 ## Step 3: Generate `httpd` Access Logs
 
 Use `curl` command to generate some access logs like this:
 
 ```text
-$ curl http://localhost:80/[1-10]
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
-<html><body><h1>It works!</h1></body></html>
+$ curl http://localhost:8080/
 <html><body><h1>It works!</h1></body></html>
 ```
 
 ## Step 4: Confirm Logs from Kibana
 
-Browse to `http://localhost:5601/app/management/kibana/indexPatterns` and set up the index name pattern for Kibana. Specify `fluentd-*` to `Index name or pattern` and click `Create`.
+Browse to [`http://localhost:5601/app/discover#/`](http://localhost:5601/app/discover#/) and create data view.

-![Kibana Index](../.gitbook/assets/7.10_efk-kibana-index.png) ![Kibana Timestamp](../.gitbook/assets/7.10_efk-kibana-timestamp.png)
+Specify `fluentd-*` to `Index pattern` and click `Save data view to Kibana`.
+![Kibana Discover](../.gitbook/assets/8.17_efk-kibana-create-data-view.png)
 
 Then, go to `Discover` tab to check the logs. As you can see, logs are properly collected into the Elasticsearch + Kibana, via Fluentd.
