Support module for external message modification modules¶
Module Name: mmexternal
Available since: 8.3.0
Author:Rainer Gerhards <rgerhards@adiscon.com>
Description:
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.
Action Parameters:
Note: parameter names are case-insensitive.
binary
The name of the external message modification plugin to be called. This can be a full path name.
interface.input
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
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
This is an expert parameter, just like the equivalent omprog parameter. See the message modification plugin’s documentation if it is needed.
Caveats/Known Bugs:
- None.
Sample:
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")
