DATA Logging
This feature is somewhat outdated and not often used.
Data logging consists of periodically logging important data concerning
the operation of the UPS. For the definitive definition of the format, see
log data() in apcreports.c. The format varies according to the UPS model
and the information available from the UPS.
For UPS models, NBKPRO, SMART, SHARESMART, and MATRIX, the
output is written in a format very similar to what PowerChute writes. That
is:
MinLineVoltage, MaxLineVoltage, OutputVoltage, Bat-
teryVoltage, LineFrequency, LoadPercent, UPSTempera-
ture,AmbientTemperature,Humidity,LineVoltage, BatteryCharge,toggle
Any value that is not supported by your UPS such as AmbientTemperature
and Humidity will be blank or possibly as 0.0. In any case the commas
before and after that field will still be output. The toggle value alternates
from 0 to 1 on each line. This was added at user request so that no two
adjacent samples are identical.
An actual example from the log file is:
