Get logstash version

Question

How does one get the version of Logstash?

root@elk:/usr/share/elasticsearch# bin/logstash --help
bash: bin/logstash: No such file or directory

I have Logstash running on my system. Also.

root@elk:/# logstash -V
bash: logstash: command not found

Also.

root@elk:/# ps aux | grep logstash
logstash  1725 45.3  8.5 1942860 175936 ?

Logstash is one of those things that just doesn't quite live where you expect it to live, and the documentation is reallllly light (read: non-existent) on where they expect you to find things, so if you've installed it from a package then it can be nigh impossible to find the expected location documented. ¹

Logstash typically lives in /opt/logstash and you can find the logstash binary in the bin folder (/opt/logstash/bin).

From there you can run -V or --version

./logstash -v

or

./logstash --version

From your comments on another answer, it would appear that this is in a docker container. This is the sort of thing you should really be including in your original question.

You will want to make use of docker exec. You will need to use docker ps to list your containers, and pass that through to your docker exec command.

For example:

docker exec -d elk_container /opt/logstash/bin/logstash --version

_{¹I don't want this to be misconstrued. Logstash documentation is excellent - it's just the parts about where all the different bits are expected to live that's impossible to find}

On Logstash 5.x on CentOS/Red Hat:

Location of logstash binary: /usr/share/logstash/bin/

Then this will tell you the version: ./logstash -V

Try find / -type f -name "logstash" 2>/dev/null to find logstash, it will take some time to return though.

Then with the location of logstash that you find, run the binary with the --version flag.

My logstash on Linux 17.04, logstash was found at: /usr/share/logstash. However, the config files are found at /etc/logstash. I had to copy over the config files to the new location: /usr/share/logstash/config to get logstash to work.

From the documentation:

-V, --version Display the version of Logstash.

(which took me all of about 30 seconds to find, by the way)

Firstly, you'll need to find the path to logstash. Try searching for it by running updatedb && locate logstash/bin. I found mine in /usr/share/logstash/bin.

Running logstash with the "-v" or "--version" flags should return the version.

Logstash keeps its version identity in a ruby file i.e version.rb In Ubuntu, you can find version file at following location. So,use this cat /opt/logstash/lib/logstash/version.rb
