If you set this to true, you normally do not set the availability regex settings in order to allow availability to be determined based solely on the successful execution, regardless of the exit code or output. If this is false, setting one of the avail regex settings will override it as if it were true."/>

Expression is evaluated by Pattern.find() so match actually means first match found in text. Pattern `OK` matches multiline text `Service status\n is OK`. By default ^$ represent start/end of output text. To match start/end of line add (?m). eg. `(?m)^ is OK$`. To match whole multi-line output use (?s), eg. `(?s)Service.*OK`."/>

For each measurement that should be collected for resources of this type, a metric element is added.
In addition to identifying the metric, a default collection interval and whether or not the
metric is even collected by default are indicated. If the resource has no measurements to be
collected, these elements may be omitted. Note that the metric property string contains information
like the arguments to pass to the executable and an optional regex to use to pick out the metric
value from the output of the executable. The arguments are specified inside curly braces. If the metric
value is the entire output, you do not have to specify a regex, the output will be assumed to be
the value of the metric in that case. If regex is explicitly the string "exitcode", the metric value will be
the CLI executable's exitcode value.
