===========
Process Log
===========

The Process Log shows messages related to process execution, which actually happens in the cloud server.


This popup window will open automatically when certain tasks are executed, and it can also be opened at any time by clicking on the "Process Log" button in the top bar:

.. image:: ./images/processLogBtn.jpg 
    :align: center
    :width: 40%

The log popup initially opens in a minimized state showing only the last message, but it can be expanded by using the left top icon:

.. image:: ./images/processLogMin.jpg 
    :align: center
    :width: 50%

Which results in:

.. image:: ./images/processLogMax.jpg 
    :align: center
    :width: 50%

The log window can be minimized again or closed.

Estimating the **duration of a process** in Pathfinder is nearly impossible because of the many factors involved, including how many other processes there are, but the Process Log shows the time it's taking for each process to complete, so the users have an approximate estimation of how long it will take to run it again in similar conditions.

Data Preparation Processes
==========================

These processes are run automatically by the application:

* When a *project* is created, a process is executed to prepare the *Digital Elevation Model (DEM)*, *Slope Map* and other information relative to the project area.

|

* When a *layer* is added to the project from a base dataset, or its ring/buffer options are changed, a process is executed to *clip and buffer* the data and prepare it for display and analysis.

   :align: center
   :width: 50%

.. note::
   *It will not be possible to add layers to the project until its post project creation process ends*.

Stop a Process
==============

In some cases, a process can be running much longer than expected, or we wish to stop it in order to change some parameters and run it again. The Process Log shows a "Stop" button we can use to cancel the process.

.. image:: ./images/processStop.jpg
   :align: center
   :width: 60%

After the process stops it will be displayed as "Failure", but without the red color indicating a problem, and it can be executed again.

.. image:: ./images/processStopped.jpg
   :align: center
   :width: 60%

.. note::
   *It is not advisable to stop the project post-creation process calculating the terrain variables. If this process is canceled, it becomes impossible to add layers to the project and we will need to recreate it*.
