Trying to receive S-Flow data from an F5 self IP

Hi Thwackers,

We have an F5 load balancer that we're monitoring in Orion NPM. We added it using it's management interface IP address as the polling IP.

We'd now like to configure the F5 to send S-Flow data to Orion NTA. Apparently, the F5 can only send S-Flow data from one of its 'self-IP' interface IP addresses (not the management interface IP address). From what I've read in the NTA documentation, it sounds like Orion needs to have the node added to NPM first, and then you can start receiving S-Flow data from that same IP address. In our case though, these two IP addresses are different.

I see two options:

1) Edit the node in Orion NPM to change the polling address from being the management IP address to the self-IP address

2) Create an additional node in Orion NPM, using the self-IP of the F5 and give it a different name e.g. "F5-LB-Self-IP"

I am new to NTA and F5, so am wondering if anyone in the community has been in this situation before and has any experience or tips/advice?

Thanks,

ollydrew

Those are definitely two options, but NTA should help you resolve this. For example, if you're already sending that data from F5 to NTA you might see the alert in this KB article:

Not primary NPM node IP address - SolarWinds Worldwide, LLC. Help and Support

If you do, you can follow this article to allow monitoring flow from unmanaged interfaces:

Hi jrouviere,

Apologies for not having responded sooner - the colleague who's the F5 admin is on holiday for a few days, so I haven't looked at this for a while. They'll be back on Monday, so I'll pick this back up then.

I read the articles that you pointed me at, and reviewed the "Allow Matching Nodes by Another IP Address" setting. It was already enabled. I'll post back next week to let you know how we get on.

Thanks for your help,
