Messaging Monitor

## Description

scmm is the messaging monitor, the graphical interface to scm. It allows to view the messages from all modules sent around by the SeisComP messaging system. Therefore, scmm can be used to debug configured message groups and module connections, e.g. in a system with several processing pipelines and specific message groups.

In addition, scmm allows to view the content of single messges as well as the memory consumption and other statistics of all modules connected to the SeisComP messaging system.

View message notifications.

View the message content by clicking on individual messages.

View module memory consumptions.

View module statistics.
