History - Aggregation
Another feature of the history and comparative history widgets is the ability to view aggregated (grouped) measurements through different calculations.
The available options for aggregation calculations are:
- Default
- Minimum: the resulting value is the minimum of all states or measurements recorded in a specific time interval.
- Maximum: the highest value of all states or measurements during a time period.
- Average (mean): the average of all measurement values recorded in a given interval is calculated.
State aggregation is an extremely useful tool for synthesizing and presenting device data in a more understandable and useful way. The different aggregation methods allow users to choose the strategy that best suits their analysis and decision-making needs. This functionality optimizes monitoring and facilitates the detection of patterns and important events in complex systems.
History - Granularity
State granularity is a feature that allows users to adjust the level of detail at which device state measurements are presented. This control over granularity provides crucial flexibility for monitoring, as users can choose how data is presented based on the context and analysis needs.
History - Disconnection Time
There are occasions when a device disconnects but measurements continue to be generated. When the device reconnects, the stored measurements from that device are automatically synchronized with the system, allowing the user to see the complete data sequence without manual intervention.
