PSI-NOTIFY(1)

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.
