lssystemstats
Use the lssystemstats command to display the most recent values of all node canister statistics in a clustered system (system), or to display a history of values for a given subset of available statistics across all node canisters in a system. This command also can be used to display a history of values for a given subset of available statistics.
Syntax
>>- lssystemstats -- --+----------+-- --------------------------> '- -nohdr -' >--+------------------------+-- --------------------------------> '- -delim -- delimiter -' >--+------------------------------------+-- --------------------> '- -filtervalue -- attribute=value -' >--+-----------------+-- --+----------------------+-- --------->< '- -filtervalue? -' '- -history stat_list -'
Parameters
- -nohdr
- (Optional) By default, headings are displayed for each column of data in a concise style view,
and for each item of data in a detailed style view. The -nohdr parameter
suppresses the display of these headings.Note: If there is no data to be displayed, headings are not displayed.
- -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 possible 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 one-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.
- -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. Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcards:
- The wildcard character is the asterisk (*).
- The command can contain a maximum of one wildcard.
- When you use a wildcard, enclose the filter entry within double
quotation marks (""):
lssystemstats -filtervalue stat_name="io*"
- -filtervalue?
- (Optional) Displays the valid filter attributes for the -filtervalue attribute=value parameter:
- stat_name
- -history stat_list
- Provides the most recent node canister statistical values, specific node canister statistical values, or historical data for any node canister.
Description
The statistical values are
determined using samples received from each .
Note: Values are rounded to the nearest integer when appropriate
(for example, between one and ninety-nine when considering percentages).
Table 1 provides
the attribute values that can be displayed as output view data.
Attribute | Value |
---|---|
stat_current | The current value of the statistic field. |
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. |
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. |
Remember: Filtering is supported
on the stat_name field using the concise view.
