Question: How can I display the Core Reporting Elements broken out by database

with 3-second granularity?

Answer: The -D option supports monitoring a list of databases. In Figure 2, the

BENCH and DEV databases are being monitored as cluster-wide entities. As such,

the data under the “bench” column represents activity from all of the instances

accessing the “bench” database—in this case, four instances. For example, the last

line of output in Figure 2 shows that during a 3-second period, all instances

accessing the “bench” database performed a total of 2155 synchronous reads and

1374 asynchronous writes.
