Netflow Traffic Analysis - slow chart load times

kclark over 14 years ago

I have seen this subject brought up before, but the answers didn't exactly fit my situation. We have NTA 3.5 running alongside NPM 9.5 SP2. NPM is speedy, NTA data is speedy, but NTA charts take 10-15 seconds *each* to display. NPM/NTA is running on a VM with 4 vCPUs and 4GB of ram. Our SQL Server is a Dual Quad-core 2.53Ghz server with 12GB of ram (10GB given to SQL) attached to RAID 10 disk. Based on performance data I've looked at on the host and VM level, I don't see any bottlenecks that would explain the poor chart performance. Is there a bug I'm missing, or any way to optimize chart performance?

Thanks,

-Kevin

My NTA summary page takes less than 5 seconds to load. We aren't running on a VM so I'm not sure if that has something to do with it or not.

Just curious how many endpoints you have reporting to NTA?

We are monitoring 300 interfaces across 6 devices. There are usually 10,000+ active nodes on the network at a given time.

You might try setting your default interval for for those charts to 5mins. I know that helped me out a lot.
