10.4.5 Performance Logs
The Performance Log holds up to one-year’s worth of daily roll-ups with a minimum, maximum and
average value for key usage statistics. For systems, this includes: input voltage and current, and the
output voltage and current. For the controller, the CPU and memory usage are tracked.

To create the daily roll-ups, the Performance Log is rolling up second data into minute data, minute
data into hour data and hour data into daily data. The web displays previews of all four sets of data as
they are collected. In these previews, the horizontal axis shows the data sampled, not the time stamp.
Daily statistics with minimum, maximum, and average values can be exported for each log by clicking
the Export data to CSV button under the Days graph. Or you can export every log by clicking Export
All via Logs > Performance Logs .

If there is a clock error, indicating that the time and date is unknown, a
Performance Log will not collect
data.
