10.15 Do not resolve hosts on logging valves

Information

Setting enableLookups to true on Connector will result in a DNS look-ups to obtain the host name of the remote client before logging any information. This uses additional resources when logging.

Rationale:

Allowing enableLookups adds additional overhead to resolve the host name of a remote client which is rarely needed.

Solution

In Connector elements, set the enableLookups attribute to false or remove it.

<Connector ... enableLookups='false' />

Default Value:

By default, DNS lookups are disabled.
