Events Monitoring

Overview

On top of our logging and metrics, Magma has a metrics monitoring system. Events capture rich, searchable data pertaining to the gateways, and entities tracked by the gateways. Events are a work in progress, but has been designed to track the following:

• S1AP message tracing
• Subscriber session tracing
• Subscriber data usage, bearer creation
• Gateway connection status
• eNodeB tracing
• New gateway configurations pushed

If Fluentd, Fluent Bit, and Elasticsearch have been correctly configured on your setup, events should automatically be available.

Viewing Events

We recommend two primary ways to view or query for events: either through our NMS UI, or through our REST API.

NMS

The easiest way to view Magma's events is through the NMS UI. Events can be seen on the main network dashboard. Gateway and subscriber specific events tables are also provided.

REST API

We provide a REST API for querying events. The Magma NMS itself uses this API to provide its interface. We use OpenAPI, so more details can be found in our various Swagger files.

• swagger.yml
• swagger.v1.yml

Currently we provide three GET endpoints for our REST API:

/events/{network_id}:
/events/{network_id}/{stream_name}:
/events/{network_id}/about/count:

Event Streams

Events are divided into the following streams, that can be filtered on either the NMS or the REST API

(This may not be an exhaustive list)

• magmad: Events related to general access gateway function
• health Events related to federation gateway health
• sessions: Events related to subscriber sessions
• mme Events related to MME function, S1 issues, and subscriber attach/detach

Available Events

Events are defined in swagger yaml files. This list may not be exhaustive.
