You can optionaly configure the warning and critical limits. By default warning
|
||||
is set to 1 and critical is not set at all. You can set the limits either for
|
||||
the entire plugin or per individual metric. The individual values take
|
||||
precedence over the general ones. See the following example:
|
||||
the entire plugin or per individual metric and down to a specific device. The

more specific values take precedence over the general ones.
