Parameters

-delim delimiter
(Optional) Specify a delimiter to separate data in the output.
-nohdr
(Optional) Suppress the headings in the output.
-filtervalue attribute=value
(Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are displayed.

  • Each granularity will show up to 60 samples per stat when used with -history parameter.
-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.
Table 1. Node canister attribute values
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.
