On IPSO the counter for packet drops is almost similar with the cisco drop counters. It is really detailed and can show us many kind of drops.
To see if the number iof drops raises we have to check it 2-3 times when the issue arises. I guess with snmp we can monitor that value as well..
In this example the eth0 interface is checked for drops. with the ‘repeat’ command -installed under IPSO- can we set how much time we need the output of the statistics. That way we can see if the counter increases or remains on the same value.
