MATRIXX Monitoring and Logging
- About MATRIXX Monitoring and Logging
  MATRIXX Monitoring and Logging provides the tasks required to monitor the various MATRIXX Digital Commerce components. It identifies where information is logged and provides recommendations on what you should monitor regularly.
- Monitoring MATRIXX Business API Gateway
  The MATRIXX Business API Gateway SNMP statistics are defined in the matrixx_web_mib.txt file and you display them using the snmp-net-utils snmpwalk command.
- Monitoring MATRIXX Call Control Framework
  The topics in this section provide information about monitoring Call Control Framework (CCF) components, including Network Enabler and Camel Gateway.
- Monitoring Diameter Events
  Diameter Event Logger listens to the Diameter Gateway through a TCP connection and logs diameter Rx messages to a JSON file.
  - Manage Diameter Event Logger
    This procedure describes how to start and stop Diameter Event Logger.
  - Configuring Diameter Event Logger
    You can configure Diameter Event Logger listening port, output directory, and log file rollover time.
  - Change Diameter Event Logger Log level
    You can set the Diameter Event Logger log level to debug any issues.
- Monitoring MATRIXX Engines
  Use SNMP to monitor a MATRIXX Digital Commerce environment to confirm that the MATRIXX Engines are functioning properly in an active-standby HA configuration and that during an engine failover, the switch-over operation is working as designed. MATRIXX Digital Commerce also offers statistics for other components that indicate those components are running correctly, and to help you diagnose problems.
- Monitoring Event Repository
  Enable and configure the Event Loader purge task for an Event Repository by answering the event purge expired events-related questions when running the create_config.py script.
- Monitoring MATRIXX Gateways
  You monitor the MATRIXX Gateways using JMX.
- Monitoring Event Streaming
  Event streaming errors are logged in the Event Streaming Framework mtx_event_streamer.log file. Event Streaming Framework uses Log4j 2.x to log error, debugging, and informational messages
- Monitoring a Cloud Native MATRIXX Deployment
  You use the Prometheus and Grafana third-party products to monitor a cloud native MATRIXX Digital Commerce deployment.
- Monitoring MATRIXX Route Cache
  You monitor the Route Cache by reading watermark log messages for each Route Cache table, and by monitoring the Route Cache SNMP statistics. The SNMP statistics are defined in the matrixx_rc_mib.txt MIB file and are returned by the print_snmp_stats.py script. They include statistics on subscriber and session data, including statistics on insert, fetch, erase, and iterator operations, general statistics on subscriber records, and garbage collection.
- Monitoring MATRIXX SBA Gateway
  The MATRIXX SBA Gateway SNMP statistics are defined in the matrixx_web_mib.txt file and you display them using the snmp-net-utils snmpwalk command.
- Monitoring Payment Service Logging
  Payment service logs messages to the payment-service.log.
- Monitoring MATRIXX SNMP Statistics
  By default, the SNMP Agent running on a MATRIXX Engine monitors the status and health of all the blades and clusters it contains. It collects statistics to aid in identifying potential processing problems.
- Monitoring MATRIXX Traffic Routing Agent
  Traffic Routing Agent SNMP statistics are defined in the matrixx_tra_mib.txt MIB file and are returned by the print_snmp_stats.py script when run on any of the Traffic Routing Agent servers. They include categories such as TCP traffic, UDP traffic, Diameter Gateway traffic, and MDC Gateway traffic.
- Monitoring MATRIXX Web Apps
  You use the MATRIXX Digital Commerce system logs and SNMP statistics and notifications to monitor the MATRIXX Digital Commerce web-facing applications, such as RS Gateway, Gateway Proxy, and My MATRIXX.

Monitoring Diameter Events

Diameter Event Logger listens to the Diameter Gateway through a TCP connection and logs diameter Rx messages to a JSON file.

For information about installing Diameter Event Logger, see Installation and Configuration.

The Diameter Gateway uses a persistent connection to Diameter Event Logger. If the connection is lost, the Diameter Gateway attempts to reconnect. It is possible that some events will not be logged if the connection is intermittent.

During MATRIXX Engine configuration, you must answer the following create_config.info question to enable Diameter Event Logger: If using the Diameter Gateway external log service, what is its address (host:port)?

This configuration is per-blade. For information about the configuration parameters, see the discussion about configuring Diameter Event Logger.

Diameter Event Logger is packaged with the latest MATRIXX Engine system MDC definitions. It automatically loads any custom MDC definitions in /opt/mtx/conf/mdc_config_custom.xml when you start it.

Diameter Event Logger logs its status messages to /var/log/mtx/diameter-event-logger.log.
