- Profiling is different from Transaction Tracing. Profiling is something you run on demand, for a short period of time, on a specific app/server. It detects application hotspots, just like a typical profiler. Transaction Tracing traces individual transactions, such as HTTP requests, and shows slow parts of each such transaction trace. Once enabled, it traces continuously. Using a profiler and having Transaction Tracing is not exclusive - one can use both.
- The profiler does not require you to enable it in the monitoring agent. It requires no restarts. It works with both embedded and standalone agent.
- SPM client version 1.29.2 or greater is required.
- Anything that runs in the JVM can be profiled - Java, Scala, Clojure, Groovy, JRuby, JPython, etc.
- In order to profile Elasticsearch server enable remote JMX connection (as described standalone monitor setup instructions page) and set SPM_MONITOR_JMX_PARAMS property in monitor config.
