Logging

NGINX Instance Manager Server uses the system logging process to write log files, usually to /var/log/nms. To prevent your system from running out of space due to log growth, we recommend using a separate partition for the logs or and/or enabling log rotation.

The NGINX Agent uses the log files and formats to collect metrics. Expanding the log formats and instance counts will also increase the size of the log files on the NGINX Agent. Adding a separate partition for /var/log/nginx-agent is always a good idea. Without log rotation or a separated partition, a log directory could cause your system to run out of space.
