Adform, a leading advertising tech platform, transitioned from a fragmented system to a centralized observability system using Grafana to support its growth and manage more than 1,300 data sources for over 25,000 clients. Initially operating in startup mode, Adform’s disjointed tech infrastructure necessitated a move to a more cohesive system, leading to the adoption of Grafana paired with Prometheus. This change allowed Adform's DevOps team to maintain oversight while granting development teams the flexibility to choose their tools, enhancing both control and collaboration. Grafana's organizations functionality enabled separate yet visible monitoring experiences for internal teams, contributing to improved communication and cross-collaboration. The system’s transparency has significantly eased troubleshooting and reduced CPU core usage by 50%. Adform is further expanding its capabilities with successful trials of Grafana Loki and plans to experiment with Grafana Mimir, reinforcing Grafana's central role in its infrastructure.
