Hi Team,
We are using the ELK stack and we are getting the below error in our logstash pods logs .
Logs are sending slowly or some time it is not at all processing the logs .
Note: We checked the elasatic search service local host and it is up and running all the time though the error was captured.
**Version we used in our platform:**
Elasticsearch - Elasticsearch:7.4.2
Logstash - logstash:6.8.22
kibana - kibana:7.4.2
Elasticsearch-cluster-data 17 nodes
Elasticsearch-cluster-master 3 nodes
**Error Message in logstash:**
