====== Networking - DNS - Unbound - Logging ======

Specify the log file and the verbosity level in the server part of the Unbound configuration file.

For example:

<file bash /etc/unbound/unbound.conf.d/pi-hole.conf>
server:
    # If no logfile is specified, syslog is used.
    logfile: "/var/log/unbound/unbound.log"
    verbosity: 1
</file>

<WRAP info>
**NOTE:**  It is not recommended to increase verbosity for daily use, as unbound logs a lot.

But it might be helpful for debugging purposes.

The levels of verbosity:

  * Level 0 means no verbosity, only errors
  * Level 1 gives operational information
  * Level 2 gives  detailed operational  information
  * Level 3 gives query level information
  * Level 4 gives  algorithm  level  information
  * Level 5 logs client identification for cache misses
