NOTIFYMSG type message
upsmon comes with a set of stock messages for various events. You can change them if you like.

NOTIFYMSG ONLINE "UPS %s is getting line power"
NOTIFYMSG ONBATT "Someone pulled the plug on %s"
Note that %s is replaced with the identifier of the UPS in question.

The message must be one element in the configuration file, so if it contains spaces, you must wrap it in quotes.

NOTIFYMSG NOCOMM "Someone stole UPS %s"
Possible values for type:

ONLINE
UPS is back online

ONBATT
UPS is on battery

LOWBATT
UPS is on battery and has a low battery (is critical)

COMMBAD

NOTIFYFLAG type flag[+flag]…

NOTIFYFLAG ONBATT SYSLOG+WALL+EXEC
Possible values for the flags:

SYSLOG
Write the message to the syslog

WALL
Write the message to all users with /bin/wall

EXEC

IGNORE
Don’t do anything

If you use IGNORE, don’t use any other flags on the same line.
