Filebeat Fortinet module can't run

[aloalo2242 (Long Pham)]

Hi, I'm trying to ship Fortigate300E Log to my Elasticstack with topo: Fortigate syslog port 514 -> Filebeat (fortinet module) -> Elasticsearch -> Kibana. I have 2 question:

First, is it possible?

And when I run filebeat filebeat setup -e with config (below comment) , then it error Exiting: 1 error: error loading config file: invalid config: yaml: line 21: did not find expected key I have check and not find the cause. Hope to get help. Thanks

    [root@localhost ~]# filebeat setup -e

  #multiline.pattern: ^\[

  # Defines if the pattern set under pattern should be negated or not. Default is false.
  #multiline.negate: false

  # Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
  # that was (not) matched before or after or as long as a pattern is not matched based on negate.

I can't see anything immediately wrong with your config myself. Do you have any other modules enabled?
What if you run that again with filebeat -e -d "*" to enable debug?

Hi warkolm,

I have try debug by that command but it's still return: Exiting: 1 error: error loading config file: invalid config: yaml: line 21: did not find

[root@localhost ~]# filebeat modules list
Enabled:
fortinet

This is my full report ( Can't upload here cause limit characters)
