one. A profile can be applied to a single web component or to
multiple web components. For example, if you have a web farm of
multiple NT servers, you can define the same performance criteria
for all of them in a single profile. When you apply a profile to a
specific machine, you create a profile monitor. See also Metric and
Profile monitor.
Profile monitor – A monitor that uses a number of metrics to test the
performance of various critical functions carried out by a back-end
web component. To create a profile monitor, you apply a profile to
a web component such as an IIS server, an Oracle database, an NT
operating system, or a UNIX operating system on a specific
machine. As you add a profile monitor, you will need to identify the
system and enter system-specific information to describe its
properties. A profile monitor can be applied to more than one web
component of the same type and it will use the same set of
performance criteria for each of those web components. In contrast,
a dedicated monitor only applies to one web component. When
adding a dedicated monitor, you always define unique performance
criteria for the monitor. See also Dedicated monitor, Metric, and
Profile.
Proxy server – A server that sits between a client application (such
as a web browser) and a real server. It intercepts all requests to the
real server to see if it can fulfill the requests itself. If not, it
forwards the request to the real server.
Remote agent – See OneSight Remote Agent.
Service – Work performed (or offered) by a server. This may mean
simply serving simple requests for data to be sent or stored (as with
file servers, email servers, SQL servers, etc.). To see details about
Windows NT and Windows 2000 Services, click Start and select
Settings, then Control Panel. In Control Panel, open Services.
SMTP – Simple Mail Transfer Protocol. A protocol used to
exchange mail between computers.
