PreserveCase

Controls whether the case of fromhost is preserved.

This parameter applies to imtcp: TCP Syslog Input Module.

Name:

PreserveCase

Scope:

module, input

Type:

boolean

Default:

module=on, input=module parameter

Required?:

no

Introduced:

8.37.0

Description

This parameter controls the case in fromhost. If PreserveCase is set to “off”, rsyslog normalizes the resolved host name to lowercase, e.g., host1.example.org when the message was received from Host1.Example.Org. The default is “on” for backward compatibility.

The same-named input parameter can override this module setting.

Module usage

module(load="imtcp" preserveCase="off")

Input usage

input(type="imtcp" port="514" preserveCase="off")
