Problems using spaces in command name

[weberdigital]

Current Behavior

When you use a grafana graph for an service consists a command name with spaces, the graph won't be rendered.

Possible Solution

rawurlencode the value $this->object->check_command for the png url.
E.g. in modules/grafana/application/controllers/ImgController.php, line 316
