# Logs, metrics, and dashboard
<a name="logs-metrics-and-dashboard"></a>

The guidance establishes a log group named `/aws/solutions/druid/<cluster name>` in CloudWatch for storing various logs collected from EC2 instances. These logs include:
+ Druid process logs from EC2 instances
+ ZooKeeper process logs
+ System initialization logs from EC2 instances

In addition, it also sets up a S3 bucket to store the logs gathered from AWS infrastructure and services, including:
+ VPC Flow Logs
+ ALB access logs
+ S3 bucket access logs

The guidance creates a metric namespace named `AWSSolutions/Druid` to store the metrics collected from EC2 instances. These metrics include:
+ Druid application metrics (e.g. ingestion/query throughput)
+ Operating system metrics (e.g. CPU/memory/disk utilization)

The guidance includes an Amazon CloudWatch dashboard named `druid-<cluster name>-ops-dashboard` configured to provide an overview of the health and operational status of all components in the guidance.
