Hi,

I wrote a custom parser with dissect processor for collecting fail2ban-logs. Those are working fine for the servers where logs are being collected using filebeat however I am not sure how do I add those with where I have Elastic-Agent installed?

Any clue please?

TIA

Are you parsing in the processors in the filebeat or an ingest pipeline?

Are you using the Custom Logs Integration with the Agent?

You can use the Custom Logs Integration -\> Advanced -\> Processors

Nope I am ingesting the logs with filebeat and parsing with processor. I used dissect processor and wondering how do I replicate with servers using elatic-agent?

Since Elastic-Agent is using filebeat in the background wondering if I could modifty that config and pickup and parse the logs using my processor? My logs are being dumped in /var/log/fail2ban.log and here are my dissec\_processor

```auto
filebeat.inputs:
- type: log
  paths:
    - /var/log/fail2ban.log
  processors:
    - drop_event:
       when:
         contains:
           message: INFO
    - dissect:
        tokenizer: '%{timestamp} fail2ban.actions %{process.pid}: NOTICE %{application|string} %{action|string} %{source.ip|ip}'
        field: "message"

```
