I have downloaded the 7.15 version on logstash and unzipped. Unfortunately the lack of an installer leaves the solution in a non working state. My current - first - challenge is getting logstash to use the bundled jdk. I cannot change the java that is being used as that is required by other components, so need to set up logstash to run its own jdk. (Hopefully it runs a jre in production?) ---

> [@tractor\_boy](#): > > so need to set up logstash to run its own jdk. (Hopefully it runs a jre in production?) logstash comes bundled with a JDK, not a JRE. I have no idea why they would do that. logstash will use the bundled JDK unless JAVA\_HOME is set in the environment. So you can `set JAVA_HOME=` before running logstash.bat ---
