Leveraging Performance Data in Network Management
The keys to successfully gathering and using performance data are straightforward:
• Gather appropriate information
• Display it so it can be readily recognized and acted upon Act on it when appropriate
Determining what data to gather with Raritan is easy—our experts have already culled through
the available information and are only presenting the pieces you need. Raritan’s graphical display
of this information is also easy to navigate and understand, yet powerful enough to be customized
