## Apcupsd DATA Logging

This feature is somewhat outdated and not often used.

### DATA logging

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, BatteryVoltage, LineFrequency, UPSTemperature,AmbientTemperature,Humidity,LineVoltage

Any value that is not supported by your UPS such as AmbientTemperature and Humidity will be blank; the commas before and after that field will still be output.

An actual example from the log file is:
