This project aims to deliver Pressure Stall Information (PSI) alerts via standard Linux graphical desktop (through libnotify compatible daemons and CLI programs), and email (email-to-SMS is also supported). This can alert the system administrator of CPU, I/O, or Memory (RAM) pressure in near real time.

PREREQUISITES

A Linux system with kernel 5.2.0 or greater
systemd
zsh
ssh (OpenSSH, for desktop notifications)
psi-by-example (a modified version of this is included in this project as a submodule)

TODO

finish INSTALL section
- figure out how we're actually going to build all submodules
- and install them
finish CONFIGURE section
- about defining an instance and editing it
  - sudo systemctl edit psi-alerts@<user>.service
