NAME

       psi-notify - notify on system-wide resource pressure using PSI

DESCRIPTION

       psi-notify is a minimal unprivileged notifier for system-wide resource pressure using PSI.
       This can help you to identify misbehaving applications on your machine before  they  start
       to  severely  impact  system  responsiveness, in a way which MemAvailable, CPU graphs, I/O
       utilisation graphs and other metrics cannot.

OPTIONS

       psi-notify does not take any options. If any are provided, a help message will be  printed
       and psi-notify will exit.

CONFIGURATION

       You can optionally put configuration in ~/.config/psi-notify.  Here's an example that will
       check roughly every 5 seconds, and pop up a notification when the  configured  values  are
       exceeded:

              update 5
              log_pressures false

              threshold cpu some avg10 50.00
              threshold memory some avg10 10.00
              threshold io full avg10 15.00

       These are the default settings if no configuration is provided.

       For  more  information  about  how  these  values  are  calculated,  please  see  the  PSI
       documentation at ⟨https://facebookmicrosites.github.io/psi/⟩.

DEPENDENCIES

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