Statistic Description
com-io-group.io-tm-min Minimum latency on this channel group in last 5 seconds (updated every 5
seconds).
com-io-group.msg-b-in Always returns zero.
com-io-group.msg-b-out Total bytes sent on this channel group.
com-io-group.msg-cnt-in Always returns zero.
com-io-group.msg-cnt-out Total messages sent on this channel group.
Table 26. COM Path Statistics
Statistic Description
com-path.ping-count Number of ping packets sent. These are used to help calculate latency.
com-path.ping-late Number of ping packets that took too long.
com-path.ping-lost Number of ping packets lost.

com-path.posted-send-ack Number of ACK buffers posted. (ACK buffers queued for transmission).
com-path.posted-send-ctl Number of control buffers posted. (Control buffers queued for
transmission).
com-path.rtt-avg Average round trip time for data to travel along the path.
com-path.rtt-max Max round trip time for data to travel along the path.
com-path.rtt-min Min round trip time for data to travel along the path.
com-path.send-bytes Number of data bytes send along this path. This includes data plus
UDCOM headers.
