Hi,

Trying to get my head around ILM.

My beats are ingested via logstash. When updating beats i point them at elasticsearch to add the new index etc.

My logstash index pattern is along the files of filebeat-version-source-tenantid  
Example filebeat-7.5.0-ngfw-id00001

I have created with the bootstrap for now with:

PUT filebeat-7.5.0-ngfw-id0001-000001  
{  
"aliases": {  
"filebeat-rollover":{  
"is\_write\_index": true  
}  
}  
}

The multi-tenancy is the main issue, do I have to do this for every index I will be generating?

Thanks  
Phil
