Analytics
Overview
The Analytics card allows us to see the temporary evolution of received telemetries and analyze the evolution of parameters over a more extended period of time.
If you want to view the exact information from the last telemetry received, check the Telemetry Card.

To graphically represent the values received in the telemetry, we must first establish:
1. Time Period to represent
Time Selection
In the first section of the card, you can configure the time period to analyze. There are two possible modes for this:
-
Relative: allows defining the period from the current moment to the past.
-
Absolute: allows defining a specific period from a pre-determined point A to a pre-determined point B.
In either of the two options above, a value can only be represented if there are telemetries for a defined time period. In any other case, the graph would be empty.
2. Metrics to represent
In this input, select the metric that you want to be represented. You can choose between:
- Temperature (system only)
- System Load (system only)
- RAM
- Disk
- CPU
- Files (solo para procesos)
For more information about each of these metrics, refer to the Telemetry Card article.
3. Available Datasources
Once the time period and metric of interest are defined, the metric's sources must be defined (system and executed processes).
In this case, we can choose several options to be represented jointly in the same graph.
Why doesn't my source selection allow me to choose a source or why is it empty?
If the source selection form doesn't allow selection, it could be due to two reasons:
- It hasn't found the defined metric in the defined time period. No ha encontrado datos para esa métrica en ese periodo temporal.
- There is no application running to allow the procedures to continue.
Once the three values have been selected, the graph should appear as follows:

On the top left of the graph, there are two buttons, one delivers information and the other is an icon for "menu".
This menu allows you to download information represented in the graph in three forms: PNG image, SVG vectorial archive and CSV data.
