That means access log of all the virtual host will be recorded in the same file. The access log is enabled by default in the http context of core NGINX configuration file.

Therefore if NGINX is unable to start or abruptly stopped running then you should check the error logs to find more details. This may happen if there is some error in the configuration file.

On the other hand, if NGINX faces any glitches then it will record the event to the error log. Further, by monitoring the access logs properly, one can find out if an user is sending some unusual request for finding flaws in the deployed web application. It is possible to use the information from access log to analyze the traffic to find sites usages over time.

Once v7.7 is out, it should contain the ingress_controller fileset which will extract better metadata from the log output. This will send all the nginx-ingress logs to your Elasticsearh cluster. I'm not going to cover setting up Elasticsearch and Kibana here. In your nf file, you will find a directive that resembles the. As a result, you may decide that you want to disable it. However, this log can take up disk space and increase the number of disk writes that your server is performing. The main difficulty was figuring out how to make the nginx module process the log output of the container input correctly, and also finding out that the ingress_controller fileset for nginx does not actually exist in v7.6.2, which was the latest at time of writing.
