We must have a mechanism by which we can retrieve real-time performance statistics from a monitored system. This data must consist of, at minimum, the following:

CPU usage (load average is fine)
Memory and Swap usage
Disk usage for all physical mount points
- Can exclude EFI partition for systems which use one
Uptime
Process count
Temperatures for physical computers
Network interface details
- Name
- MAC address (if applicable)
- IP addresses
- I/O rates

Some ideas of how to implement:

SSH-based polling
- Pros:
  - No software required on systems
  - Easy to provision new systems
- Cons:
  - Either constant reconnects (pollutes logs) or perpetual connections (security risk?)
  - Likely low polling rate
  - Server does all the work
Custom daemon on systems
- Pros:
  - Easily extensible
  - Can perform all tasks required
  - Can vary report rate based on system load
- Cons:
  - Requires software installed on systems
  - Extra load on individual systems
