I'm running Orion 9.1 with netflow 3.1(will upgrade to 9.5 and netflow 3.5) on a Dual-Core ADM Opteron 2.8GHz, 4.00G of RAM server. The standby orion will be configure later for high availability. The sql server is on vmware and has the same spec with Orion server.
Orion currently monitor about 76 applications.
Netflow will be monitor about 3600 remote wan Cisco routers
Orion server and sql server locate at the main datacenter
1. How much bandwidth does Netflow use to collect data from remote routers/switches? Netflow admin guide does not give much detail on how much bandwidth and min/max bandwidth recommandation.
2. Does my server orion enough horse power or I need more ram or better processor? Do I need a better server?
3. Sql server(the same spec with Orion server) capable handle the data collecting workload for 3600?
4. What're some of the way to optimize Netflow bandwidth over on wan Cisco routers/switches?
Can someone please share your Orion/Netflow and Sql servers spec and how many monitored applications and routers.
THanks
