Exploring a Filer

Foglight for Storage Management supports NetApp filers. NetApp uses the word aggregate instead of pool, but the metrics collected for aggregates and pools are similar. In some filer views, in particular the views on the LUNs tab and Disks tabs, the word pool may be displayed instead of aggregate, but in this context it refers to aggregates.

The Storage Explorer’s Filer dashboard contains information about the selected filer and its child components. The data displayed reflects values for the selected time range. This walkthrough describes the contents of each of the tabs and points you to where you can drill down for more details.

To explore a filer:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Explorer.
2
On the navigation panel, under Topology, expand Filers and select a filer.
