How to parse multiple log files using logstash?

Question

I have a few log files like below data_log_01.log data_log_02.log data_log_03.log data_log_04.log

Is there any way that I can parse these logs one by one using a single config file in logstash?

Answer 1

How about using the file input plugin with a wildcard?

An exmaple configuration could look like this, assuming your log files are located /home/of/your/logs/:

input {
    file {
        path => [
            "/home/of/your/logs/*.log"
            ]
        }
    }
}

The path value has to be an absolute path! You might want to see the docs on using path.
