Hi all, **DESCRIPTION** I have two logs 2 send to logstash. But these two logs available in two servers due load balancing. So I send them all to centralized logstash server as follows ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/d/4d55e3c34b0aaf7de21923ee8d4774e32a95a772.png) ## following is my filebeat config of two servers filebeat.prospectors: - input\_type: log output.logstash: hosts: ["172.26.29.126:5044"] * * * I start filebeat in both servers as follows sudo /etc/init.d/filebeat start Out put is 2017/11/03 03:49:20.024553 beat.go:192: INFO Setup Beat: filebeat; Version: 5.6.3 2017/11/03 03:49:20.024660 metrics.go:23: INFO Metrics logging every 30s 2017/11/03 03:49:20.024730 logstash.go:90: INFO Max Retries set to: 3 2017/11/03 03:49:20.024908 outputs.go:108: INFO Activated logstash as output plugin. 2017/11/03 03:49:20.025080 publish.go:300: INFO Publisher name: ####### 2017/11/03 03:49:20.025387 async.go:63: INFO Flush Interval set to: 1s 2017/11/03 03:49:20.025413 async.go:64: INFO Max Bulk Size set to: 2048 **ISSUE** But my kibana dashboard doesn't update real time.

What does it look like if you change the time-picker to show the `last 4 hours` with a 30 second refresh interval instead of `today`? What is the load on the host where Elasticsearch, Kibana and Elasticsearch is installed (CPU and disk I/O)? What does your Logstash config look like? ---
