| 36 | +## Verify Cluster Health Summary |
| 37 | + |
| 38 | +**Description:** |
| 39 | +Confirm cluster health status, total nodes, shards, indices, and document count are displayed and accurate. |
| 40 | + |
| 41 | +**Steps:** |
| 42 | +1. Locate the **Cluster Health Summary** panel. |
| 43 | +2. Validate: |
| 44 | + - Cluster status (Green, Yellow, Red) — expect Green for healthy cluster. |
| 45 | + - Number of nodes. |
| 46 | + - Number of indices. |
| 47 | + - Total shards and unassigned shards. |
| 48 | + - Total documents. |
| 49 | + - Data size. |
| 50 | + |
| 51 | +<details> |
| 52 | +<summary><strong>Expected Result</strong></summary> |
| 53 | + |
| 54 | +- Cluster health is **Green (Healthy)**. |
| 55 | +- Nodes, shards, indices, and documents display current, non-zero values. |
| 56 | +- No unassigned shards. |
| 57 | +- Data size is displayed accurately. |

| 65 | +## Verify Node Metrics |
| 66 | + |
| 67 | +**Description:** |
| 68 | +Ensure node-level metrics such as CPU usage, JVM heap usage, and disk space are reported per node. |
| 69 | + |
| 70 | +**Steps:** |
| 71 | +1. Open the **Node Metrics** or **Elasticsearch Nodes** panel. |
| 72 | +2. Confirm each node shows: |
| 73 | + - Status (Online). |
| 74 | + - CPU usage (percentage). |
| 75 | + - JVM heap usage (percentage). |
| 76 | + - Disk free space. |
| 77 | + - Load Average (may be unavailable, verify if data present). |
| 78 | + |
| 79 | +<details> |
| 80 | +<summary><strong>Expected Result</strong></summary> |
| 81 | + |
| 82 | +- All nodes listed. |
| 83 | +- CPU, JVM heap %, and disk free space values present. |
| 84 | +- Load average may show as N/A if unsupported but should be monitored for future inclusion. |

| 92 | +## Verify Index Statistics |
| 93 | + |
| 94 | +**Description:** |
| 95 | +Validate index-level metrics including document counts, data size, indexing rate, and search rate. |
| 96 | + |
| 97 | +**Steps:** |
| 98 | +1. Open the **Indices** panel. |
| 99 | +2. Review per-index data such as: |
| 100 | + - Document count. |
| 101 | + - Data size. |
| 102 | + - Indexing rate (docs per second). |
| 103 | + - Search rate (queries per second). |
| 104 | + - Unassigned shards (should be zero). |
| 105 | +3. Check for any alerts or warnings on indices. |
| 106 | + |
| 107 | +<details> |
| 108 | +<summary><strong>Expected Result</strong></summary> |
| 109 | + |
| 110 | +- Per-index document counts and data sizes are populated. |
| 111 | +- Indexing and search rates update regularly. |
| 112 | +- No unassigned shards. |
| 113 | +- Alerts show clear or no issues on indices. |
