is there any way to put a relative path in the conf files?

is there any way to put a relative path in the conf files?



Well, I've been the following problem .
I've got my workspace the following way


bin conf example lib LICENSE locales patterns README.md spec vendor



In the conf folder I've got the file logstash-apache.conf with the next input


logstash-apache.conf


input
file
path => "./../example/logs/logprueba/*_log"
start_position => beginning

}



When I run logstash, I get the message:



File paths must be absolute, relative path specified: ./../example/logs/logprueba/*_log


File paths must be absolute, relative path specified: ./../example/logs/logprueba/*_log



Is there any way to put a relative path?






it's not really a relative path, but since recent logstash includes support for environment variable expansion in the conf file (may need to pass --allow-env depending on version) if you're willing to always run logstash from a particular directory (the one with the conf file in it, for instance), you could use path => "$PWD/../example/logs/logprueba/*_log". Alternatively, if you're willing to set a var, path => "$LOGS_DIR/*_log"

The answer is no -- not without modifying the logstash source code... According to the docs:



The path(s) to the file(s) to use as an input. You can use globs here, such as /var/log/*.log Paths must be absolute and cannot be relative.



You can always use the environment variables using bash $(pwd) to yield the current destination, this could not be the master solution for you but at least is not anti-pattern:


$(pwd)



export CSV_FILE=$(pwd)/temporal_datasets/dataset.csv


export CSV_FILE=$(pwd)/temporal_datasets/dataset.csv



then in the logstash config file


input
file
path => '$CSV_FILE'
start_position => "beginning"
sincedb_path => "/dev/null"
ignore_older => 0
