Elasticsearch - Index Management

You want to create an ILM policy that:
- Rolls over an index at 30GB or 15 days
- Moves the index to warm phase after rollover
- Deletes the index 60 days after rollover

Which policy configuration correctly implements this?

A{"phases": {"hot": {"actions": {"rollover": {"max_size": "30gb"}}}, "warm": {"min_age": "30d", "actions": {}}, "delete": {"min_age": "60d", "actions": {"delete": {}}}}}

B{"phases": {"hot": {"actions": {"rollover": {"max_age": "15d"}}}, "warm": {"min_age": "15d", "actions": {"shrink": {}}}, "delete": {"min_age": "60d", "actions": {"delete": {}}}}}

C{"phases": {"hot": {"actions": {"rollover": {"max_size": "30gb", "max_age": "15d"}}}, "warm": {"min_age": "15d", "actions": {}}, "delete": {"min_age": "60d", "actions": {"delete": {}}}}}

D{"phases": {"hot": {"actions": {"rollover": {"max_size": "15gb", "max_age": "30d"}}}, "warm": {"min_age": "15d", "actions": {}}, "delete": {"min_age": "60d", "actions": {"delete": {}}}}}

Step-by-Step Solution

Solution:

Step 1: Verify rollover conditions
{"phases": {"hot": {"actions": {"rollover": {"max_size": "30gb", "max_age": "15d"}}}, "warm": {"min_age": "15d", "actions": {}}, "delete": {"min_age": "60d", "actions": {"delete": {}}}}} uses max_size 30gb and max_age 15d, matching requirements.
Step 2: Check warm and delete phases
Warm phase starts at 15d (after rollover), delete at 60d, as required.
Step 3: Confirm other options
Other options have wrong sizes, ages, or missing actions.
Final Answer:
{"phases": {"hot": {"actions": {"rollover": {"max_size": "30gb", "max_age": "15d"}}}, "warm": {"min_age": "15d", "actions": {}}, "delete": {"min_age": "60d", "actions": {"delete": {}}}}} -> Option C
Quick Check:
Rollover at 30gb/15d, warm at 15d, delete at 60d = B [OK]

Quick Trick: Match rollover size and age, then warm and delete min_age [OK]

Common Mistakes:

MISTAKES

Swapping max_size and max_age values
Setting warm min_age too late
Missing delete action or wrong min_age
