Hello,
Apologies if this has been answered elsewhere. I did a quick search and did not find it.
Is it possible to get a total flow count that is being received by Orion from within NTA? I really need this data.
From the above screen, click Performance Monitor and then you should see a page with a graph and a few items being polled. In the upper left, you should see a green + sign, this is for adding new counters. Scroll down until you find the counter for "SolarWinds NetFlow" and you should be good.
You can use performance counters for NTA service.
e.g.>
run perfmon
add counters from category SolarWinds NetFlow
you are interested in counters PDUs Procesed and PDUs Received
Unfortunatelly this is only for actual instance of netflow service.
That is exactly what I needed. Actually, the PDU per second. Thank you!
So, is ~1200 PDUs per second a lot? Because this is only from a single Packetshaper...
That is a fair amount. To give you an idea, in our stress testing, we begin our lowest tests with 9000 PDUs per second and go up from there. Of course it all depends, mainly on your SQL hardware and if this is just for one node, it wouldn't take many before you would get into a "stressed" situation. (Assuming your SQL hardware is like our lab machines)
You may want to monitor the Performance Counters on the SQL machine to get an idea of how it is handling it as you add more nodes for the NTA service to collect from.
Thanks,David
Thanks David. The primary polling engine seems to be handling those numbers fine. The only problem is that the NetFlowService.exe service on the polling engine continues to consume more and more memory until it eventually crashes (I suspect this is because it is throttling how fast it writes to the SQL db based on what that server load is). I was told in a different thread to open a case about this and will be doing so later today.
I've known that our SQL server has needed an upgrade since working with you last time. Work is progressing on that front. I may do a test with one of our SANs or simply order a new server with better disks. :-)
How exactly do you add the SolarWinds NetFlow category/counters in perfmon?
Our NTA module is running on a Windows Server 2008 box and unfortunately I have no expereince with perfmon.
TIA
Just go to Start -> Run and type in perfmon and follow the info above.
I know how to launch perfmon but how do I "add counters from category SolarWinds NetFlow"?
Below is the screen I see when I launch perfmon on the NPM/NCM/NTA server (we have a seperate SQL server).
