Trackers help watch mission-critical server data in real-time. All trackers are shown together in a single table (e.g. Trackers window in AggreGate Client) to enable efficient monitoring. Trackers use color highlighting to indicate their state.
Here is what the trackers table looks like in AggreGate Client:
The basis of a tracker is a tracked expression written in AggreGate Expression Language. This expression may refer to some server data or to data originated from hardware Data Terminals. A simple tracked expression may be used to monitor some value directly, while more complicated ones help track combinations of several values. For example, a tracker can be easily set up to watch dew point temperature calculated by temperature and absolute humidity measurements coming from different sensors.

Every user has his own set of Trackers. |
The value of each active tracker expression is recalculated periodically, as specified by the Check Period property of the tracker.
