Connectivity and I/O Performance Monitoring

Foglight for Storage Management provides comprehensive topology views which detail all I/O paths and components on each I/O path from VMs down to their assigned physical storage devices. These views assist in determining where actual performance or connectivity problems are occurring during I/O requests, something which is not possible using traditional virtual infrastructure management tools. For more information, see Assessing Connectivity and I/O Performance.

Navigating Foglight for Storage Management

Foglight for Storage Management is built on the Foglight platform. The following diagram and table introduce the common Foglight for Storage Management screen elements that are used in Foglight for Storage Management dashboards. If you need more information about how to use these elements, open the online help and navigate to Foglight User Help > Getting Started > Working with Dashboards.

Figure 4. Navigating Foglight for Storage Management.

 
 
Table 1. Screen Elements
Screen Element
Description
Navigation Panel

Contains a menu of all the dashboards that you can access based on your role. Select a dashboard to view in the display area. The panel operates like a drawer and can be open or closed using the arrow.

Display Area

Displays the contents of the selected dashboard.

Action Panel

Provides the following functions:

•
Lists the actions that you can perform on the current dashboard.
•
Lists the views and data that you can add to a new dashboard or report.
•
Provides access to context-sensitive help and the online help system.

The panel operates like a drawer and can be open or closed.

Breadcrumbs

Displays the path of dashboards you navigated to get to the current dashboard. Click a name in the path to return to that dashboard.

NOTE: The browser Back button is disabled. Use the breadcrumbs to return to the previous screen.
Time Range

Controls the time period for the data displayed in the dashboard and any drill-down views you access. The default is the last four hours. Click the text to open the time range popup and set the range.

Sparkline

Shows the trend of a metric in a small space. The value beside the sparkline is the current value for the metric in the selected time range. When used in a table, sparklines provide an easy way to compare spikes or other trends in a group of metrics. Click a sparkline to plot all data points for the time period on a graph.

NOTE: If the last collection failed for any reason, the sparkline value is n/a.
Status Icons

Displays the status of a storage resource. For more information, see Understanding Status, Alarms, and Rules in Foglight for Storage Management.

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.
To log in and confirm the list of monitored devices:
1
Open a supported browser. For a list of supported browsers, see the System Requirements Guide.
2
In the navigation bar, type the IP address followed by the port number 8080. For example:
http://<Foglight for Storage Management_Management_Server_IP_Address>:8080
3
Log in to Foglight for Storage Management using your user credentials.
4
On the navigation panel, expand Dashboards.
These menu items are of particular interest for monitoring storage performance: Storage & SAN, VMware, Hyper-V and Infrastructure.
5
Expand Storage & SAN.
The following menu items are available:
•
Storage Capacity — Monitor your storage capacity by device type.
•
Storage Environment — Monitor storage devices in your storage environment.
•
Storage Explorer — Find and examine any storage device in your storage environment.
6
Click Storage Environment.
7
Ensure the Monitoring tab is selected.
8
Click the top half of each active tile and review the list of devices in the quick view.
9
If you do not see a storage device that you think should be monitored, review the list of configured Storage Collector agents.
a
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.
b
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.
Or
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.
c
If a StorageCollector agent or Generic SMIS Storage agent does not exist for a device, or if the agent exists but it is disabled or its data collection is turned off, contact your Foglight for Storage Management Administrator. For instructions about agent tasks, see the Foglight for Storage Management Installation Guide.
10
Go to the dashboard for the storage device or switch and ensure that both performance and topology information have been submitted recently.

Collecting Storage Data for Virtualized Devices and Servers

To collect storage data for virtualized devices and servers:
1
On the navigation panel, expand the dashboard menu for your virtualization software. For example, either VMware or Hyper-V.
 
* 
TIP: If you do not see the VMware or Hyper-V menu, ask your Foglight for Storage Management Administrator to add the appropriate administrator role to your user account.
In a Foglight for Storage Management installation without Foglight for Storage Management for Virtualization EE, the following menu items are available when you expand VMware or Hyper-V (additional menu items are available with Foglight for Storage Management for Virtualization EE):
•
Agent Administration — Create, edit, and delete the Performance agents to monitor the virtual environment.
•
Explorer — Monitor entities in your virtual environment.
2
To verify the virtualization agents:
a
Click the Hyper-V or VMware Explorer.
The Explorer opens a Virtual Infrastructure Topology tree—displayed in the navigation panel below the list of Dashboards—that contains branches for each monitored vCenter or Hyper-V server. For detailed information about the dashboards available through this tool, see the Managing Virtualized Environments User and Reference Guide.
b
If the Virtual Infrastructure Topology list is empty, your Foglight for Storage Management Administrator needs to create a Performance agent to monitor at least one vCenter or Hyper-V server. For instructions, see the Foglight for Storage Management Installation Guide.
c
If the list is not empty, expand the tree and select a virtualization host or server.
d
Click the SAN Topology tab.
e
Verify that you can see the storage-side of the virtual infrastructure, identified by the icons that are circled in the following diagram. If these elements are missing, the Performance agent monitoring this host is not collecting the data necessary to make connections to storage and SAN data. To enable storage data collection, see Collecting Virtual Storage-to-SAN Relationships.
After you finish with Performance agents, review monitored hosts.
3
On the navigation panel, click Infrastructure.
a
In the Select a Service box, select All Hosts.
The tiles organize physical hosts by their operating system.
b
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.
c
If the Inferred tile does not show any inferred hosts, you may want to enable dependency processing to begin collecting the names of inferred hosts. For more information, see Inferring Physical-Host-to-Storage Relationships.
You have finished verifying that agents are collecting data.
