Glossary
SNMP – Simple Network Management Protocol. A set of rules
governing the management of networks and the monitoring of
network devices and functions. See also MIB.
Solaris – A UNIX-based operating environment developed by Sun
Microsystems. Originally developed to run on Sun’s SPARC
workstations, Solaris now runs on many workstations from other
vendors.
SSL – Secure Sockets Layer. Netscape’s public key encryption and
authentication software. Both Netscape Navigator and Internet
Explorer support SSL, and many web sites use the protocol to obtain
confidential user information, such as credit card numbers. By
convention, web pages that require an SSL connection start with
“https” instead of “http.” OneSight supports SSL when specifying
URLs for URL monitors. SSL can also be used in combination with a
proxy server. Up to 128-bit encryption is supported if enabled on
the browser for the Empirix OneSight server.
Threshold – A measurement set for a metric that defines what is and
is not acceptable performance for that metric.
Trap – To intercept an action or event before it occurs, usually in
order to do something else. See also SNMP.
Warning state – A OneSight indicator of the state of a metric,
monitor, or monitor group. Web components that are in a Warning
state may require your attention. In OneSight, a Warning state is
represented by a yellow triangle. When you configure monitors, you
define the performance criteria that you want to track and the
conditions under which you want to receive an alert. In response to
an alert, OneSight can either trigger an action plan, change a
monitor’s health, or in some cases, do both.
Web component – Any part of your web site that you would like to
monitor. This can include devices such as your NT server or UNIX
web farm, the database that supports your web site transactions, the
web server software, or mission-critical URLs within your web site.
