I'm getting this error: illegal\_argument\_exception: index.lifecycle.rollover\_alias Not sure what it means, looking at a previous ticket it seems like it needs to have an alias setup for something? Documentation hasn't been helping, please advise. ---

Can you post the entire error? It seems like there is part of that that's missing (such as the message about why it was illegal or where it came from) ---

Hey, sorry this took way too long! illegal\_argument\_exception: index.lifecycle.rollover\_alias [filebeat-rollup-3] does not point to index [filebeat-6.7.1-2019.05.07] ---

If your lifecycle policy has a [Rollover action](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/_actions.html#ilm-rollover-action) defined in the Hot phase, then yes, the alias specified by `index.lifecycle.rollover_alias` must be set to an alias which points to that index before rollover. Given that your index has `index.lifecycle.rollover_alias` set to `filebeat-rollup-3`, is there a possibility that you've confused [Rollover](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/indices-rollover-index.html) (which swaps out the index backing an alias for a new one) with [Rollup](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/rollup-overview.html) (which stores historical data at reduced granularity)? They are named very similarly, and are often used in a similar context (both are mainly used for timeseries-style data, such as logs or metrics), but do very different things. ---

Thanks! I'll look at this. ---
