Hi. We've been creating our index daily with the following pattern 'test-logs-_date_'. For example, today's index would be 'test-logs2019.07.22'.

I tried implementing Index Lifecycle Management/Index Lifecycle Policies and when the ILP was linked to the index, I got the following error:

"failed\_step" : "check-rollover-ready",  
"step\_info" : {  
"type" : "illegal\_argument\_exception",  
"reason" : "index name [test-logs-2019.07.19] does not match pattern '^.\*-\d+'", "stack\_trace" : """ java.lang.IllegalArgumentException: index name [test-logs-2019.07.19] does not match pattern '^.\*-\d+'  
at org.elasticsearch.action.admin.indices.rollover.TransportRolloverAction.generateRolloverIndexName(TransportRolloverAction.java:236)  
…  
…

I saw this when I executed "GET test-logs-2019.07.19/\_ilm/explain".

We are using ELK 7.0.

I know that in using the ILP/ILM, the index name should end in an incremental number, i.e. test-logs-0001. And this is where my issue is. My question is, is there a way to use ILP/ILM on indices that ends with the date instead of an incremental number?

Hi,  
Does anyone have an idea on how I can fix this issue and use a different pattern for index?
