<match **>
  @type elasticsearch
  host elasticsearch
  port 9200
</match>

AFluentd config uses <source> instead of <match>

BFluentd service account lacks permissions to access logs

CKibana is not running

DElasticsearch host name is incorrect or unreachable

Step-by-Step Solution

Solution:

Step 1: Check connectivity to Elasticsearch
If the host name is wrong or unreachable, Fluentd cannot send logs.
Step 2: Verify other options
Permissions affect log collection, not sending; Kibana is for visualization; config uses correctly.
Final Answer:
Elasticsearch host name incorrect or unreachable -> Option D
Quick Check:
Check Elasticsearch host connectivity first [OK]

Quick Trick: Verify Elasticsearch host is reachable from Fluentd [OK]
