I am learning something about ElasticSearch Stack and I am having a problem installing Logstash on Windows 10 (windows 10 enterprise N OS build 15063.674).

I installed ElasticSearch and Kibana and these are up and running.

I followed the steps on this page to install Logstash:

Step 1: Download and unzip Logstash downloaded "logstash-5.6.3.zip" file and unzipped it to: "c:\program files\elastic\"

Step 2: Prepare a logstash.conf config file as described here, I created a "logstash-simple.conf" in the "c:\program files\elastic\logstash-5.6.3>" folder

Step 3: Run bin/logstash -f logstash.conf at this point I am having the issue (I tried using both cmd and PowerShell with elevated privileges): the result is:

The system cannot find the path specified.
"could not find jruby in C:\Program Files\Elastic\logstash-5.6.3\vendor\jruby"

Of course, the "vendor" folder exists, and there is a "jruby.bat" file inside. I searched the web and I found something about the JRUBY_BIN environment variable but event after the creation (and the additional reboot) the issue still is there.

Can someone address me to the problem?

  • Have you tried running the `setup.bat` file before? – baudsp Nov 03 '17 at 15:29
  • yes, I tried, the message is the same: `PS C:\Program Files\Elastic\logstash-5.6.3> bin/setup.bat The system cannot find the path specified. "could not find jruby in C:\Program Files\Elastic\logstash-5.6.3\vendor\jruby"` – dancerjude Nov 03 '17 at 15:39

    I reproduced the problem on my machine (same windows version, same logstash release, same install folder). The problem is the installation directory, perhaps the space in the path. I successfully logstash after moving the logstash folder in a path without space (`C:\Users\me\Downloads\logstash-5.6.3\ `) – baudsp Nov 03 '17 at 15:50
  • you are right @baudsp thank you... moving from "program files" to "my" folder the jruby problem disappeared :-) – dancerjude Nov 03 '17 at 17:51
  • anyway, another problem happened :-( `Error occurred during initialization of VM Could not reserve enough space for object heap` – dancerjude Nov 03 '17 at 17:52

    According to https://stackoverflow.com/questions/4401396/could-not-reserve-enough-space-for-object-heap, it seems it's a memory problem. I think the solution would be to set the option `-Xmx512m` in the file `logstash-5.6.3\config\jvm.options` – baudsp Nov 06 '17 at 08:38

I have found this solution: https://discuss.elastic.co/t/logstash-does-not-start-says-could-not-find-jruby-in/113500. You can also try move logstash folder out of program files direct to C, it might help.
