Controls how logging of IP addresses is performed.
RequestId allowed values:
Can be set in: collection.cfg
Controls how the search interface will log search request IP addresses. The
userid_to_log setting accepts the
ip: log request IP addresses as normal
ip_hash: log a unique one-way hash of each incoming request IP address
nothing: do not log request IP addresses
Some of the query reports rely on the IP addresses to extract information about users. If the IP address is not logged or is logged as a hash, these reports will display unknown.
