Can I configure two server IPs for a single agent. The requirement is a single agent to send the data to multiple servers atleast two at any given time.
You might be able to configure an intermediate proxy, such as Squid, to do this for you. However I don't know Squid well enough to be able to say that this is definitely possible.
that'd break badly. agents and server are paired together uniquely. If you were able to have the same id's on both datbases it'd still lead to corruption in the database.
