Harvest-monitor is a lightweight daemon which uses custom iptables counters to do measurements on network traffic. This is an optional feature. If available, harvest-client will collect these measurements and report it to the server.
Harvest-monitor is a lightweight daemon which uses custom iptables counters to do measurements on network traffic. These counters are then accumulated in a SQLite database, where each row presents a day. This is an optional feature. If available, harvest-client will collect these measurements and report it to the server.

This is based on downstream sugar-toolkit and sugar-toolkit-gtk3 patches by Manuel Quiñones and Martin Abente.
This is based on downstream sugar-toolkit and sugar-toolkit-gtk3 patches by Manuel Quiñones and Martin Abente. These patches allow the activities to count the time (in seconds) for when it was opened. Only takes into account the time for when activity is the main screen. This is also a optional feature.

The precision of the time tracking can be improved by taking into account power management events and other sugar UI events. In order to do so, harvest-tracker must be used.
