Getting invalid memory address or nil pointer dereference. Setup environment variables, database etc. Same error whether IDM or SCM.

I would also recommend that you upgrade your go toolchain and re-build both rtlamr-collect and rtlamr. Around about go 1.10 or so, there were some significant improvements to compiler optimizations and performance on ARM systems.
