In your index template, it shows below which seems incorrect > [@Akbar\_Maulana](#): > > ` "rollover_alias": "sonicwall-*"` rollover\_alias should be example `sonicwall` instead of having a `-*` inside Also your `logstash conf.d` `index =>` should point to your `rollover_alias` instead of `"sonicwall-%{+YYYY.MM.dd}"` If you wanted to add date to your index, you can take a look at this [post](https://discuss.elastic.co/t/index-lifecycle-rollover-alias-does-not-point-to-index/192525) or read up on [date math](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/indices-rollover-index.html#_using_date_math_with_the_rollover_api) This [document](https://www.elastic.co/guide/en/elasticsearch/reference/current/getting-started-index-lifecycle-management.html#manage-time-series-data-without-data-streams) helps me alot when I'm configuring ILM Hope this can help you! --- _[View the full topic](https://discuss.elastic.co/t/help-illegal-argument-exception-index-lifecycle-rollover-alias-sonicwall-does-not-point-to-index-sonicwall-2020-09-28-000001/250281)._
