空Symfony的探查器？

Question

I recently discovered that my profiler is not working. Every time I try to open the profiler from /app_dev.php/_profiler/empty/search/results?ip=&limit=10 I get this empty profiler page:

With default and customc onfiguration. Here the custom one:

framework:
    profiler:
        dsn: 'file:/tmp/symfony-profiler'

And here a more precise configuration:

framework:
    profiler:
        dsn: "file:%kernel.root_dir%/../var/cache/%kernel.environment%/profiler"

No calls are stored in theprofiler. No log keep trace of what happens under the carpet.

Symfony needs the same file permissions to write the profiling data as it would for logs or the cache. Does Symfony write the files if the DSN is left at the default which would write them into var/cache/dev/profiler (or app/var with an older version).

It's also possible that the profiler service has been overridden, which can be checked with bin/console debug:container profiler and other such tools.
