Main Spotlight on Sybase ASE Window

The main Spotlight on Sybase ASE window provides a quick and intuitive view of the activity of a Sybase instance.

The Spotlight on Sybase ASE window helps you locate system bottlenecks quickly. Related server statistics are grouped together on panels that are connected by a series of graphical flow and icons. Spotlight on Sybase ASE updates these flows in real time so that you can see how quickly data is moving through the system. The icons change color as their values move through the range of thresholds.

The following graphic shows the main features of the Spotlight on Sybase ASE window.

Alarm Log

The Alarm Log page displays a table of logged alarms for your defined Spotlight connections. When you first open the Alarms Log, the Connection control displays the name of the current connection.

You can:
  • View alarms for a specific connection.
  • Filter the Alarm Log table so that all, some, or none of these alarms are displayed.

HistoryBrowser

An important feature within Spotlight is the ability to display, collect and replay the behavior of a Spotlight connection at a specified point in time such as when an important alarm was raised.

The details shown via the History browser are identical in format to those displayed by Spotlight in its "live" state, so you can view historical data in the same way as you would view a live connection.
