5.6.2 The “Data Log Viewer” or “Historian”
Data is logged and buffered locally in the DTS IoT Gateway. This enables logged history of up to 30 days to
be viewed and graphed locally on the DTS IoT Gateway. If the DTS IoT Gateway is registered to the cloud,
this buffering will prevent logged data loss if the Internet connection to the cloud is lost.
To view the logged data on the DTS IoT Gateway itself:
Click on “Data Log View” on the side menu.
Press the “Settings” button.
A popup list will appear showing all the available data points from all the attached devices.
Select one or more data points that you would like to plot
Press the “Submit” button at the bottom of the list.
The DTS IoT Gateway will then show a separate plot for each data point selected.
Each plot consists of two parts:
a) The small timeline below shows a thumbnail of the data for the past 30 days. The two window
handles (show by the red arrows) can be dragged to select the time period of interest.
b) The main plot above shows the logged detail. Hovering over a particular part of the plot will
show the date/time and the value on the plot at that position. This position is shown by a vertical
grey line, and a blue dot on the plot curve.
The above assumes that the DTS IoT Gateway has been running for sufficient time to allow logged data to
accumulate. Logged history of up to 30 days may be viewed.
