View historical metrics settings

View historical metrics settings. The default output appears in a tabular format.

NOTE:Use the show action command to change the output format.

Format

/metrics/value/hist -path <value> show -interval { 60 | 300 | 3600 | 14400 }[ -from <value> ] [ -to <value>] [ -count <value> ][ -flat ][ -summary ]

Object qualifier

QualifierDescription
-pathSpecify a comma-separated list of metric paths.
NOTE: When typing metric paths, replace . with \., , with \, and \ with \\ in the object names.
-intervalSpecify an interval for the metric values. Default interval is seconds.
-fromSpecify the start of the query period. The format is: YYYY-MM-DD HH:MM:SS or YYYY-MM-DDTHH:MM:SS, where:
  • YYYY — Year
  • MM — Month
  • DD — Day
  • T — Time delimiter
  • HH — Hour
  • MM — Minute
  • SS — Second
NOTE:Ensure that the value is a time in the past. You can choose to specify just the date (in the YYYY-MM-DD format) or the time (in the HH:MM:SS format). If you do not specify the time, the system automatically uses 00:00:00. If you choose to not specify the date, the current system date is used.
-toSpecify the end of the query period. The format is: YYYY-MM-DD HH:MM:SS or YYYY-MM-DDTHH:MM:SS, where:
  • YYYY — Year
  • MM — Month
  • DD — Day
  • T — Time delimiter
  • HH — Hour
  • MM — Minute
  • SS — Second
NOTE:Ensure that the value is a time in the past. You can choose to specify just the date (in the YYYY-MM-DD format) or the time (in the HH:MM:SS format). If you do not specify the time, the system automatically uses 00:00:00. If you choose to not specify the date, the current system date is used.
-countSpecify the number of samples to display. A sample is a set of metric values related to a single timestamp. Valid values are numbers greater than or equal to one.
-flatDisplays the member values for grouped metrics.
-summaryDisplays the maximum, minimum, and average value for each metric.
NOTE:The -from and -to qualifiers take precedence over the -count qualifier. In the example below, only 7 samples exist between the from and to dates. Although the value for the -count qualifier is set to 10, only 7 values appear. If the -from and -to qualifiers are not specified, the output will include 10 samples.

Examples of output with different combinations of the -from, -to, and -count qualifiers

The following table illustrates the output that appears with combinations of the -from, -to, and -count qualifiers. It assumes that the current time is 2012-09-21 12:30:00.

Qualifier CombinationOutput
-from <future date/time>Example: -from “2012-09-21 12:31:00”

Result: This results in an error because the time for the -from qualifier is specified in the future.

-from <current date/time or date/time in the past>

-to <future date/time>

Example: -from “2012-09-01 00:00:00” -to “2012-09-21 12:31:00”

Result: This results in an error because the time for the -to qualifier is specified in the future.

-from <date/time in the past> -count <value>Example: -from “2012-09-20 01:02:00” -count 100

Result: The result includes 100 samples from “2012-09-20 01:02:00”. If there are less than 100 samples available, the result lists all samples from the specified time to the current time.

-from <date/time in the past>

-to <current date/time or date/time in the past>

-count <value>

Example: -from “2012-09-20 01:02:00” -to “20-09-20 12:00:00” -count 100

Result: The result includes 100 samples within the specified time period. If there are less than 100 samples available, the result lists all samples within the time period.

-to <current date/time or date/time in the past>

-count <value>

Example: -to “20-09-20 12:00:00” -count 100

Result: The result includes the latest 100 samples before the specified time. If there are less than 100 samples available, the result lists all samples.

-count <value>Example: -count 100

Result: The result includes the latest 100 samples, or if there are less than 100 samples available, the result lists all samples.

-to <current date/time or date/time in the past>Example: -to “20-09-20 12:00:00”

Result: The result includes all samples from the timestamp of the earliest sample to the specified time.

-from, -to, and -count are not specified.Result: The result includes the latest 100 samples, or if there are less than 100 samples available, the result lists all samples. This is equivalent to “-count 100”.
