=over 8
=item B<--exclude-statistics>
(optional) Statistics to exclude from the query. 'Average' can't be excluded.
=item B<--metric>
Metric to query.
=item B<--period>
(optional) The granularity, in seconds, of the returned datapoints. period must be at least 60 seconds and must be a multiple of 60. The default value is 300.
=item B<--start-time>
(optional) The time stamp to use for determining the first datapoint to return. The value specified is inclusive; results include datapoints with the time stamp specified.
exemple: 2014-04-09T23:18:00
=item B<--end-time>
(optional) The time stamp to use for determining the last datapoint to return. The value specified is exclusive; results will include datapoints up to the time stamp specified.
exemple: 2014-04-09T23:18:00
=item B<--statistics>
(optional) The metric statistics to return. For information about specific statistics returned by GetMetricStatistics, go to statistics in the Amazon CloudWatch Developer Guide.
Valid Values: Average | Sum | SampleCount | Maximum | Minimum
Average is the default and always included.
'all' for all statistics values.
=item B<--object>
Name of the object to request (InstanceId for an EC2 instance, for exemple).
=item B<--warning>
(optional) Threshold warning.
=item B<--critical>
(optional) Threshold critical.
