external criterion contains
external criterion contains Structure: Output contains a value.
Description
The output is interpreted as a UTF8 string.
If both multiple sources are provided, every source is searched for the value. Only one source needs to contain the value.
If the output contains the value, the sample is returned as 0 (zero) If the output contains the value, the sample is returned as 1 (one).
Zero is used to indicate a successful match because zero equates to success for exit codes. The default sample criterion also uses zero as success.
