I see in the status panel on the Master and on WinNUT-Client that the
"Input Voltage" and "Frequency" values are reported.
These are values that I am interested in statistic, as well as others,
for example when the current has failed.
Sometimes we find systems stopped and no one knows if, when and how
many times the power has failed or if there has been a voltage overload.
As well as output I would like to keep a statistic of the load
connected to the UPS to know when someone has connected something else
to the UPS and all the shutdown parameters are then skipped because
the load was excessive.
If there isn't already something that does this, I would like to
create a script with commands to read some values and put them into a
file which I will then pass to a spreadsheet.
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@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.
What should MRTG help me with UPS?
it can create nice graphs.

Do you mean presence of wall power? That would be `upsc`
momentarily asking for `ups.status`. For its quality -
`input.voltage` etc. assuming your UPS reports it.
For history - some monitoring tool (MRTG etc.) doing the same
continuously. Maybe `upslog` would do.

Is there a tools that gives me a history of the power in the wall?
If not, how can I get the values of the power in the wall
with an online command?
