I have attached my filebeat which was taken from [https://github.com/elastic/beats/blob/6.5/deploy/kubernetes/filebeat-kubernetes.yaml](https://github.com/elastic/beats/blob/6.5/deploy/kubernetes/filebeat-kubernetes.yaml) + Added ES endpoint with creds + disabled filebeat.config.inputs + enabled autodiscover + added annotations.  
I was hoping the NGINX logs would get parsed, but they don't seem to be. Logged here [https://github.com/elastic/beats/issues/9768](https://github.com/elastic/beats/issues/9768).

Anybody who has come across this?

autodiscover:

```auto
filebeat.autodiscover:
      providers:
        - type: kubernetes
          hints.enabled: true

```

annotations:

```auto
spec:
  template:
    metadata:
      labels:
        app: filebeat
      annotations:
        co.elastic.logs/module: nginx
        co.elastic.logs/fileset.stdout: access
        co.elastic.logs/fileset.stderr: error

```

Hey @sujituk

Those annotations you've mentioned will want to go on the pods that are producing the Nginx logs, rather than the Filebeat Daemonset:

```auto
co.elastic.logs/module: nginx
co.elastic.logs/fileset.stdout: access
co.elastic.logs/fileset.stderr: error

```

This way you can customise the parsing behaviour for logs on a per pod basis.

@Evesy Got it. I will try that and keep you posted.  
The logformat is a customized one from the kubernetes nginx controller

```auto
log_format upstreaminfo
    '{{ if $cfg.useProxyProtocol }}$proxy_protocol_addr{{ else }}$remote_addr{{ end }} - '
    '[$the_real_ip] - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" "$http_user_agent" '
    '$request_length $request_time [$proxy_upstream_name] $upstream_addr '
    '$upstream_response_length $upstream_response_time $upstream_status $req_id';

```

Do you think this should be sent to a logstash pipeline with appropriate grok format? Currently, I'm sending it directly to elasticsearch and expecting the grokking to happen.

We have the same usecase @sujituk

We created a custom filebeat module specifically for ingress nginx, and in that module included an Elasticsearch ingest pipeline that would do the processing for us (Grok field parsing + GeoIP processing + User agent processing) .  
The docs here can help getting your own module created: [https://www.elastic.co/guide/en/beats/devguide/current/filebeat-modules-devguide.html](https://www.elastic.co/guide/en/beats/devguide/current/filebeat-modules-devguide.html) Also happy to assist if you have any questions.

You could of course just send to Logstash if it's easier for you, however I prefer the integration with Filebeat & Ingest pipelines
