Logging Configuration

Log Categories

# Configure logging in named.conf
logging {
    channel default_log {
        file "/var/log/named/default.log" versions 3 size 5m;
        severity info;
        print-time yes;
        print-severity yes;
        print-category yes;
    };
    
    category default { default_log; };
    category queries { default_log; };
    category security { default_log; };

Pro Tip: Configure appropriate log rotation to prevent log files from consuming excessive disk space.

Effective monitoring and logging provide visibility into DNS server operations and performance.
