You can define the details of alerts.

The entrances of defining alert:

The Define Alert Dialog:

With the above alert definition, the “mtu” data unit shown on the map will be highlighted if the specified condition matched:

▪Provide different variable analysis operations according to different variable types.

▪Optimize the definition of condition in the ‘If’ statement to make it closer to natural language and easier to understand.

▪Support more methods for different types of variables in ‘Operation’ and expand the range of cases covered by alert.

The list of operations supported by the three types of string, number, and bool are as follows:
