What does average response time mean that indicates in NPM
can I calculate more specific instead of a round trip from the Orion NPM host to the target device and back. such as from serial router source
any body can explain ?

Average response time is just as you described; the average amount of time it takes for the NPM server (or polling engine) to receive an ICMP reply from a given device. Being that it's ICMP based, it is a measurement of round trip time. The ability to strategically source the measurement from a particular device is not something that Orion can do today. All requests are sourced from the polling engine to which a given device is associated.
This has been brought up a couple of times before, but I'm not sure if SW is considering this as an enhancement for a future release.
If your environment reqiures more than one polling engine, strategically placing these and distributing load to them accordingly may help with accuracy. I have an extranet with a ton of customer connectivity that we own. My next polling engine will live within that DMZ and poll those devices in that DMZ only. This eliminates firewalls and other extraneous hops that can skew results.
I would really love to see a CiscoWorks IPM-like product built into Orion utilizing Cisco SLA where you can set up ping/tcp tests between any deviceslike 2 ends of a serial connection.BB
I agree. I believe they are looking at implementing a similar mechanism for measuring synthetic VoIP traffic, but I don't know the specifics.
