Hi:
Please, what does mean the response time in this chart ?
the time in milliseconds it took for the polling engine this object is assigned to ping the object and the response to get back. i.e. ping response time from the poller to that node.
and what determines this high response time ?
Higher period of time from NPM to the devices or interface it is pinging. High response time can be due to all kinds of things... routing changes... topology changes... distance... hops the packet takes between... any link along the path could slow down pings time to return.
