Error description
nmon ( n ) and other tools uses perfstat_netinterface() to fetch network stats . For some interfaces ( ETHERCHANEL ) the values provided by the subroutine is stale ( not updated ) as the underlying kernel extension is providing stale values. The network stats shown by nmon is all zeros since nmon collects stats over a peroid of time ( which is not being updated) and calculates delta .
Local fix
