External tests are active if the pickupdir option is set.
Programs to be run are listed one per line under the [ext] heading
or in the ext.cfg file. They are run after all other tests by the
Mr Big main loop.
The command should produce a file which is placed into the pickup
directory. The name of the file determines the test name, i.e.
the name of the column in the display. The first line in the file
should be a single word indicating the status: green, yellow or
red. The file name as well as the status is case sensitive.
To perform tests on behalf of other machines, specify the file name
as:
machine,example,com.test
After all commands are run, files in the pickup directory are examined
and reports sent to the display. The files are removed.
It is not necessary to use Mr Big to generate the files. They
can be produced by another scheduling mechanism, uploading
files from another system etc.
