Dear community,
existing situation:
company with two separated sites - one office and one datacenter site connected via WAN infrastructure
NPM application installation together with separate database server on office site.
current NPM deployment monitors office and datacenter equipment (so polling from NPM main poller located on the office site)
requirement:
new NTA installation, to be able to collect netflow data from datacenter core/internet routers.
the point is, we want to avoid netflow data from being routed over the WAN connection from datacenter to office.
so the netflow collector and the flow database must be located on the datacenter site.
the NPM poller should stay on the office site because most equipment is monitored there....
question:
is it possible to install an additional NTA polling engine (without NPM polling engine) on a second site and also run the flow database locally on the DC site?
if yes: how exactly are the traffic patterns between additional polling engine <--> flow database <--> NPM SQL DB <--> Web UI ?
and what type of traffic patterns can we expect on the WAN leased line in this type of setup?
there are some loose hints about additional poller and external polling database with NTA,
but unfortunately I am not able to find an explicit deployment guide confirming that type of design...
Thanks for all infos!
Cheers
