The new CLI is "dfm perf data retrive" not "dfm perf view retrieve". The
syntax for the new cli is as follows:
dfm perf data retrieve help
NAME
retrieve -- This command allows you to extract the counter data
with supported statistical calculations on them.
SYNOPSIS
dfm perf data retrieve { [ -C
perf-counter ... ]
}
[ -m statistical-method
]
DESCRIPTION
This command retrieves performance data for the specified counters and
object instances. These counters and instances can be specified
explicitly
using the -C and -o options or implicitly by specifying the view-name
using -V option.
When the view specified is associated with object types, the object
instance has to be explicitly specified using the -o option. When
the view
specified is associated with object instances, this option is not
mandatory. If -o option is specified in this case, the specified object
instances are considered, ignoring the instances in the view. If
counters are explicitly specified along with the view, the counters
in the view are ignored and the explicitly specified counters are
considered instead.
For finer control on the time, a filter with months, days and time
range with in a day can be specified. Only those time stamps that
satisfy the filter will be shown in the output. On the resulting
output of
counter data, statistical computations like minimum, maximum, mean,
and value_at_percentile can be computed.
Description of options:
-o Object instance for which data is to be retrieved. Multiple object
instances can be specified. Specifying a parent will retrieve data
for all its children.
-C A counter of the form object-name:counter-name (ex.
system:cpu_busy).
Multiple counters can be specified.
-V View Name. A view name can be specified, instead of specifying the
counters and instances explicitly.
-b Start time. Format: "yyyy-mm-dd hh:mm:ss". If this option is not
specified, the start time will be the time of the oldest record.
-e End time. Format: "yyyy-mm-dd hh:mm:ss". If this option is not
specified, the end time will be the time of the newest record.
-d Duration for which data is to be retrieved (in seconds). The time is
calculated going backwards from the current time. When this option
is specified, start-time and or end-time are ignored.
-s Sample rate (in seconds). This interval will be used to consolidate
the output data. The available data will be split into regions as
specified by the sample rate and the last sample in each of those
regions will be displayed. Also used for window calculation for
metrics.
-x Specifies the format to display the output. Possible values are
Legacy and TimeIndexed. Default value is Legacy.
-R If specified, data is rolled-up to the nearest minute. Applicable
only when the output format is TimeIndexed.
-M Filter based on month. Examples: Jan, Feb, etc. Comma separated
multiple values
can be specified.
-D Filter based on day of week. Examples: Mon, Tue, etc. Comma
separated multiple
values can be specified.
-T Filter based on time range in a day. Example: 16.00-21.55. Comma
separated multiple
values can be specified.
-m The statistical computation. Valid values are min, max, mean and
value_at_percentile.
-P For value_at_percentile type of calculation, this contains the
percentile value.
-S For computing on fixed size data, this defines the method to advance
the chunks of data. Valid values are simple, step and rolling.
Default
value is simple. Valid only when a statistical-method is specified.
Simple and step methods are available for all statistical methods.
Rolling is valid only for mean statistical method.
