Ricardo Liberato shares his experience in using Grafana, Prometheus, and Grafana Loki to monitor high cardinality jobs at a Fortune 100 life sciences company, highlighting the synergies between these tools for effective observability. By integrating Loki with Prometheus, the team was able to monitor job-run performance beyond infrastructure, enabling them to reduce load cycle times significantly and achieve 40% savings on cloud infrastructure costs. The implementation involved custom-built exporters and dashboards that aggregate data from various enterprise systems, providing insights into compute and memory efficiency and allowing for better resource allocation. This setup not only improved operational control but also provided feedback to development teams to enhance production performance. The combination of metrics and log information facilitated a deeper understanding of job performance and resource usage, leading to further cost optimizations through predictive scaling of resources.
