I just installed Elastic Stack 7.2 using Azure ARM template and configured fiebeats to export data to it. Everything looks works pretty straightforward. I can see the logs from kibana's logs plugin and also see the metrics for beats and everything looks works well.
But, I can not create index patterns using filebeat-*, even the logs plugin are able to use the same pattern to show logs. I tried to both creating an index pattern manually and have filebeats to create it by importing some built-in filebeats dashboard, unfortunately, both failed.
The error message is
Failed to fetch Error: Failed to fetch at http://xxx.xxx.xxx.xxx:5601/bundles/commons.bundle.js:3:1605400
Also here is one snapshot to show all filebeat indices are healthy.
