Thread Dump

Resources:

• https://www.baeldung.com/java-analyze-thread-dumps
• https://blog.dbi-services.com/weblogic-server-process-takes-100-cpu/

Possible solution:

• jstack can generate thread dump file with all needed information about thread usage, for complex projects is better to use some analysing online tools

• weblogic also has thread dump monitoring, but it is worth to have some other tool to decrypt these complex information thread dump info into better form eg. graph, etc.

Check JVM heap size or Thread dump

environment >> servers >> your server >> monitoring >> performance >> info about heap
