Elasticsearch - ELK Stack Integration

Given this ingest pipeline snippet, what will be the value of the field 'log_level' after processing?

{"processors": [{"set": {"field": "log_level", "value": "INFO"}}, {"set": {"field": "log_level", "value": "ERROR"}}]}

AINFO, ERROR

BINFO

Cnull

DERROR

Step-by-Step Solution

Solution:

Step 1: Analyze processor order
The first processor sets 'log_level' to 'INFO', then the second overwrites it to 'ERROR'.
Step 2: Understand field overwrite behavior
Each processor runs sequentially; later 'set' overwrites previous values.
Final Answer:
ERROR -> Option D
Quick Check:
Last processor value wins = ERROR [OK]

Quick Trick: Later processors overwrite earlier field values [OK]
