DESCRIPTION

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.

OPTIONS

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.

CONFIGURATION

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/⟩.
