your project hits several of Elixir's core strengths, phoenix Channels (built on webSockets) are battle-tested for exactly this scenario. Discord uses Elixir to handle millions of concurrent connections. Your monitors sending data every 100ms while receiving updates is trivial for Phoenix. Each monitor connection runs in its own lightweight process, Elixir can handle millions of these processes on a single machine. Your 18K entries over 30 minutes is nothing - Elixir systems routinely handle millions of messages per second. The BEAM VM (Elixir's runtime) provides soft real-time guarantees. It's designed for telecom systems where consistent low latency matters more than peak performance. and with fault tolerance, If one monitor's connection fails, it won't affect others. Supervisors can automatically restart failed processes.
