New project ideas and questions about Mainframes

Hello,

I am a computer science undergraduate and I am totally new to mainframe and I thought they were a thing of the past until I discovered the OMP project Internship program. Turns out I was extremely wrong. I’d like to check on one of my ideas.

How different are the state of alerting and monitoring in mainframes than in typical server instances that we get from say AWS? I am currently working a lot with Nagios and Prometheus monitoring and alerting. Are there additional things that need to be monitored specially for mainframes?

What are the differences in running an OS in z/VM v/s my laptop?

Best,
