NLog save entries to database(postgresql),

Question

Search on many post, all compared to almost identical but somehow its doesn't send entries to DB.

logging file works, but database not..

nlog.config

<?xml version="1.0" encoding="utf-8" ?>

Api project gets dbcontext from data layer so does Npgsql reference

here is API nugget refs;

and data layer packages;

here are some contents of "internallog.txt";

whats missing here?

Answer 1

There isn't a rule that writes to the database target in your config.

E.g. Replace

<logger name="*" minlevel="Trace" writeTo="ownFile-web" />

With

<logger name="*" minlevel="Trace" writeTo="ownFile-web, database" />
