Logstash pipeline not working with csvfile

问题

set it up like below

wget https://artifacts.elastic.co/downloads/logstash/logstash-6.6.2.deb
sudo dpkg -i logstash-6.6.2.deb
sudo systemctl enable logstash.service
sudo systemctl start logstash.service

and i added a pipeline script like below

input {
        file {
                path => "/root/dev/Intuseer-PaaS/backend/airound_sv_logs.log"
                start_position => "beginning"
        }
}
output {
        stdout {}
        file {
                path => "/root/dev/output/output-%{+YYYY-MM-dd}.log"
        }
}

the log file likes below

timestamp, server_cpu, server_memory_used, server_memory_free, process_cpu, process_memory
1582787287, 1, 1176, 2759, 0, 9.05

So, in summary, everything was working, but since you didn't see anything in the log you assumed it wasn't working. Adding --debug confirmed that everything was working properly.

A few notes, though:

• Don't forget to add sincedb_path otherwise you run the risk of not being able to reprocess your file repeatedly
• Try not to do stuff in /root as the use under which Logstash runs might not always have the right to R/W that folder
• Leverage the csv filter in order to parse your rows.
