Hi @Ravi_Pattar
I can not keep up with all your questions on this Topic. You need to read / learn our documentation, concepts etc...
Those are daily indices and thus NOT under ILM... With rollover
You can attempt to run
POST filebeat-7.17.5/_rollover
And 8.x Elastic Handles all this slightly different with Datastreams and if you are mizxing 7.x and 8.x Beats vs Logstash vs Elasticsearch you may have issues...
If you use 8.x Elasticsearch and Logstash you will need to use the output config shown on this page....
And learn about datastreams which in. 8.x replaces much of what we have discussed in this topic
Heads up I will not be answering more question on this topic... .
If you have new specific questions please open new specific questions
