log_zmq_off
The `log_zmq_off` directive disables ZeroMQ logging for a specific location in the NGINX configuration.
Description
The log_zmq_off directive is used within the context of a location block in the NGINX configuration. It allows users to selectively mute logging for specific requests based on the location being accessed. This can be particularly useful when certain endpoints are used for high-volume requests or health checks where logging is unnecessary or could cause unwanted overhead. The directive takes one argument, which is the name of the log server configuration that should be turned off. If the argument is 'all', logging for all configured ZeroMQ servers will be disabled for that location.
When log_zmq_off is set, NGINX will not send any log messages related to the specified server or all servers, depending on the argument provided. This feature is crucial for optimizing performance and ensuring that log-related operations do not interfere with the normal handling of incoming requests, especially in environments where bandwidth or processing power is limited. The directive can be applied multiple times with different arguments to manage logging dynamically across various locations in the NGINX configuration.
Config Example
location /status {
log_zmq_off all;
}
location /endpoint {
log_zmq_off main;
}Ensure the server name is correct to avoid unwanted logging; using 'all' will silence all loggers for that location.
Using this directive without considering performance implications may result in loss of important log data.
