10 psi-notify is a minimal unprivileged notifier for system-wide resource
11 pressure using PSI. This can help you to identify misbehaving applica‐
12 tions on your machine before they start to severely impact system re‐
13 sponsiveness, in a way which MemAvailable, CPU graphs, I/O utilisation
14 graphs and other metrics cannot.

18 psi-notify does not take any options. If any are provided, a help mes‐
19 sage will be printed and psi-notify will exit.

23 You can optionally put configuration in ~/.config/psi-notify. Here's
24 an example that will check roughly every 5 seconds, and pop up a noti‐
25 fication when the configured values are exceeded:
26
27 update 5
28 log_pressures false
29
30 threshold cpu some avg10 50.00
31 threshold memory some avg10 10.00
32 threshold io full avg10 15.00
33
34 These are the default settings if no configuration is provided.
35
36 For more information about how these values are calculated, please see
37 the PSI documentation at ⟨https://facebookmicrosites.github.io/psi/⟩.

41 psi-notify requires Linux kernel 4.20+ and CONFIG_PSI=y. You will also
42 need a notification daemon that conforms to the Desktop Notifications
43 specification to receive the notifications.
