class/level within the inter-poll space defined by the EUM’s grade of service.
Ideal Vio
IdealIPS Violations - Number of times the average inter-poll space for EUMs in
this class/level has been more than 25% higher than the ideal inter-poll space
defined by the grade of service.
#EUMs
Number of EUMs in the class/level at the instant in time the load statistics were
collected. The broadcast channel counts as one.
Avg IPS
Current low-pass average inter-poll space, in microseconds, for the class/level at
that instant in time, which corresponds to the current polling rate for EUMs in that
class. If no EUMs are currently in the class, it is the average taken at the time the
last EUM exited the class.
Total Polls Number of times the CCU has polled an EUM in the class/level.
Empty Polls
Number of times the CCU has polled an EUM in the class/level and did not either
transmit or receive a payload.
