Support module for external message modification modules¶
| Module Name: | mmexternal |
| Author: | Rainer Gerhards <rgerhards@adiscon.com> |
| Available since: | 8.3.0 |
Purpose¶
This module permits to integrate external message modification plugins into rsyslog.
For details on the interface specification, see rsyslog’s source in the ./plugins/external/INTERFACE.md.
Configuration Parameters¶
Note
Parameter names are case-insensitive.
Action Parameters¶
binary¶
| type | default | mandatory | obsolete legacy directive |
|---|---|---|---|
| string | none | yes | none |
The name of the external message modification plugin to be called. This can be a full path name.
interface.input¶
| type | default | mandatory | obsolete legacy directive |
|---|---|---|---|
| string | msg | no | none |
This can either be “msg”, “rawmsg” or “fulljson”. In case of “fulljson”, the message object is provided as a json object. Otherwise, the respective property is provided. This setting must match the external plugin’s expectations. Check the external plugin documentation for what needs to be used.
output¶
| type | default | mandatory | obsolete legacy directive |
|---|---|---|---|
| string | none | no | none |
This is a debug aid. If set, this is a filename where the plugins output is logged. Note that the output is also being processed as usual by rsyslog. Setting this parameter thus gives insight into the internal processing that happens between plugin and rsyslog core.
forceSingleInstance¶
| type | default | mandatory | obsolete legacy directive |
|---|---|---|---|
| binary | off | no | none |
This is an expert parameter, just like the equivalent omprog parameter. See the message modification plugin’s documentation if it is needed.
Examples¶
Execute external module¶
The following config file snippet is used to write execute an external message modification module “mmexternal.py”. Note that the path to the module is specified here. This is necessary if the module is not in the default search path.
module (load="mmexternal") # needs to be done only once inside the config
action(type="mmexternal" binary="/path/to/mmexternal.py")
