But what constitutes useful work ? We believe that if the server is busy doing the task for which it was bought and
provisioned, then it is performing useful work, if it is busy doing anything else, however important, then it is
performing non-productive work.
For example, a SQL Server doing SQL processing is performing useful work since users and/or applications will
typically access SQL. The same server performing Anti-Virus scanning is not doing useful work since whilst AV
scanning is important, it is not directly serving end users.
NightWatchman Server Edition uses cutting edge technology to analyze the actual workload of a server at the
application level, and will show at a glance whether or not the server is performing useful work.
For example, below is an example of a well utilized server:
As you can see from the legend, the orange section represents the total Watts of power the server is consuming.
This server is currently consuming approximately 200 Watts of power but at peak load could consume up to 400
Watts as denoted by the green and red dotted lines. The blue section represents the calculated useful work the
server is performing. This server is considered well utilized as there is typically more than 50% useful work.
