@devuser, Could you look at the solution in this thread and OpenSearch documentation?

Missing Alias On Rollover

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): Opensearch-2.12.0 Dashboard-2.12.0 RHEL-8.8 Microsoft Edge-128.0.2739.67 The issue: I am experiencing the “Missing rollover_alias index setting [index=tomcat-000004]” error while rolling over the index. I’ve configured an alias named “tomcat_write” and make Logstash index the logs to “tomcat_write”. I am able to manually rollover my latest index (tomcat-000003 for example), the manual rollover action works fine and creates next …

Index rollups

I think you should use plugins.index_state_management.rollover_alias instead of index.plugins.index_state_management.rollover_alias

[devuser]

@pablo Can you explain me the solution ?

When I

PUT producer-server-000001
{
  "aliases": {
    "producer-server": {
      "is_write_index": true
    }
  },
  "settings": {
    "index.plugins.index_state_management.rollover_alias": "producer-server"
  }
}

this solves the problem.

is there any issue with my order. What is actually going wrong?

Any opensearch expert please explain?

[pablo]

@devuser Please take a look at the rollover example in the OpenSearch documentation.

Policies

@devuser

  "settings": {
    "index.plugins.index_state_management.rollover_alias": "producer-server"
  }

According to the documentation, it should be

  "settings": {
    "plugins.index_state_management.rollover_alias": "producer-server"
  }
