Trackers

Data tracking

Trackers help to watch mission-critical server data in real-time. All trackers are shown together in a single table to enable efficient monitoring.

Each tracker is based on an expression, which can refer to some server data or data originated from devices and external data sources. A simple expression can be used to monitor a value directly, while a more complicated one can track a combination of several values. For example, a tracker can be easily set up to watch the dew point temperature calculated by temperature and absolute humidity measurements coming from different sensors.

Tracker Statuses

Tracker status lets system operators quickly check the state of a tracker by highlighting it in the tracker list. Statuses can help to detect trackers that indicate warning and critical conditions of monitored values. It is possible to associate an unlimited number of user-defined statuses with every tracker.

Value of each active tracker's expression is recalculated periodically. Stateless and disabled trackers may be optionally hidden from the list.

Tracker list of the unified console shows the trackers collected from several servers, facilitating supervision of a large distributed AggreGate installation.
