Paytm Insider, a popular platform for purchasing event tickets in India, faced challenges with its logging and monitoring systems as it scaled, experiencing high costs and inefficiencies during traffic spikes. To address these issues, the DevOps team implemented Loki, a centralized solution integrated with Grafana and Prometheus, which streamlined their logging processes and significantly reduced costs by 75%. The solution allowed for efficient log management and faster debugging, decreasing the average response time for latency issues from 30 minutes to 10 minutes and centralizing alerts, which improved correlation between infrastructure and application performance. The team plans to further optimize costs and functionality, and since deploying Loki, they have experienced stable, uninterrupted service even during heavy traffic events.
