Device Setting Statistics

Iotellect Server allows you to create statistical channels for device setting variables. Statistical channels keep long-term aggregated history for numeric values such as traffic, power consumption, voltage, noise levels, temperature, people counters, and whatever else.

The device's statistical channels may be managed using Edit Device Properties action. It provides access to Statistics () table containing channel definitions. Each definition comprise:

• Channel Name. This is a unique ID of the channel that is used to refer it, e.g. when building charts.

• Variable. Name of variable the channel is based on. Simply speaking, Iotellect Server generates a new Primary Data Point for the channel each time this variable is changed.

• Enabled. Controls whether the channel is active and collects data. Default channels should be disabled instead of deleting them in order to prevent their re-creation.

• Properties. These are parameters of statistical data collection, storage and processing.

To view brief statistics for all channels, run View Status () action and switch to the Statistics tab. Note that only channels with the Show In Statistics option enabled will be visible.

If the channel is using keys, the Dataset summary dialog will be shown first, allowing you to select a Dataset (key) to view its brief statistics.

To view detailed channel statistics, launch the Configure Device () action, right-click on a variable (setting) and select View Statistics (). The list of channels associated with the variable will pop up first.

• Select a channel to view the list of enabled Archives:

• Select an Archive to view its detailed statistics grouped by time periods.

An alternative way of viewing device setting statistics is using the global View Channel Statistics action.

Global server configuration defines the list of default statistical channels that are applied for newly created devices. Each global channel configuration includes name of variable. If a new device has variable with such name, a new channel is created to store variable's value for this device. Channel properties are copied from the default channel definition and may be fine-tuned manually later on.
