Evan Mouzakitis concludes a three-part series on monitoring Google Compute Engine (GCE) by detailing how Datadog can enhance the monitoring capabilities beyond Google's native tools. While the previous parts discussed key metrics and their collection via Stackdriver Monitoring API and gcloud, this final part highlights Datadog's ability to provide comprehensive visualization, alerting, and correlation of GCE metrics with other infrastructure components. Datadog retains data at full granularity for 15 months, facilitating long-term trend analysis, and can integrate with over 850 technologies and services through its Agent. Users can quickly start monitoring by enabling the Google Cloud Platform integration or installing the Datadog Agent, which offers additional system resource metrics. Datadog's customizable dashboards and advanced tagging and alerting features enable detailed monitoring and proactive issue detection, providing greater observability into GCE operations.
