# eventer rules template — copy/paste into ~/.config/linux_post_install/event.env
|
|
# (or add each line via: pos system event-trigger config).
|
|
#
|
|
# One independent rule per line. Grammar:
|
|
#
|
|
# "<message>" if <check-command> <op> <threshold>
|
|
# <check-command> <op> <threshold> (no message → auto-composed)
|
|
#
|
|
# <message> optional quoted alert text (quote-stripped)
|
|
# <check-command> any shell command; first numeric output is the value
|
|
# <op> > < >= <= == !=
|
|
# <threshold> number with optional unit suffix: 60c, 80%, 10g
|
|
#
|
|
# Rules alert once on false→true (plus one recovery message on true→false)
|
|
# via lib/notify.sh — Telegram by default. State is tracked per rule in
|
|
# ~/.local/share/linux_post_install/eventer/state/ (keyed by rule-line hash).
