History

The History view presents sensor values, sensor value events, and status messages of devices and their sensors graphically over time.

In order to record data over time and make data progression visible in the History view, several requirements need to be met:

1] A MADRIX KEY with a valid MADRIX RADAR big data license needs to be connected to the software.

2] PostgreSQL Server needs to be set up as database management system.

3] The Store History settings need to be activated in the Options.

From	Allows you to define the exact beginning of the time interval that is shown as data graph. When navigating in the graphical view, this field will be updated accordingly and automatically.
To	Allows you to define the exact end of the time interval that is shown as data graph. When navigating in the graphical view, this field will be updated accordingly and automatically.
Sensor Values Series	Shows or hides all recorded sensor values. [This includes Present Value Series, Recorded Values Series, Detected MIN/MAX Series.]
Present Value Series	Shows or hides all sensor values that were received based on regular RDM requests sent to the devices. Learn more »Timing
Recorded Values Series	Shows or hides all sensor values that were recorded by a device itself. A device needs to support this feature. Learn more »Sensors
Detected MIN/MAX Series	Shows or hides all Min/Max Detected sensor values, which are the lowest or highest values ever recorded for a sensor. A device needs to support this feature.
Sensor Value Events	Shows or hides all reported sensor value events. [By default, this includes Critical, Validation.]
Critical	Shows or hides all critical sensor value events. - If this category is shown depends on your settings. - By default, sensor value events are assigned to the categories Critical or Validation in the Event Configuration. - You can freely rename categories or assign new categories. - Learn more »Event Notifications
Validation	Shows or hides all validation sensor value events. - If this category is shown depends on your settings. - By default, sensor value events are assigned to the categories Critical or Validation in the Event Configuration. - You can freely rename categories or assign new categories. - Learn more »Event Notifications
Status Messages	Shows or hides all recorded status messages of the device. [This includes Advisory Hints, Warnings, Errors as defined by the RDM standard.]
Advisory Hints	Shows or hides all advisory status messages.
Warnings	Shows or hides all warning status messages.
Errors	Shows or hides all error status messages.

You can easily navigate within the data graphs and adjust the view according to your needs.

Left Mouse Click + Hold + Move	Allows you to move freely along the X-axis and Y-axis.
Mouse Wheel	Quickly zooms in and out in order to narrow or enlarge the shown time interval. This determines the level of detail. Zooming in or out may group several data points, status messages, or events into one data point in order to declutter the graph. The tooltip will then include all items combined.
Ctrl + Mouse Wheel	Activates only the horizontal zoom and scales only along the X-axis.
Ctrl + Shift + Mouse Wheel	Activates only the vertical zoom and scales only along the Y-axis.

▪Right Mouse Click - Perform a click with your right mouse button on an entry.

▪In order to show historical data, you first need to
- Select a single device [in the Devices View].
and
- Select a single sensor of this specific device [in the Sensors View].

▪The following data will then be shown:
- Sensor values of the selected sensor.
- Sensor value events of the selected sensor.
- Status messages of the selected device.

▪Present Values will be shown as blue line [trend line] with blue dots [recorded data points].

▪Recorded Values will be shown as gray line [trend line] with gray dots [recorded data points].

▪MIN/MAX Values will be shown as black line [trend line] with black dots [recorded data points].
- Mouse-Over - Hover with you mouse over such a dot and MADRIX RADAR will show a tooltip that includes the timestamp as well as the sensor value.
- If a data point includes several sensor values, the average will be calculated for Momentary Values as well as Recorded Values. The lowest or highest value will be used for Min/Max Values.
- A gradient [red-orange-yellow-green] will be drawn between value minimums and maximum and therefore include a helpful graphical representation of the current status. Learn more »Sensors

▪Sensor value events will be shown as dashed/dotted, vertical lines:
- In purple.
- Mouse-Over - Hover with you mouse over such a line and MADRIX RADAR will show a tooltip that includes the timestamp [YYYY/MM/DD HH:MM:SS] as well as the event.

▪Status messages will be shown as dashed/dotted, vertical lines:
- Category Advisory is shown in white.
- Category Warning is shown in yellow.
- Category Error is shown in red.
- Mouse-Over - Hover with you mouse over such a line and MADRIX RADAR will show a tooltip that includes the timestamp [YYYY/MM/DD HH:MM:SS] as well as the status message.

▪The Y-axis represents the unit of the sensor value [such as °C for temperatures].
