Logstash permission issue and need help on this

Elastic Stack Logstash

Hi Folks,

I have directory /var/log/data where my files are being written and those are the docker volumes.

drwxrwxr-x 25 pbdocker pbdocker 4096 Sep 29 02:49 data

When I am trying to run the logstash to read the files inside data folder I am getting below error. Wondering what permission would be appropriate to make it work?

It is able to find the file, so the permissions on /var/log/data, /var/log/data/p0f, and /var/log/data/p0f/log must be OK. The problem is the permissions on the file itself. logstash needs read access to it.
