Is there any way to to put some messages on running logstash

(Chitresh Gargwanshi) #1

Hii all,
I recently started to learn logstash, I have created a simple configuration file as shown below. Logstash is working fine without any issue but is there any way to put some message to know the logstash process, because I'm not getting any message after running following configuration file [if permission of TextFile.txt is anything other then 644].
I want to put some output message on terminal like "The permission of file is changed".

// Code started from here

                command => "stat -c '%a %n' TextFile.txt"
                interval => 60

                match => {"message" => "%{NUMBER:access} %{GREEDYDATA:filename}"}

        if[access] == "644"
                        command => "chmod 644 TextFile.txt"
                        quiet => false


bin/logstash -f demo.conf
