Elasticsearch ILM delete not working

1. 检查 policy.delete.actions是否为空 

   

{
  "test-kibana-index-lifecycle-policy" : {
    "version" : 3,
    "modified_date" : "2021-05-18T06:27:51.498Z",
    "policy" : {
      "phases" : {
        "hot" : {
          "min_age" : "0ms",
          "actions" : {
            "set_priority" : {
              "priority" : 100
            }
          }
        },
        "delete" : {
          "min_age" : "30d",
          "actions" : {
            "delete" : {
              "delete_searchable_snapshot" : true
            }
          }
        }
      }
    }
  }
}

　　

2. 检查 ILM的 operation_mode

GET _ilm/status

{
  "operation_mode" : "RUNNING"
}

　　

3. 检查index的状态

{
  "indices" : {
    "logstash-2021.02.26" : {
      "index" : "logstash-2021.02.26",
      "managed" : true,
      "policy" : "test-kibana-index-lifecycle-policy",
      "lifecycle_date_millis" : 1619145416884,
      "age" : "25.18d",
      "phase" : "hot",
      "phase_time_millis" : 1621319688074,
      "action" : "complete",
      "action_time_millis" : 1621319688108,
      "step" : "complete",
      "step_time_millis" : 1621319688108,
      "phase_execution" : {
        "policy" : "test-kibana-index-lifecycle-policy",
        "phase_definition" : {
          "min_age" : "0ms",
          "actions" : {
            "set_priority" : {
              "priority" : 100
            }
          }
        },
        "version" : 3,
        "modified_date_in_millis" : 1621319271498
      }
    }
  }
}

　　由于age不到30天，所以没有删除，可以设置index.lifecycle.origination_date （parse_origination_date） 来保证时间计算正确
