Symptoms

You have an Exalogic system running Exalogic Elastic Cloud Software (EECS) in a virtual configuration and would like to utilize the monitoring capabilities of Enterprise Manager OpsCenter Control (EMOC) available within the Exalogic rack to monitor the disk utilization (or other metrics) of Guest vServers you have created, so that EMOC will raise a notification when the metric exceeds a user defined high watermark.

You have expanded the "Plan Management" accordion panel, expanded the  "Operational Plans" and "Monitoring Policies" child entries and created a clone of the policy "OC - Operating System":

Within the "Threshold Monitoring Rules" section of your new copy of the "OC - Operating System" policy:

You modified the "File System Used Space Percentage" rule to see the following values:

Finally, you then navigated to the "Assets" accordion panel to select the Operating System entry for the Guest vServer of interest and selected the "Apply Monitoring Policy" action to apply your newly cloned "Monitoring Policy" to the desired Guest vServer asset:

Having set the above monitoring policy, if you expand the "Assets" accordion panel, drill down to the same "Operating System" entry and click on the "Monitoring" tab then, within the "Active Monitoring Rules" section you see a "File System Used Space Percentage" rule applied to the vServer which defines the desired values for the "Info", "Warning" and "Critical" thresholds but has a "No" value in the "Active" column.
