Exploring a Fabric

The Storage Explorer’s Fabric dashboard contains information about the selected fabric and its switches as well as all ports used by the switches in the fabric. 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 fabric:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Explorer.
2
On the navigation panel, under Topology, expand Fabrics and select a fabric.
The Fabric dashboard opens with details for the selected fabric.
 
* 
TIP: You can also open this dashboard from the Storage Environment dashboard by selecting a fabric and clicking View in Explorer.

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.
The Filer dashboard opens with details for the selected filer.
 
* 
TIP: You can also open this dashboard from the Storage Environment dashboard by selecting a filer and clicking View in Explorer.

Selecting the time period “for current” shows the NASVolumes with the worst current metric.
Selecting the time period “last 30 minutes, last hour, last 4 hours” shows the NASVolumes with the worst average values in that time period.
* 
NOTE: The selected time range looks at the average of values from collections that completed between the time at the end of the zonar, and the selected period before that.
The bars in the Average column show the values of the other items' metric relative to the first (highest) item.
Click on a name in the table, and summary details about that item will be displayed in details panel below. This panel will display the exact time period of the completed collections in the selected timerange.
To further investigate the selected item, click Explore in the details panel. See Investigating a NASVolume.
