</div>

this's my logstash output:

```bash
    "prometheus" => {   
        "metrics" => {
             "container_cpu_load_average_10s" => 0,
             "container_cpu_user_seconds_total" => 18.15,
             "container_cpu_system_seconds_total" => 12.64
        }
    },

```

now I want use one statement like this:

```bash
mutate {
          rename => {
              "[prometheus][metrics][.*]" => "[.*]"
          }
}

```

to implement like this:

```bash
mutate {
          rename => {
             "[prometheus][metrics][container_cpu_load_average_10s]" => "[container_cpu_load_average_10s]"
             "[prometheus][metrics][container_cpu_user_seconds_total]" => "[container_cpu_user_seconds_total]"
             "[prometheus][metrics][container_cpu_system_seconds_total]" => "[container_cpu_system_seconds_total]"
          }
}

```

Can you help me?Pls!

You could rename a variable set of fields using a filter like [this](https://discuss.elastic.co/t/how-to-dynamically-move-nested-key-value-to-root-level/180006/2).
