Additional Information

NGINX will need configuration for a specific log format. This is normally done in the nginx.conf file. Documentation for the ngx_http_log_module can be found at http://nginx.org/en/docs/http/ngx_http_log_module.html

Configure Log Format Directive NGINX Docs

Code Block

'devTime=$time_local\t'
'devTimeFormat=dd/MMM/yyyy:HH:mm:ss Z\t'

Configure Access Log Directive NGINX Docs

Code Block
access_log /var/log/nginx/access.log armor_202004;
Note

Configure Access Log Directive will create a filename that is then used with the command:

Code Block

firstline1
armor logging nginx-add-access-paths
