How can I delete the data for a derived metric. (4261189)

Question: I created a derived metric scoped to HostStorage, and later deleted the derived metric. The data for the derived metric is still listed under "Configuration | Data" and under the data used to create custom dashboards. The data for the derived metric is not listed under the Data Management dashboard. How can I delete the data for the derived metric?

RESOLUTION:

After you delete the derived metric you also have to remove the property from the topology type.

The following script will allow you to remove a derived metric from a property type.

__________________________________________

def ts = server.TopologyService

def tt = ts.getType("MyType")

def updateTT = ts.beginUpdate(tt)

updateTT.removeProperty("MyDerivedMetric")

tt = ts.endUpdate(updateTT)

For example, I created a derived metric named "ktest_space_available" that was scoped to HostStorage. I deleted the metric and then ran the follow script:

__________________________________________

def ts = server.TopologyService

def tt = ts.getType("HostStorage")

def updateTT = ts.beginUpdate(tt)

updateTT.removeProperty("ktest_space_available")

tt = ts.endUpdate(updateTT)
