Table 16. Director statistics (continued)
Statistic Type Description
director.fe-ops-act
"type: reading, units: counts,
arguments: none "
Front-end operations
active
Number of active outstanding I/O operations on the
director’s front-end ports.
director.fe-ops-q
"type: reading, units: counts,
arguments: none "
Front-end operations
queued
Number of queued outstanding I/O operations on the
director’s front-end ports.
director.fe-ops-read
"type: counter, units: counts/second,
arguments: none "
Front-end reads Number of reads on the director’s front-end ports.
director.fe-ops-write
"type: counter, units: counts/second
arguments: none "
Front-end writes Number of writes on the director’s front-end ports.
director.fe-read
"type: counter, units: bytes/second,
arguments: none "
Front-end reads Number of bytes read from the director’s front-end
ports.
director.fe-write
"type: counter, units: bytes/second,
arguments: none "
Front-end writes Number of bytes written to the director’s front-end
ports.
director.heap-used
"type: reading; units: percentage,
arguments: none "
Memory Percentage of memory usage on the director.
director.per-cpu-busy
"type: reading, units: percentage,
arguments: none "
CPU busy The total utilization (user and system) of each CPU in
the director.
director.msg-send-ops number of operations The total number of messages sent from this director.
director.msg-max-lat Maximum latency The maximum latency of messages sent from this
director.
director.msg-min-lat Minimum latency The minimum latency of messages sent from this
director.
director.msg-avg-lat Average latency The agerage latency of messages sent from this
director.
Table 17. Front-end director (fe-director) statistics
Statistic Type Description
fe-director.aborts
"type: counter, units: counts/second,
arguments: none "
Front-end operations Number of aborted I/O operations through the director’s
front-end ports.
fe-director.caw-lat
"type: bucket, units: microsecond,
arguments: none "
CompareAndWrite
operations latency
CompareAndWrite latency in microseconds on the
specified director’s front-end ports. The latency bucket
is reduced to three buckets from 0 to maximum instead
of 64 latency buckets collected within the metro node
firmware.
fe-director.read-lat Front-end director read
latency
Read latency distribution in microseconds on the
director’s front-end ports.
