Hi All,

I've the following errors il eleastic log files for the indexes Lifecycle Management for the indexes and don't know how to solve them...
Could someone give me some clues?

Thanks,

Moving to ERROR step*

Please share your policy and template.

Hi Mark,

For the policy :

PUT _ilm/policy/filebeat
{
"policy": {
"phases": {
"hot": {
"min_age": "0ms",
"actions": {
"rollover": {
"max_age": "30d",
"max_size": "50gb"
},
"set_priority": {
"priority": null
}
}
}
}
}
}

For the index pattern: filebeat-7.8.0-* linked to ILM Policy filebeat

Index Template Name : filebeat-7.8.0

Head of filebeat-7.8.0 settings:
{
"index": {
"lifecycle": {
"name": "filebeat",
"rollover_alias": "filebeat-7.8.0"
},
"mapping": {

"limit": "10000"
}
},
"refresh_interval": "5s",
"number_of_shards": "1",

Hope this can help,

Just make sure you bootstrap your first index - https://www.elastic.co/guide/en/elasticsearch/reference/current/getting-started-index-lifecycle-management.html#ilm-gs-alias-bootstrap
