Elasticsearch - ELK Stack Integration

Identify the error in this pipeline configuration snippet:

{
  "input": { "type": "file", "path": "/var/log/app.log" },
  "filter": { "grok": { "match": { "message": "%{TIMESTAMP_ISO8601:timestamp} %{LOGLEVEL:level}" } } },
  "output": { "elasticsearch": { "index": "app-logs" }
}

AInput type 'file' is invalid

BIncorrect grok pattern syntax

COutput index name cannot contain hyphens

DMissing closing brace for the output section

Step-by-Step Solution

Solution:

Step 1: Check JSON structure
The output section is missing a closing brace '}' at the end, causing invalid JSON.
Step 2: Validate other parts
The grok pattern syntax is correct, input type 'file' is valid, and index names can have hyphens.
Final Answer:
Missing closing brace for the output section -> Option D
Quick Check:
JSON braces must be balanced [OK]

Quick Trick: Check all braces and commas in JSON config [OK]

Common Mistakes:

MISTAKES

Ignoring missing braces causing syntax errors
Assuming grok pattern is wrong without checking
