Troubleshooting tools for remote VPN Users

What are some excellent tools out there for Remote VPN users? I’m desiring something like a smokeping that runs hidden as a background process on the workstation, that we could remotely manage and point at different targets and it would track instances of packet loss, jitter, etc, and let us review history data for days if not weeks back.

At this point, lacking a tool like this, I find remote VPN users connectivity complaints as very difficult to troubleshoot. At this point we’re kind of relying on saying things like “well, this isn’t happening to the other 3k users on the vpn so it must be you,” which quite frankly as an engineer doesn’t really satisfy me as a good answer.

I want to show charts and data that point out “see you lost connection to our network briefly, you need to call your home ISP.”

How have some of you experts in heavy WFH environments handled persistent complaints? Complaints range from “I get kicked off all the time,” to just plain “it’s so slow on the vpn!”

Of course we’re able to vet every inch of our network checking for congestion and errors along every interface through our ingress and vpn concentrator, we’re able to check CPU/Memory for every device the traffic goes through... what we are not able to check did this users ISP drop traffic, are they taking errors at some peering point to reach our ASN?

We need better tools I think!
