I have started working with Juniper RPM probes some time ago and needed to add its statistics to SolarWinds.
SolarWinds added support for RPM probes in VoIP and Network Quality Manager (VNQM) module, however every time I tried to use it I got strange results.
The probes were always in Unknown status, the VNQM website was unresponsive or it timed out. My last test was with Orion 2024.2.0 and it still had issues.
I talked with SolarWinds Support, but I was not able to receive a quick solution and the deadlines were approaching.
So, I needed to create my own solution.
All the configuration process and walkthrough is available on my YouTube channel. Please subscribe
