Verifying StorageCollector/Generic SMIS Storage Agents are Collecting Storage Data

To begin, review the Foglight for Storage Management dashboards to verify you are monitoring the devices you want to monitor. You need the IP address of the Foglight for Storage Management Management Server and your user credentials from the person who installed and configured Foglight for Storage Management.

NOTE: This procedure is intended for Foglight for Storage Management users with the roles of Storage Administrator, VMware Administrator, and Hyper-V Administrator.
Expand Storage & SAN.
Click Storage Environment.
Ensure the Monitoring tab is selected.
On the Storage Environment dashboard, click the Administration tab.
TIP: If you do not see the Administration tab, ask your Foglight for Storage Management Administrator to add the role Storage Administrator to your user account.
In the Storage Agents > StorageCollector Agents list, look for the Storage Collector agent that monitors the missing device or device type. When an agent monitors a device type, click the Edit icon to view a list of named devices in the Edit Agent Properties dialog box.
In the Storage Agents > Generic SMIS Storage Agents list, look for the SMIS Storage agent that monitors the missing device or device type. When an agent monitors a device type, click the Edit icon to view a list of named devices in the Edit Agent Properties dialog box.

Collecting Storage Data for Virtualized Devices and Servers

Click the SAN Topology tab.
Click the Inferred tile.
The Inferred tile lists physical hosts that Foglight for Storage Management has inferred based on an analysis of the switch, array, and filer ports it is monitoring (a process called dependency processing). When physical hosts are connected to storage devices, you can drill down on a host and view connections in SAN Topology tabs.

Understanding Metric Data in Charts and Tables

In the Storage & SAN dashboards, charts and tables display metric data. Data is collected by Storage Collector agents, aggregated into collections, and the collections are published to the SAN & Storage dashboards at regular intervals. For more information about storage collection schedules and the type of data collected, see Modifying Data Collection Schedules.

The data displayed in charts and tables represents data for one or more intervals in the selected time range as follows:

Current. The value collected in the last interval in the selected time range. In charts, the last plotted value is the current value.
Period. Aggregated values for the entire selected time range. Period values are often used to provide context for current values.
Historical. Individual values for each collection interval in the selected time period. Historical values are often presented as datapoints in a plot chart or as sparklines to show how metrics changed over the time period.
Latest. Values in the latest collection interval available, irrespective of the selected time range. If data collection is enabled, this value reflects the latest collection. If data collection is disabled, this value represents the last collection made by the agent. Although latest values are tracked, the SAN & Storage dashboards do not display these values.

For indepth information about metrics, see

Values are not available (n/a) under the following circumstances:

The device vendor does not provide the necessary metric. In this case, the text n/p by vendor appears after the metric name in column headings.
A device is offline (reported in the State field).

Modifying and Extending Data Collection

You can modify and extend data collection in the following ways. You may want to make these changes now, or adjust the settings in the future if you find a need.

If not already enabled during installation, collect data about virtualization device-to-SAN relationships and display this information in SAN topology diagrams. Requires a VMware or Hyper-V Performance agent.

Collecting Virtual Storage-to-SAN Relationships

Infer connections from physical hosts to storage and show the connections in topology diagrams.

Inferring Physical-Host-to-Storage Relationships

Change the default collection interval.

Modifying Data Collection Schedules

Modify when rules trigger alarms (change threshold values) and add a list of email addresses to notify when alarms occur.
