Hello fellow sufferer.

Not quite the same on my end but it ended up in the same place. When I started there were already two instances running (one for the parent company and one at my location, which had gotten acquired). Maybe a hundred nodes all together, and our job was just responding to alerts in a mostly out of the box setup. Then my boss got sick of trying to work around limitations of that setup and demanded admin access so our team could at least make adjustments. Which eventually turned into me being asked to add nodes, which turned into me being the primary administrator. Which was actually pretty sweet for a bit because I got to learn a lot, both about the software and the company. Finally convinced management to merge the two installations rather than rely on that EOC garbage.

Then the acquisitions started rolling in.

By the time I walked out there were 2000+ nodes in a dozen locations, and it was still just me and somehow still just a side job.

Orion has its faults but after migrating so many acquisitions from a handful of other platforms I still prefer it. Everything seems like it's optimized for small installations and/or specific platforms. When shit gets that big you need a team to run it properly. Which is why I'm allowed to say "Solarwinds" in my house, but guests are asked to leave if they mention the C-suite as anything but sociopathic leeches.
