A very very very long time I used a script similar to the one below in 
order to monitor an UPS and alert me by mail if the current temperature 
exceeded a specific threshold. If you adjust the parameters for awk ( or 
instruct upsc to report only what you need - in my case I wanted rounded 
values so I did not use the syntax "upsc <UPS> ups.temperature"  ) you 
can monitor whatever variables you are interested in.

----- cut here -----

#!/bin/bash

CURTMP=`upsc ablerex at db | awk  '/ups.temperature/ {print rounded = 
sprintf("%.0f", $2)}'`
HIGHTMP="40"

MAILTO=""
DEST="tech@$DOMAIN"

if [ $CURTMP -ge $HIGHTMP ]; then

echo "Current UPS temperature: $CURTMP" | mail -s "UPS temperature > 
40"  $DEST  > /dev/null

fi

----- end here -----

Note that upslog is probably a better solution for you because it can do 
continuous monitoring, writing to a file with specific formatting while 
also selecting only the variables you are interested in

Unfortunately I no longer have access to the machine where I used it so 
I cannot copy/paste that old script.

it can create nice graphs.
