What are my options then - try to extend the functionality myself?

I can't work out the relationship between /proc/net/dev and if{In,Out}Errors : these are the snmp numbers: IF-MIB::ifDescr.5 = STRING: eth3 IF-MIB::ifInOctets.5 = Counter32: 652976496 IF-MIB::ifOutOctets.5 = Counter32: 267700325 IF-MIB::ifInErrors.5 = Counter32: 76 IF-MIB::ifOutErrors.5 = Counter32: 0 IF-MIB::ifInDiscards.5 = Counter32: 0 IF-MIB::ifOutDiscards.5 = Counter32: 0 # cat /proc/net/dev Inter-| Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed eth3:652934800 213413680 445 0 3817 4262 0 0 267697903 67372040 0 0 0 0 0 0 The minor difference in the in/out counters can be explained by the 1-2 seconds between my snmpget and 'cat /proc/net/dev', but the ifInErrors.5=76 doesn't seem to correspond to anything from /proc/net/dev ?? -- Per Jessen, Zürich (16.1°C) ------------------------------------------------------------------------------ Better than sec?
