internal() source options
This section describes the options of the internal() source in syslog-ng OSE.
The internal() driver has the following options:
host-override()
| Type: | string |
| Default: |
Description: Replaces the HOST part of the message with the
parameter string.
log-fifo-size()
| Type: | number |
| Default: | Use global setting. |
Description: The number of messages that the output queue can store.
log-iw-size()
| Type: | number |
| Default: | 100 |
Description: The size of the initial window, this value is used during flow-control. Its value cannot be lower than 100, unless the dynamic-window-size() option is enabled. For details on flow-control, see Managing incoming and outgoing messages with flow-control.
normalize-hostnames()
| Accepted values: | yes | no |
| Default: | no |
Description: If enabled (normalize-hostnames(yes)), syslog-ng OSE converts the hostnames to lowercase.
NOTE: This setting applies only to hostnames resolved from DNS. It has no effect if the keep-hostname() option is enabled, and the message contains a hostname.
program-override()
| Type: | string |
| Default: |
Description: Replaces the ${PROGRAM} part of the message with the parameter string. For example, to mark every message coming from the kernel, include the program-override("kernel") option in the source containing /proc/kmsg.
tags()
| Type: | string |
| Default: |
Description: Label the messages received from the source with custom tags. Tags must be unique, and enclosed between double quotes. When adding multiple tags, separate them with comma, for example, tags(“dmz”, “router”). This option is available only in syslog-ng OSE 3.1 and later.
use-fqdn()
| Accepted values: | yes | no |
| Default: | no |
Description: Use this option to add a Fully Qualified Domain Name (FQDN) instead of a short hostname. You can specify this option either globally or per-source. The local setting of the source overrides the global option if available.
TIP: Set use-fqdn() to yes if you want to use the custom-domain() global option.
NOTE: This option has no effect if the keep-hostname() option is enabled (keep-hostname(yes)) and the message contains a hostname.
