Logstash not importing data even after showing absolutely fine logs

[KashiPashoria_Tonny]

I'm using elasticsearch 6.6.0 and same version of logstash to import a csv file. I wrote a config file for logstash as it should be. It shows absolutely fine logs. Ending logs are as follows:

[2019-02-12T19:52:40,089][INFO ][logstash.pipeline ] Pipeline started successfully {:pipeline_id=>"main", :thread=>"#<Thread:0x94268e8 run>"}

[2019-02-12T19:52:40,172][INFO ][logstash.agent ] Pipelines running {:count=>1, :running_pipelines=>[:main], :non_running_pipelines=>[]}

[2019-02-12T19:52:40,197][INFO ][filewatch.observingtail ] START, creating Discoverer, Watch with file and sincedb collections

[2019-02-12T19:52:40,610][INFO ][logstash.agent ] Successfully started Logstash API endpoint {:port=>9600}

After these logs, it just doesn't do anything and doesn't even print a single log.
I need quick help. I've already wasted my 2 days sorting this issue out.

What does the configuration look like? If you are just using file inputs then running with --log.level trace will show you what the filewatchers are doing.

I ran logstash with --debug and is show ending logs as follows:

and it just goes on repeating this. Don't get to know about cgroup files or directories.

As I said, use --log.level trace, not --log.level debug. You can ignore the cgroup messages.

[KashiPashoria_Tonny]

yes I figured it out searching against the logs that were printed using --log.

Thanks for your help.
