Part 3 of 4 · My Software Journey

Mission 2#

  • Discover Prometheus and Grafana

    • I discovered Prometheus, understanding its functionality and how to use it for monitoring applications. Additionally, I learned about Grafana and how to visualize the metrics collected by Prometheus.
    • I also gained knowledge on creating and using an Exporter to gather metrics from an application and expose them to Prometheus.

  • Collect and Visualize Asterisk Metrics

    • I collected metrics from an Asterisk server using the Asterisk res_prometheus module and exposed them to Prometheus.

    • I visualized these metrics using a simple Grafana dashboard.

    • Additionally, I used node_exporter to collect metrics from the Asterisk server node.
