[Solved]Logparser Permissions are correct, there's still a permission error

Telegraf

The logparser has trouble getting the NGINX logs located at /var/log/nginx/*_access.log due to denied permissions.

Logparser output:
Nov 10 21:39:30 central telegraf[16781]: 2018-11-10T21:39:30Z E! Error in plugin [inputs.logparser]: open /var/log/nginx/stats_access.log: permission denied

File permissions:
-rw-r--r-- 1 www-data www-data 276585 Nov 10 00:19 /var/log/nginx/stats_access.log

telegraf user groups:
telegraf : telegraf www-data docker

Version: Telegraf 1.8.3 (git: HEAD f2979106)

I can provide further info if needed…

Additionally, it doesn’t find any files by pattern /var/log/nginx/*_access.log unless i use /var/log/nginx/**.log

I have files that are matched by the pattern /var/log/nginx/*_access.log

Example:

ls -l /var/log/nginx/*_access.log

Fixed it myself, had to run the service as root even if the parser had enough permissions, not sure what the reason behind it is.
