Debugging tools

This section presents debugging tools available in JMap Admin. These tools help identify JMap Server operating and performance problems.

The tools in this section of JMap Admin are at the experimental stage. Technical support is not offered for them.

Terminal	This tab opens a terminal that allows you to perform tasks using commands.
Worker threads jobs	View active worker threads and pending tasks of the JMap server. A thread is used while updating a data source, caching, calculating statistics, etc.
Layer configuration troubleshooting	This section provides information on the layers of a project, in order to identify the source of a operational JMap application problem. The Layer configuration troubleshooting section provides details of this tool.
JMap Cloud	This section details in tables the files, spatial data sources, projects and tasks that are shared with JMap Cloud. For each resource, data such as name, type, creation date, ID, are displayed.
Resources management	Function used for the development of JMap, used to manage JMap source code translation files.

Layer configuration troubleshooting

This section allows JMap Server administrators to identify the source of an application performance problems caused by layer configuration.

The section displays a table of vector layers on a project. To populate the table, select the project and press Load to display the project layers. By default, layers in the table are sorted in descending order based on the number of map elements in the spatial data source.

You can display the configuration interface of a layer by clicking on its name.

For each layer the table displays the following data:

Name	Name of the layer. An icon indicates whether the layer is visible by default or not on the map. You can sort layers by name. The number in blue indicates the order in which this attribute is considered in the sorting of the layers.
Feature count	Number of map elements from the layer's spatial data source. An icon indicates the element type of the layer (point, line, polygon, text). You can sort the layers according to the number of elements it contains. The number in blue indicates the order in which this attribute is considered in the sorting of the layers.
Visibility thresholds	Visibility thresholds. This section provides the details of this setting.
Request mode	Layer request mode. Three modes are possible: Tile (manual): Load by tile, the administrator has determined the grid. Tile (automatic): Load by tile, JMap Server has calculated the optimal grid. Region: Loading by region. This section provides the details of this setting.
Extent	Layer extent. X and Y parameters indicate the coordinates of the lower left point, in project coordinates. W and H parameters specify the width and height of the layer's extent rectangle, in project mapping units.
Tiling (C x R)	For layers loading by tile, this attribute indicates the number of columns (C) and rows (R) of the grid.
Biggest tile	Indicates the size, in volume, of the largest tile in the layer. This measurement is based on the tiles cache.
Biggest tile (features)	Indicates the size, in number of elements, of the largest tile in the layer. This measurement is based on the tiles cache.
Avg. non empty tile size	Shows the average size (in volume) of tiles that are not empty. This measurement is based on the tiles cache.
Id	Layer Id.

You can select layers in the table and bulk edit the Published, Visible, Selectable and Request mode settings.
