Foglight for Storage Management Shared 7.3.0


	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.


	NOTE: The metrics available in the drop down for selection include only the metrics made available by that particular array or filer vendor.

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 time range.

To further investigate the selected LUN, click Explore in the details panel. See Investigating a LUN.

•

Alarm Summary. Displays alarms on LUNs, disks. To investigate further, click an alarm. See Assessing Storage Alarms.

Disks tab

•

Show Disks With...

This view lets you quickly see the top 15 disks with a selected metric, averaged over the selected time period.

•

Selecting the time period “for current” shows the disks with the worst current metric.

•

Selecting the time period “last 30 minutes, last hour, last 4 hours” shows the disks with the worst average values in that time period.


	NOTE: The selected timerange 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.


	NOTE: The metrics available in the drop down for selection include only the metrics made available by that particular array or filer vendor.

Click on a name in the table, and summary details about that item will be displayed in the Details panel below. This panel will display the exact time period of the completed collections in the selected time range

To further investigate the selected disk, click Explore in the details panel. See Investigating a Physical Disk.

•

Alarm Summary. Displays alarms on disks. To investigate further, click an alarm. See Assessing Storage Alarms.

Advanced Find

The tabs for specific entities (like LUNs, Disks, Pools, NASVolumes) quickly identify the Top 15 objects exhibiting the “worst” values for a particular metric. Often, however, there is a need to locate objects by name, or with other characteristics. Use the Advanced Find functionality to locate these items.

Queries can be constructed using a combination of Property conditions and Metric conditions.

Figure 16.

Advanced Find

Using the Property Conditions

Finding Entities by Name

To find entities by name:

Select the desired entity type to search for in the Find drop down.

Type the string to search for in the Name Like field.

Click Perform Query.

•

All items with that string anywhere in their name will be returned.

•

_ is a positional wildcard, that can match a single character. For example, C_D would match decode, but would not match record

•

% is a non-positional wildcard. For example, C%D would match record

Finding Entities with Current Status or Physical State

To find entities with current status or physical state:

Select the desired entity type to search for in the Find drop down.

In Properties, check the status boxes to retrieve entities with that status or state.

Click Perform Query.

For example, This example searches for LUNs whose names include a particular string, and have a non-normal alarm state.

The query will take a short time to execute. When it completes, the Latest Query panel will summarize the query conditions. The Query Result panel will display the LUNs found to match the query conditions. The table header displays the time period used for evaluating the query conditions.

Figure 17. Query Conditions

Using the Metric Conditions

The metric conditions area lets you easily construct a more complex query that can include up to 3 conditions on metrics.

Figure 18.

Metrics conditions

To use the metric conditions:

Period. Refers to the time range on the zonar displayed in the upper right-hand corner. Select the time the query should use for the metric values. When n/a is selected, this condition is ignored.

Metric. This drop down shows the metrics available for this entity type for this vendor.

The third drop down list provides the comparison operator.

Use the fourth field to enter the value to use for the comparison.

Use the fifth drop down to select the units for the value you entered. The units selection will change based on the type of metric selected.

Click the + icon if you want to add another condition. The next condition row will be preceded by a AND/OR selector. A trash can icon will appear to the right of the + icon to let you remove a condition.

Up to 3 conditions can be defined. When the + icon is clicked to display the 3rd condition row, parentheses will be displayed around the first 2 conditions, indicating the order of evaluation.
