Unable to load the base.rb file in my plugin

Elastic Stack Logstash
1

Hello,

Whenever I attempt to run logstash using the --configtest flag this is the message I keep getting:

The error reported is: 
Couldn't find any codec plugin named 'transit'. Are you sure this is correct?
Trying to load the transit codec plugin resulted in this error: no such file to load -- logstash/lib/logstash/codecs/base

any ideas..?

It sounds like you've got require "logstash/lib/logstash/codecs/base" in your plugin. I don't think this is right, it should probably be require "logstash/codecs/base" (remove the leading logstash/lib part)

Thanks!

However, now when I run logstash using:

/opt/logstash/bin/logstash agent --verbose --log /opt/logstash/log/logstash.logs --config /opt/logstash.conf --pluginpath /opt/logstash/lib/ --debug

This is the output that I receive:

Sending logstash logs to /opt/logstash/log/logstash.logs.

Any ideas?

Try using the --debug flag which should show you a stack trace. Without more information, I'm not sure what is going on.

I get the same Error message when I run both --configtest and --debug

This is the new output I get when I run:

/opt/logstash/bin/logstash agent --verbose --log /opt/logstash/log/logstash.logs --config /opt/logstash.conf --pluginpath /opt/logstash/lib

Output:

I am following the instructions located here: Contributing to Logstash | Logstash Reference [8.11] | Elastic, the only difference is that I am implementing a codec.

So far, I have tried to place the transit.rb file in 2 locations:
(FYI.: logstash is installed at: /opt/logstash)

  1. /opt/logstash/codecs (I manually created the codecs directory there)
  2. /opt/logstash/lib/logstash/codecs (there is a list of codecs located here)

When I run these 2 commands, respectively (depending on where I chose to place the transit.rb based on the options above)

  1. /opt/logstash/bin/logstash agent --verbose --log /opt/logstash/log/logstash.logs --config /opt/logstash.conf --pluginpath /opt/logstash/codecs
  2. /opt/logstash/bin/logstash agent --verbose --log /opt/logstash/log/logstash.logs --config /opt/logstash.conf --pluginpath /opt/logstash/codecs

I get the same error...however, the 2nd option seems to work a lot better than the first.

Can you post the code for your plugin?
