I have now installed the Checkfile plugin for the first time, on Github the error was the spelling.
I also installed it on a Linux agent and created a text.txt for a path, which I also entered in the Checkfile.pm for the agent.
In line 44 I have entered the following: # complete below variable w/ any file paths (multiple allowed) 44 my @paths = ('/etc/test/test.txt', '/path/to/test2.txt')
# set below variable to 1 for content retrieval or 0 for presence only
my $getContent = 0; or must the syntax be described differently in Debian/Ubuntu?
In the web application this only remains.
