The following steps describe how to perform a simple "manual" testing of the Barometer components:
+On the controller:
+You will need update the archive policy rule for gnocchi via the command line.
+The default is low, which means that you only get a metric every
+5 minutes. To do this:
+.. code:: bash
+ $ openstack metric archive-policy rule delete default
+ $ openstack metric archive-policy-rule create -a bool -m '*' default
+Using the ``bool`` archive policy reduces the number of aggregation methods run
+to one (last), and it keeps all metrics at a 1 second interval.
+In order to query this you need to explicitly choose an aggregation method to
+display (by default, ``measures show`` uses mean). You may have to update the
+command for checking the metrics, this is the CLI command:
+.. code:: bash
+ $ watch –n2 –d openstack metric measures show --aggregation last <metric_id>
+More on testing and displaying metrics is shown below.
+On the compute:
1. Connect to any compute node and ensure that the collectd service is running. The log file
``collectd.log`` should contain no errors and should indicate that each plugin was successfully
loaded. For example, from the Jump Host:
