Snail

Snail is a QGIS plugin allowing to monitor performances:

• CPU and RAM monitoring with or without a dedicated graphic
• RAM warning when a specified amount is exceeded

More functionalities will come in time.

Installation

Python dependencies

Once you have installed Snail with the Plugin Manager tool in QGIS, a last step is necessary to have a fully operational plugin. Indeed, some Python modules are necessary and have to be installed.

Of course, the dependency may be installed manually with pip, apt-get, pacman or others, but Snail provides an embedded solution too. Actually, if a package is missing, then the next window will be opened:

If you click on Yes, the pip install -user command will be runned to install lacking dependencies. It has been tested on Windows and Archlinux. Once dependencies have been installed, you have to restart QGIS to use Snail.

Qt5 QML charts module

On Windows, no additional installation steps are required. However, on GNU/Linux platforms, you may need to install some more packages necessary for drawing QML charts. For example:

• Archlinux: qt5-charts
• Debian: python3-pyqt5.qtquick

Settings

You can open a settings window through the Snail menu. It allows you to customize some colors as well as defining an amount of RAM above which a warning message is displayed periodically.
