dmpipe --config file [--name name] [--node id] [--sensor id] [--logger name] [--debug] [--verbose]

The dmpipe program reads responses from a process connected via anonymous pipe.

Each request of an observation must contain the process to execute in attribute request. Response values are extracted by group from the raw response using the provided regular expression pattern. A response has to be added for each group in the pattern. The response name must equal the group name.

If any receivers are specified, observations are forwarded to the next receiver via POSIX message queue. The program can act as a sole data logger if output and format are set. If the output path is set to -, observations are printed to stdout.

A configuration file is required to configure the jobs to perform. Each observation must have a valid target id. The database must contain node, sensor, and target of all observations configured.
