I am using logstash 2.4.1 version and went through the readme here [https://github.com/magnusbaeck/logstash-filter-verifier](https://github.com/magnusbaeck/logstash-filter-verifier) Created test.json according to my requirement for application request. Since, I have custom location of logstash, logstash-filter-verifier is unable to find the installation. Can you guide with any args or way to get it recognized to continue my testcase testing? ---

Run LFV with `--help` to get the complete list of options. In there you'll find the `--logstash-path` option that you'll be able to use in this case. ---
