Get node diagnostics
Get diagnostics from a specific cluster node.
NoteThis API call is different from most others, in that on success, it returns a binary download, rather than JSON formatted output. JSON formatted errors are returned in the same way as other API calls.
HTTP request syntax (URI)
GET <base_URI>/v8/storage/nodes/{nodeId}/diagnostics
Parameters
| Name | Type | Required | Values | Description |
| nodeId | URI_PARAM | Y | string/number | Specifies either a node object ID or an HNAS storage cluster node ID. |
Return codes
| Code | Data | Description |
| 200 | Diagnostic attachment | Diagnostic file retrieved successfully. |
| 400 | Error Message | Missing or invalid request contents. |
| 404 | Error Message | Requested resource not found. |
| 500 | Error message | Error associated with the storage system. |
Any HTTP status code other than 200 indicates that the API did not complete successfully.
