Hey Gene,

The syslog entry should have one-second resolution in the timestamps, and you could use the "EXEC" option in "NOTIFYFLAG" in upsmon.conf to call your own script on the ONBATT and ONLINE events (which would allow you to pass whatever message you want to "wall").

However, for a one-second glitch, many of the NUT drivers might miss that in their polling cycle. (This usually isn't a problem, since an UPS with a good battery should be able power the load for much longer than one poll interval.)

This is one of the few cases where a "dumb" contact-closure UPS and a dedicated serial port monitor program might be a better fit. Which driver(s) are you using?
