GitHub - jvm-profiling-tools/perf-map-agent: A java agent to generate method mappings to use with the linux `perf` tool
The bin directory contains a set of shell scripts to combine common perf / dtrace perations with creating the map file. create-java-perf-map.sh <pid> <options*> takes a PID and options. It knows where to find libraries relative to the bin directory. perf-java-top <pid> <perf-top-options> takes a PID and additional options to pass to perf top. Uses the agent to create a new /tmp/perf-<pid>.map and
The JVM on Fire - Using Flame Graphs to Analyse Performance
Currently there are several tools available to analyse your application performance and show the results. Traditionally these results are either shown in some kind of table form, either flat or as a tree view. Flame graphs are relatively new and take a new angle to show the results. Furthermore, flame graphs can be generated on various levels; tooling hooking into the JVM, but also on (Linux / Mac
How to profile JVM applications | @lightbend
Hi everyone. One of the Tooling team focus lately has been improvement of the contribution process to sbt. Another thing we’ve been thinking is the performance of sbt. Combining these themes together, I’ve been looking into how guys like Jason Zaugg and Johannes Rudolph profile JVM applications, and this post is my findings. The techniques described here should be applicable to both Java and Scala
