Any tips on monitoring fully redundant network (with failover)using NPM?
As I understand, NPM sends icmp and snmp request and decide if a node is down after 8 or more RTO (please correct me if I'm wrong)?
NPM determines that a node is down if it misses a series of pings, but if the first ping is missed, it then goes into fast poll mode and quickly does a series of pings, so it doesn't take long to call it down.
Can you elaborate on what you mean about monitoring a rully redundant network?
Fail over - when 1 router will down the load will transfer to the other router. so when that happen, only several RTO then will return to UP again
