Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
When configuring either a WAF Policy, or an Ingress resource with WAF Annotations, I would like to enable security logs, and have the logDest default to syslog:server=localhost:514

Describe the solution you'd like
A default value set for logDest

Describe alternatives you've considered
The only alternative is to explicitly set logDest: syslog:server=localhost:514 for all my Ingresses and/or VirtualServers

Hi @shaun-nx thanks for reporting!

Be sure to check out the docs and the Contributing Guidelines while you wait for a human to take a look at this 🙂

Cheers!

The bundled nginxAgent by default listens on port 1514. I believe that would be a better default value. Of course with an option to override it
