So sorry!  That's my bad for trying to recall all of the necessary options for the `age` filtertype off the top of my head.

Add `"direction":"older"` into the filter, like this:

```
curator_cli --host 10.240.1.130 show_indices --filter_list '{"filtertype":"age","source":"name","timestring":"%Y.%m.%d","unit":"days","unit_count":30,"direction":"older"}'
```

or in the yaml file:

```
---
actions:
  1:
    action: delete_indices
    description: Delete indices with %Y.%m.%d in the name where that date is older than 30 days
    options:
      ignore_empty_list: True
    filters:
      - filtertype: age
        source: name
        timestring: '%Y.%m.%d'
        unit: days
        unit_count: 30
        direction: older
```
