Filters and Masks

List Formation

When you create various objects in Wialon (geofences, places, drivers, custom fields, etc.), they are organized into lists. Items on the list are displayed in the alphabetical order: numbers first, then Latin alphabet, and Cyrillic at the end. When a new item is created, it is added primarily to the end of the list, but when you open this list again, all items are arranged in the alphabetical order. After renaming an item, it remains at its former place until you reopen the list.

Dynamic Filter

If a list contains a great number of items, it can be not so easy to quickly find necessary item. For your convenience, you can fulfill dynamic search. It is available in all panels except Tracks. Simply start typing the name of an item (geofence, unit, route, etc. depending on the panel opened). You can start typing a name from any point. While typing, items which correspond to your query will be immediately displayed.

If you leave the search field empty, all items will be displayed.

The dynamic filter can be found also in properties dialog of units, units groups and users when adjusting access right. However, the difference is that search results are displayed not while typing but after you press the Apply button.

The particularities of the dynamic filter usage in the Monitoring panel are described in Unit List Management section.

While typing you query, you can use wildcard symbols such as * and ? which use is described below.

Name Mask

Besides the dynamic search, there is the other type of filter. It is used to specify an item (sensor, geofence, etc.) when configuring reports, notifications, etc. This assumes that you can define item's name using the wildcard symbols asterisk * and/or question ?

The asterisk sign is a wildcard symbol which represents any combination of allowed characters in the name of an item. It can be placed in any place of the query (at the beginning, in the middle, at the end) or in several places at once, depending on which part of the name is known or is the same for a number of items. For example, if you type *h*nda*, all Hondas and Hyundais will be found.

Another wildcard symbol which can be used is the question sigh (?). It replaces any single character (only one character). As well as the asterisk sign, it can be put at any place of the query.

The request is not case sensitive.

For example, a unit has two fuel sensors with the names Sensor fuel level and Fuel in tank. We are going to create a notification which would be based on both of them. To achieve it, in notification properties we must set sensor name mask in such a way that it would correspond to the names of both sensors. In our case the best choice is *fuel*:

You can do a search without using the asterisk but then you have to indicate the name (geofence, driver, sensor, etc.) exactly as it exists in the system.

To find all items of some kind (users, sensors, geofences, etc.), simply type one asterisk in the input box of search terms.

Masks are employed:

  • in notifications to specify sensor, route or driver under control as well as set SMS text mask or parameter in messages;
  • in user properties to set host mask for users;
  • in unit log to quickly find the necessary row;
  • in reports to specify driver, sensor, event/violation, route and its geofence, and when selecting geofences;

In all panels masks can be used instead of the Dynamic Filter.
