Metrics and Monitoring

The ESB3027 AgileTV CDN Manager includes a built-in metrics and monitoring solution based on Telegraf, Prometheus, and Grafana. A set of default Grafana dashboards provides visibility into CDN performance, displaying host metrics such as CPU, memory, network, and disk utilization—collected from the Director and Cache nodes via Telegraf—as well as streaming metrics from each Director instance. These metrics are stored in a Time-Series Database and visualized through Grafana dashboards. Additionally, the system supports custom dashboards using Prometheus as a data source, offering flexibility for customers to monitor all aspects of the CDN according to their specific needs.

Accessing Grafana

To access Grafana, point a browser towards any node in the cluster on port 3000. e.g. http://manager.local:3000/ and log in using the default administrator account credentials listed below.

Known Limitation: Grafana does not currently support Single-Sign-On (SSO) using Zitadel accounts.

Username: admin
Password: edgeware

On the left column, click Dashboards and select the Dashboard you wish to view.

Custom Dashboards

The grafana instance uses persistent storage within the cluster for data storage. Any custom dashboards or modifications to existing dashboards will be saved in the persistent storage volume, and will persist across software upgrades.

Billing and Licensing

A separate VictoriaMetrics Time-Series Database is included within the metrics component of the manager. It periodically scrapes usage data from Prometheus to calculate aggregated statistics and verify license compliance. This data is retained for at least one year. Grafana can also use this database as a source to display long-term usage metrics.
