internal: Collect internal messages
All messages generated internally by AxoSyslog use this special source. To collect warnings, errors and notices from AxoSyslog itself, include this source in one of your source statements.
The AxoSyslog application will issue a warning upon startup if none of the defined log paths reference this driver.
Example: Using the internal() driver
source s_local { internal(); };
The AxoSyslog application sends the following message types from the internal() source:
-
fatal: Priority value: critical (2), Facility value: syslog (5)
-
error: Priority value: error (3), Facility value: syslog (5)
-
warning: Priority value: warning (4), Facility value: syslog (5)
-
notice: Priority value: notice (5), Facility value: syslog (5)
-
info: Priority value: info (6), Facility value: syslog (5)
1 - internal() source options
The internal() driver has the following options:
host-override()
Description: Replaces the ${HOST} part of the message with the parameter string.
log-iw-size()
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)), AxoSyslog converts the hostnames to lowercase.
program-override()
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.
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 version 3.1 and later.
use-fqdn()
| |
| Type: | yes or no |
| Default: | no |
Description: Add Fully Qualified Domain Name instead of short hostname. This option can be specified globally, and per-source as well. The local setting of the source overrides the global option if available.
