2) Web: Dashboard

The objective of the dashboard is to support the decision making and maintenance interventions, giving a general view of the condition of the spots, based on previous measurements and limits (A1 & A2) defined by the user.

The Dashboard consists of the following columns:

• Status: shows the current status of the spot, informing if it has exceeded the alert limits A1 and A2, defined in the registration of the point. The status is updated with each collection made by the application or Gateway;

• Machine: name of the machine to which the spot is registered;

• Spot: name of the monitoring point;

• Trend: Analyzes the variation of the spot over time. Each circle represents the worst alert level (A1 and A2) exceeded for each of the last seven days preceding the last collection date. Further information is given by hovering over the circles, such as the date, the violated alert and the estimated time that the spot was alerted;

• Average Velocity: average value of the RMS velocity on the day of the last collection. The arrow next to the value indicates the change from the day before the last collection;

• Average Temperature: average temperature value, in °C, on the day of the last collection. The arrow next to the value indicates the change from the day before the last collection;

• Average Acceleration: average value of RMS acceleration on the day of the last collection. The arrow next to the value indicates the change from the day before the last collection;

• X, Y and Z Spectrum: comparison between the latest spot spectrum performed for each axis. Hovering over the arrow/symbol displays the energy value of the last five spectra, as well as the energy of the reference spectrum. The direction of the arrow indicates whether the value has increased,
decreased or remained constant relative to the reference spectrum.

Column LF shows the trend of low frequency energy variation (≤300 Hz), while column HF shows the trend of high frequency energy variation (>300 Hz), always in relation to the reference spectrum;

• BAT: estimated remaining battery life of the Dynalogger associated with the spot;

• MEM: indicates the remaining storage capacity of the DynaLogger memory. The duration of the memory depends on the sample interval, i.e. how often the DynaLogger collects and stores data. This interval can be consulted by hovering over the memory card icon for the desired spot. They are divided into 4 colors:

1. Green: more than 40% free memory; 
2. Yellow: between 20% and 40% free memory; 
3. Red: less than 20% free memory;
4. Grey: Memory full. When the memory is full, the DynaLogger stops collecting data, keeping the data already stored.

Note: Whenever data is collected from a DynaLogger, by the app or by the Gateway, the internal memory of the device is erased.

• Last Sync: shows the date of the last synchronization, i.e. the date of the last measurement point collected for this spot.

In addition, at the top of the page there is a search bar which enables the user to search for a specific machine, spot or serial number of a DynaLogger.
