The aim of network monitoring is to understand what is going on with your network and its components. First of all, this involves collecting, storing and processing data from managed network items. This task is partly fulfilled by configuring monitoring system.
Collecting data is only the very first step of monitoring task. The collected data must be processed, i.e. analyzed in order to:
| • | Reveal their root causes |
| • | Understand how they can be fixed |
| • | Make corrective decisions and implement them. |
One of the most significant tasks of this analysis is data visualization. It doesn't mean only building various charts but, more generally, any kind of presenting data in the form convenient to
| • | Understand current situation and trends |
| • | Reveal inner relations between parameters |
| • | Find events of interest. |
AggreGate Network Manager provides a rich set of tools facilitating data visualization and analysis. The below table represent basic AggreGate Network Manager monitoring facilities categorized by type of monitored object and type of monitoring (metric).
