Configuring Diameter Event Logger

Diameter Event Logger loads default configuration parameter values from the classpath. You can configure Diameter Event Logger listening port, output directory, and log file rollover time.

To override the default values, use a configuration source to load a custom diameter-event-logger-config.yaml file to /opt/mtx/conf. When starting Diameter Event Logger and the custom configuration file is loaded successfully, a message is logged to indicate which file is loaded. For example:
[main] INFO c.m.standalone.eventlogger.Main - Reading application config file from diameter-event-logger-config.yaml
Configuration Parameters lists the Diameter Event Logger configuration parameters.
Table 1. Configuration Parameters
Parameter Description Default Value

mdc.port The port on which the Diameter Event Logger listens for events from the Diameter Gateway. 17030
json.output.directory The directory to which the Diameter Event Logger writes the JSON log files. /opt/mtx/data
