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This feature is somewhat outdated and not often used.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 verysimilar to what PowerChute writes. That

is:

MinLineVoltage, MaxLineVoltage, OutputVoltage, Bat-

teryVoltage, LineFrequency, LoadPercent, UPSTempera-

ture,AmbientTemperature,Humidity,LineVoltage, BatteryCharge,toggle

Any valuethat is not supp ortedby 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:

Nov 2 12:43:05 matou apcupsd[23439]: 224.9,227.5,226.2,27.74,50.00,100.0,30.6,,,226.2,50.0,1
