JSON logs not being uploaded

(Everett) #1

I've configured Filebeat to harvest some OpenShift Audit logs. The logs are in JSON format so I'm using the JSON Log input.

However, the logs simply aren't getting uploaded to ElasticSearch (via Logstash). Well...I'm unable to see them in Kibana when I search for "auditID", which is one of the fields as you can see from the Log output below. I've also included as much debugging info as I can think of below.

Can anyone spot any misconfiguration or anything else I might be missing?

Any other debugging tips for this?


# grep -A 9 filebeat.inputs /etc/filebeat/filebeat.yml
- type: docker
  containers.ids: '*'
  - add_docker_metadata: ~
  - add_host_metadata: ~
- type: log
    - /var/log/audit/openshift.log
  json.keys_under_root: true

Log output

# tail -f /var/log/audit/openshift.log

For testing purposes could you please set a different registry file for Filebeat and try to send the logs again with debug logging turned on. Please share the ouput of at least the first 20-30 seconds, so we can get an idea of what is happening in your instance.

You can set the registry file to a different path:

filebeat.registry: ${path.data}/test-registry

By setting it to a different path we can try to send events without losing where you left off. You can also delete the registry file, so Filebeat will reread everything it has encountered before. But for a first debug run it's not necessary.
First you could try sending it to a file input, to see if Filebeat is able to find and process your logs.

Sorry, I'm not very familiar with Beats at all. I don't really know what "try sending it to a file input" means. How would I do that?

Apparently, I am not familiar with the English language... I am sorry I meant file output. :slight_smile:
Just add the following snippet to your config and comment out the existing output config.

  path: "/path/to/the/input/filebeat"
  filename: filebeat
