NAME         top

       pcp-rocestat - Reports statistics for nVidia RoCE devices.

SYNOPSIS         top

       pcp [pcp options] rocestat [--hw_stats|--lane_stats]

DESCRIPTION         top

       The pcp-rocestat tool utilizes ethtool counters for each device
       and reports throughput per priority queue.  By default pcp-
       rocestat reports live data for the local host.  It has the ability
       to analyze data from PDP archives as well.

PCP ENVIRONMENT         top

       Environment variables with the prefix PCP_ are used to
       parameterize the file and directory names used by PCP.  On each
       installation, the file /etc/pcp.conf contains the local values for
       these variables.  The $PCP_CONF variable may be used to specify an
       alternative configuration file, as described in pcp.conf(5).

       For environment variables affecting PCP tools, see
       pmGetOptions(3).
