Application metrics

 Problem

When the service portfolio increases due to microservice architecture, it becomes critical to keep a watch on the transactions so that patterns can be monitored and alerts sent when an issue happens. How should we collect metrics to monitor application perfomance?

Solution

A metrics service is required to gather statistics about individual operations. It should aggregate the metrics of an application service, which provides reporting and alerting. There are two models for aggregating metrics:

• Push — the service pushes metrics to the metrics service e.g. NewRelic, AppDynamics
• Pull — the metrics services pulls metrics from the service e.g. Prometheus
