All these endpoints were open actuator/health actuator/info actuator/env actuator/metrics actuator/loggers actuator/threaddump actuator/heapdump actuator/logfile actuator/configprops actuator/beans actuator/mappings actuator/scheduledtasks actuator/caches actuator/conditions

Anyone using Spring, check your exposed actuator endpoints. /actuator/heapdump, /actuator/threaddump, etc. They're very easy to misconfigure, and they often carry extremely sensitive information.

Useful Spring Boot Actuator Endpoints ✅ /actuator/health → Application health status /actuator/metrics → Counters, gauges, timers /actuator/info → Custom project details /actuator/env → Environment properties /actuator/beans → Lists all loaded beans /actuator/loggers → Runtime logging configuration /actuator/threaddump → Thread info for debugging /actuator/httptrace → Recent HTTP requests/responses /actuator/mappings → Shows all request mappings /actuator/prometheus → Metrics for Prometheus exporter

What are some Spring Boot Actuator endpoints useful for performance debugging? Common ones: actuator/metrics - JVM, GC, HTTP request stats. /actuator/heapdump - Heap dump for memory analysis. /actuator/threaddump - Thread dump for deadlocks or slow threads. /actuator/beans - Loaded beans; useful for startup analysis. /actuator/health - Checks app and service health. /actuator/env - See config issues affecting performance.

Common Springboot Interview question for beginners: Q: Your API response time has suddenly doubled. What steps will you take? Expected Thought Process: Check logs → GC, DB, 3rd-party APIs? Look at /actuator/metrics, /heapdump, /threaddump Review recent deployments (code, config, infra)

So we're debugging an async clock deadlock in prod. Leo says get the threaddump if possible. Hard because VisualVM, the tool you need, is a java desktop app. Except, I have #ElectricClojure. How many hours to get a thread dumper utility into prod? That would be zero hours:

Want to debug the ColdFusion Server to improve performance? We have a solution - ThreadDump lets you programmatically clear the logs and improves server performance. Read the blog to know more. Read the blog: adobe.ly/3NO1QAy

New in VisualVM 2.1: Taking thread & heap dumps and controlling Sampler & JFR from the command line! Learn how to use --threaddump, --heapdump, --start-cpu-sampler, --start-memory-sampler, start-jfr and other command line options at visualvm.github.io/docs/comm…

If you found heapdump , threaddump than you can just download it and use strings to look about sensitive information strings heapdumpfile | grep 'api_key' , password etc.
