Logging, Traces, and Metrics: What is the difference?
Metrics tell you what broke, logs tell you why, traces tell you where. A practical guide to the three pillars of observability, with real incident examples and OpenTelemetry.
Metrics
Optimize Java Application Performance by Monitoring JVM Metrics
One Java application can generate up to hundreds of metrics. There are a few crucial indicators for monitoring that you should pay attention to thread counts, garbage collection, and memory usage. These metrics are accessible via JMX.
OpenTelemetry vs OpenTracing - Key Differences and Migration Path
OpenTelemetry and OpenTracing are open-source projects to enhance observability in distributed systems, but they serve distinct purposes. Take a look at their key differences and how to migrate from OpenTracing to OpenTelemetry.
