Monday with JVM logs
[Safepoints] Introduction and safepoints logs
[JIT] JIT logs
[Classloader] Classloader logs - can attaching the JFR (and other profilers) cause the outage?
[GC] Heap after GC - do I have a memory leak?
[GC] Allocation rate
[GC][G1GC] Heap before GC - is my heap wasted?
[GC][G1GC] G1GC Stop-the-world phases
[GC][G1GC] Efficiency of the old generation cleanup
My articles about JVM performance and tuning
Biased lock disabled, again
To tune or not to tune? G1GC vs humongous allocation
JVM internals basics - Stop-the-world phase (safepoints) - how it works?
Time to safepoint - finally there is a tool to find long ones, and yes it is the async-profiler
Can G1GC cause outage?
From one JDK bug to another?
How can inefficient algorithm degrade performance with innocent G1GC in the middle? Humongous object strikes back
Spring Boot + Spring Security + Apereo CAS + Concurrent Session Control = Heap memory leak
Spring Session JDBC + Apereo CAS = Heap memory leak, and it is a documented feature
Full GC every hour after deploying new application version
Continuous profiling with async-profiler
Continuous profiling with async-profiler - long time to safepoint - logs vs swap
Spring Boot + good old JSP/Tags = disaster
The ultimate monitoring of the JVM application - out of the box
My open source projects
I created some tools that help me with profiling big application with Async-profiler:
JVM/GC logs analyzer
Here is my open source JVM and GC logs analyzer:
