could you please add a little bit info?
1.From how many nodes do you currently receive netflow?
2.What is your average flows per second? (check performance counter 'PDUs processed per second' in 'SolarWinds Netflow Averages' category using perfmon)
3.How many nodes exporting netflow would you like to add?
4.How many flows per second do you expect from those new nodes? (roughly)
Hi - thanks for your reply.
Some rough answers:
1. About 20 nodes so far
2. Seems to average at about 3000 PDUs/sec
3. 100-120 new nodes to add
4. Similar levels to the existing ones - so somewhere between 100-150/sec
Maybe there's a formula to estimate load?
Ok, so it seems you will end up with 6-7 times bigger load than you currently have. While splitting the load evenly between main and aditional receiver should be enough on Orion side, the biggest problem use to be on DB side. Be prepared on ~ double size of DB (mainly FG3) + increase in RAM consumption (I would recommend adding some extra RAM, but don't know your current SQL server resources).
Wouldn't NTA 4.x be recommended here?
I would think so, you definitely get better NTA performance out of 4.X. Rather than have a dedicated poller, put your bucks into the new NTA no-sql database server that is required for it.
