We are trying to catch a memory leak, and we are using with jemalloc. How do you change the tree to display symbol/class names? Right now, our gif looks like this: enter image description here

On most tutorials I see, they just say to set the following 2 env vars:

 echo $LD_PRELOAD
/usr/lib/x86_64-linux-gnu/libjemalloc.so

 echo $MALLOC_CONF
prof:true,lg_prof_interval:29,lg_prof_sample:17

The command I'm running is: jeprof --show_bytes --gif which java jeprof*.heap > mem.gif

We are running a java application from a docker-compose file, using the image: openjdk:13-jdk-alpine

    you should check async-profiler, I bet it does a lot more for you – Eugene Jul 26 '21 at 18:02
  • I will check it out if jemalloc cannot give me information I need – Ethan Solomon Jul 26 '21 at 18:04
  • What does this have to do with Java? – boneill Jul 26 '21 at 18:30
  • I'm running a java application...? – Ethan Solomon Jul 26 '21 at 18:38
  • Tracking memory leaks in a Java application doesn't involve looking at the usage of jemalloc, unless you're debugging the JVM itself, in which case you need advice that you're not likely to find on SO. When you're asking for class names, do you mean Java class names? If so, you need use a Java memory profiler, not a jemalloc tool. – boneill Jul 26 '21 at 18:45
  • Yes, im trying to see if there is a leak in native memory. I dont literally mean class names, i mean such as the image at the bottom of this article. https://technology.blog.gov.uk/2015/12/11/using-jemalloc-to-get-to-the-bottom-of-a-memory-leak/. it provides readable content, not memory addresses – Ethan Solomon Jul 26 '21 at 19:14
