Hi all,
I am using ELK version 7.12.1 to harvest data using filebeat and then send them logstash.
I have two nodes of logstash (10.0.0.1:5044 and 10.0.0.2:5044)
My filebeat output config is as following:
```auto
output.logstash:
# The Logstash hosts
hosts: ["10.0.0.1:5044" , "10.0.0.2:5044" "]
loadbalance: true
worker: 2
```
When I check Elasticsearch, It seems some events have been lost. To understand what is happening, I change logging level of filebeat to debug. Based on the logs, filebeat harvest the lost logs but following message has been found in the log which cannot connect to logstash:
It is noted that nothing has been found in the logstash log at the issue time.
