1.1.3 Database
Figure 1.3: A typical deployment architecture of eG Enterprise
The eG database is responsible for persistent storage of the measurement results. Separate tables are
maintained for each of the tests being executed by eG agents. Besides the measurement tables, the
database hosts threshold tables for each test. A threshold table indicates the upper and lower ranges
of the threshold values for each measurement.
The database design provides a way to periodically purge old data from the database. The periodicity
with which the data will be purged by the database is configurable by the user.
1.1.4 User Interface
A web-based user interface enables a user to interact with eG Enterprise. The recommended browser
for the eG user interface is Internet Explorer 8.0 and above and Mozilla Firefox 2.0/3.0/3.5. Broadly,
the eG user interface allows a user to first customize the configuration of eG Enterprise (i.e., what
servers and web sites to monitor, how frequently to monitor, what specific tests to run, etc.) and
subsequently to monitor the measurements made by the agents.
To avoid overwhelming users with the variety and amount of results being generated based on
measurements made by the eG agents, the user interface presents the results of the measurements in
a logical and coherent manner. The eG manager’s interpretation of the state of each element of an IT
infrastructure is first displayed before the results of the individual measurements are made available -
e.g., by displaying graphs indicating the change in value of the measurement with time of day. An
