Q & A on Router Statistics in HPOpenView Q: I'm using Optivity on HPOpenView.. so they have this 5 groups of counters for routers.. i.e Group 1 (IP Utilization%, IP Error%, IP Gauge) Group 2 (Packets Forwarded) Group 3 (In Datagrams) Group 4 (In Header Errors, In Invalid Destination Address, In Unknown Protocol, In Lack Buffer Space)< Group 5 (Out lack Buffer Space, Out No Route) these counters.. what do they represent? A: 1 Statistics about IP datagram traffic 2 A count of all packets including IP and other protocols 3 Counts of IP datagrams that have arrived over each interface 4 A count of errors in incoming traffic, including valid packets that were discarded because the router did not have space in memory 5 A count of packets discarded because the router lacked output buffer space or did not havea route. Q: could you pls elaborate on counters or which counters used to check network performance... A: A router is not performing well if it runs out of buffer space or if there are other errors. As long as there are no errors, most managers focus on ``packets forwarded'' as a measure of performance.
