Hi there,

My Index-Lifecycle management functionality is not working as I would expect.

The ILM is trying to roll-over the following indexes, but I'm getting the following error.  
illegal\_argument\_exception: index name [metricbeat-7.3.1] does not match pattern '^.\*-\d+' AND illegal\_argument\_exception: index name [mon\_servicelog-2020.06] does not match pattern '^.\*-\d+'

I already found some documentation explaining that the index needs to end in an incrementable number, but is there a way around this, by for example changing the pattern in the backend ?

Thanks in advance

Do you have an existing ILM setup or are you starting from scratch?

Hi, we already have an existing ILM (with 7 different policies).
