Description
This command returns a concise list or a detailed view of node canisters that are part of the
clustered system. This table provides the possible values that are applicable to the attributes that
are displayed as data in the output views.
| Attribute | Value |
|---|---|
| nodecanister_id | The ID of the node canister. |
| nodecanister_name | The name of the node canister. |
| stat_current | The current value of the statistic field. The value is accurate up to 3 decimal places (microseconds). |
| stat_list | The system history of the reported statistics. |
| stat_name | The name of the statistic field. |
| stat_peak | The peak value of the statistic field in the last five minutes. The value is accurate up to 3 decimal places (microseconds). |
| stat_peak_time | The time that the peak occurred. |
| sample_time | The time of the sample occurrence. |
| stat_value | The statistical value at the epoch interval. |
Note: Filtering is supported on nodecanister_id,
nodecanister_name, and stat_name fields by
using the concise view.
