Table 24. COM cluster I/O statistics
Statistic Description
com-cluster-io.avg-lat
type: reading, units: microseconds, arguments:
cluster-id
Average latency in microseconds of all I/O from the local cluster to the
other cluster in the last query period. Takes a cluster number as an
argument

Maximum latency in microseconds of all I/O from the local cluster to the
other cluster. Takes a cluster number as an argument.
com-cluster-io.min-lat
reading, units: microseconds, arguments: cluster-
id
Minimum latency in microseconds of all I/O from the local cluster to the
other cluster. Takes a cluster number as an argument.
com-cluster-io.send-ops
type:reading, units: none, arguments: cluster-id
Number of I/O send operations to the cluster.
com-cluster-io.ops-active Current outstanding messages to a site.
com-cluster-io.bytes-active Current outstanding bytes to a site.
com-cluster-io.bytes-queued Current queued bytes to a site.
com-cluster-io.ops-queued Current queued messages to a site.
Table 25. COM I/O group statistics
Statistic Description
com-io-group.io-tm-avg Average latency on this channel group in last 5 seconds (updated every 5
seconds).
com-io-group.io-tm-cnt Messages sent on this channel group in last 5 seconds (updated every 5
seconds).
