Lifecycle Management rotate on a daily basis

[gruselglatz]

How do i correctly config ILM to rotate my index on a daily basis and delete the index after 120 days?

I tried this config, but it doesn't rotated the index:

"logstash" : {
    "version" : 1,
    "modified_date" : "2019-03-27T11:42:32.848Z",
    "policy" : {
      "phases" : {
        "warm" : {
          "min_age" : "14d",
          "actions" : {
            "allocate" : {
              "number_of_replicas" : 0,
              "include" : { },
              "exclude" : { },
              "require" : { }
            }
          }
        },
        "hot" : {
          "min_age" : "0ms",
          "actions" : {
            "rollover" : {
              "max_size" : "50gb",
              "max_age" : "1d"
            }
          }
        },
        "delete" : {
          "min_age" : "120d",
          "actions" : {
            "delete" : { }
          }
        }
      }
    }
  }

Hi Gruselglatz,

The policy looks correct to me, can you use the ILM Explain API on the index to see what's going on, should be:

GET /<index-name>/_ilm/explain?pretty&human

This will give us an idea of where the policy is and whether it's hit any errors while executing.

Hi dakrone!

it looks like its rotating now, but with one day delay.
I get this now:

Real Date -> index name
28.03.2019 -> logstash-2019.03.27-000001
29.03.2019 -> logstash-2019.03.28-000002
30.03.2019 -> logstash-2019.03.29-000003
31.03.2019 -> logstash-2019.03.30-000004
01.04.2019 -> logstash-2019.03.31-000005

but what i want to get is:
Real Date -> index name
28.03.2019 -> logstash-2019.03.28-000001
29.03.2019 -> logstash-2019.03.29-000001
30.03.2019 -> logstash-2019.03.30-000001
31.03.2019 -> logstash-2019.03.31-000001
01.04.2019 -> logstash-2019.04.01-000001

And when i get over xx million docs the index should rotate on the same day and increment the last number.

the output of the API-call:

GET /logstash-2019.03.31-000005/_ilm/explain?pretty&human

            }
          }
        },

    }
  }
}

@dakrone do you know something new? I think it should be fixable by configuring the rotation time to midnight every day and not 1PM afternoon.

how could I achieve it?
