I have a weird issue with folder permissions on my ubuntu server.
I have 2 users which need access to nginx logs, www-data (nginx) and dd-agent (datadog, a logging service).
I created a group logusers and added both users to that group, then I changed permissions as follows:
sudo chown -R dd-agent:logusers /var/log/nginx/
I can see the following for ls -l:
drwxr-xr-x 2 dd-agent logusers 4096 May 29 06:25 nginx
Then I check both the status of the dd-service and nginx-service, and both are fine, but after a couple of hours, datadog reports a permission denied error for opening a file inside /var/log/nginx/.
How can I make sure both users have proper access? Why does this change over time?
--Edit:
Restarting the datadog-agent service and checking its status again shows no permission errors. This is weird.

if you want your new created files to be created as the group you specified to the folder you could do the following
sudo chmod g+s /var/log/nginx/
this will set the SGID-Bit ( Set Group ID ) to the folder with the result that every new created file inside that folder will inherit the group of the folder.
