Opsian can tell you exactly how your applications are performing in production - right down to the line of code. We do this through our lightweight continuous profiling service for Java and the JVM - our agents collect performance information from across your servers which is then aggregated and made available at line-level granularity via web reporting. We can significantly reduce your production server costs and find performance bottlenecks fast, before they become the sources of down-time and unhappy customers.
