Post-Install Verification for Elastic Cluster Health

Verify that the dashboard exists

Navigate to the Elasticsearch cluster health monitoring dashboard.

Steps:

1. Login to Kibana.
2. Navigate to Dashboards
3. Use the search bar to search for Monitoring Agents and open the dashboard
4. Click on Cluster Overview.
5. Alternatively, visit this direct link: http://<hostname_or_ip>:5601/app/monitoring#

Expected Result:

• Successfully access the Elasticsearch monitoring dashboard.
• Cluster health panels and metrics are visible.
• Dashboard loads without errors.

Verify cluster health summary

Confirm cluster health status, total nodes, shards, indices, and document count are displayed and accurate.

Steps:

1. Locate the Cluster Health Summary panel.
2. Validate:
   • Cluster status (Green, Yellow, Red) — expect Green for healthy cluster.
   • Number of nodes.
   • Number of indices.
   • Total shards and unassigned shards.
   • Total documents.
   • Data size.

Expected Result:

• Cluster health is Green (Healthy).
• Nodes, shards, indices, and documents display current, non-zero values.
• No unassigned shards.
• Data size is displayed accurately.

Verify node metrics

Ensure node-level metrics such as CPU usage, JVM heap usage, and disk space are reported per node.

Steps:

1. Open the Node Metrics or Elasticsearch Nodes panel.
2. Confirm each node shows:
   • Status (Online).
   • CPU usage (percentage).
   • JVM heap usage (percentage).
   • Disk free space.
   • Load Average (may be unavailable, verify if data present).

Expected Result:

• All nodes listed.
• CPU, JVM heap %, and disk free space values present.
• Load average may show as N/A if unsupported but should be monitored for future inclusion.

Verify index statistics

Validate index-level metrics including document counts, data size, indexing rate, and search rate.

Steps:

1. Open the Indices panel.
2. Review per-index data such as:
   • Document count.
   • Data size.
   • Indexing rate (docs per second).
   • Search rate (queries per second).
   • Unassigned shards (should be zero).
3. Check for any alerts or warnings on indices.

Expected Result:

• Per-index document counts and data sizes are populated.
• Indexing and search rates update regularly.
• No unassigned shards.
• Alerts show clear or no issues on indices.

Verify disk and storage utilization

Ensure disk free space and usage metrics are visible for each node.

Steps:

1. Check disk free space shown per node in the Node Metrics panel.
2. Confirm reported disk free space aligns with expectations.

Expected Result:

• Disk free space values displayed for all nodes.
• No fields marked as N/A for disk metrics.
