lsnodecanisterstats
The lsnodecanisterstats command displays the most recent values of all node canister statistics, and displays all node canister statistics for a particular canister. This command also can be used to display a history of values for a subset of available statistics.
Syntax
Parameters
- -delim delimiter
- (Optional) By default in a concise view, all columns of data are space-separated. The width of
each column is set to the maximum width of each item of data. In a detailed view, each item of data
has its own row, and if the headers are displayed, the data is separated from the header by a space.
The -delim parameter overrides this behavior. Valid input for the
-delim parameter is a 1-byte character. If you enter
-delim :on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter. - -history stat_list
- (Optional) Provides the most recent node canister statistical values, specific canister statistical values, or historical data for any canister.
- nodecanister_id | nodecanister_name
- (Optional) Identifies the node canister for which you want to request statistics.
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.
The following table provides the possible values that are applicable to the values that are
displayed for the stat_name attribute.
