very few critical metrics requiring a fast notification time. Otherwise, you would be introducing significant overhead
on the agent and the rest of the EM framework to process and store a excessive amount of data. It's OK to use a
1-minute collection interval during testing and development (as in this example) to avoid waiting too long for the
metric history to appear. On the Adapter tab, copy the SQL text from Listing 10-1 into the SQL Query field in the Basic
Properties section. You won't be using any advanced properties or uploading files for this example.
