The key to observability in open ecosystems is the ability to collect and integrate metrics, logs, and trace data from components. Fortunately, open source software can help with this. For instance, organizations frequently use OpenTelemetry to instrument microservices, Fluentd for collecting logs, and Prometheus for collecting metrics. Collecting data that supports observability is just one part of ensuring observability in open ecosystems. Organizations also need AIOps to integrate data, provide context, and find meaningful signals across metrics, logs, and traces.
