The metriccurrent object contains observable metrics as of the current time; in other words, it stores
information about each metric as of the time the object is queried. Using the same CL_CPUT metric provided above,
run the following command to display your current storage cell CPU utilization:

CellCLI> list metriccurrent CL_CPUT
CL_CPUT cm01cel01 0.4 %
CellCLI>

We see the current CPU utilization of our storage cell is 0.4%. Next, add the detail condition to your list
command to display each metriccurrent attribute:

CellCLI> list metriccurrent CL_CPUT detail
name: CL_CPUT
alertState: normal
collectionTime: 2012-10-25T00:15:01-04:00
metricObjectName: cm01cel01
metricType: Instantaneous
metricValue: 0.9 %
objectType: CELL
CellCLI>

The detailed output shows some additional attributes:

•

alertState is the current alert status of the metric; valid values include normal, warning,
and critical.

•

collectionTime is the time at which the metric was collected.

•

metricValue represents the value of the metric; in the previous case, it displays 0.9%.

•

metricType represents the unit, or scope, upon which the metric's metricValue is based. Valid
values for metricType include Instantaneous (typically presented as a percentage or raw data
value), Cumulative , Rate (units per time interval), or Transition .

•

metricObjectName represents the specific object to which the metric is scoped; for example,
for each CELL objectType , the metricObjectName will be the name of the storage cell.

objectType represents the type of the metric.
To illustrate the different types of CellCLI output, use the following list metriccurrent command to display
current metrics for the CELL objectType :

•

CellCLI> list metriccurrent where objectType='CELL' attributes -
> name,metricObjectName,metricValue,metricType
CL_BBU_CHARGE cm01cel01 91.0 % Instantaneous
CL_BBU_TEMP cm01cel01 41.0 C Instantaneous
CL_CPUT cm01cel01 0.2 % Instantaneous
... Additional Instaneous metrics omitted
