Before you begin

Ensure that Foglight for Infrastructure is installed on the Management Server. For installation instructions, see the Foglight for Infrastructure Release Notes.

•
To monitor PowerVM® servers, you need a running instance of the PowerVM HMC Agent. This agent is provided with Foglight for Infrastructure.
•
Collecting OS-level data from hosts in your PowerVM environment requires running instances of Foglight for Infrastructure Windows or Unix agents. These agents are also provided with Foglight for Infrastructure.

Introducing the PowerVM infrastructure

When you deploy Foglight™ for PowerVM and set up the monitoring agents for data collection, the Infrastructure Environment dashboard enables you to review the performance of your environment at a glance. To ensure consistent application performance, use this dashboard to find out more details about specific components, and to look for potential performance degradation indicators, such as high processor loads or low network utilization.

Foglight for PowerVM focuses on the following components in your monitored PowerVM® environment:

•
HMC (Hardware Management Console) manages a groups of PowerVM servers that are running in your integrated environment.
•
Managed Server is a collection of physical components managed by the PowerVM Hypervisor software layer. PowerVM Hypervisor divides physical system resources into isolated logical partitions. An HMC typically includes multiple logical partitions.
•
Partition encapsulates an operating system and application components that are running in a PowerVM Hypervisor. It has a dedicated share of the system’s physical resources.
•
VIOS provides a mechanism that enables logical partitions to share physical resources of a managed PowerVM server.

Managing PowerVM HMC agents

Foglight™ for PowerVM relies on PowerVM HMC Agents to collect data from the monitored PowerVM® infrastructure. Foglight for Infrastructure features are provided with Foglight for Infrastructure.

When you install Foglight for Infrastructure, you can create PowerVM HMC Agents to collect performance information about your PowerVM environment. To connect to the monitored PowerVM system, the monitoring agents must have sufficient permissions. For complete information, see the following sections:

•
Configuring HMC user accounts
•
Configuring PowerVM HMC agent credentials
•
Creating PowerVM HMC agents
•
Reviewing and editing PowerVM HMC agent properties

Configuring HMC user accounts

To connect to the monitored Hardware Management Console (HMC), each PowerVM HMC Agent requires a valid user account. An HMC account requires a user name and password to connect to the HMC. You specify this information by creating a Foglight credential of the User Name and Password type (see Configuring PowerVM HMC agent credentials).

Each HMC user account has a role that grants access to specific parts of the HMC. Each PowerVM HMC Agent instance must be associated with a valid HMC account. To ensure that the HMC account provides access to all elements of your monitored environment, including Virtual I/O Servers (VIOS), the account must be granted a role with sufficient permissions.

To create an HMC role for the PowerVM HMC Agent:
1
Create a custom HMC role based on the hmcoperator role.
2
Remove any unnecessary permissions from the newly created role, as required. For example, your organization may require that such role should grant permissions for changing resources or restarting hosts.
3
Ensure that the Issue virtual I/O server command permission is granted to the newly created HMC role. This permission enables the agent to issue the viosvrcmd command. Removing it causes the HSCL350B error, indicating that the user account does not have appropriate permissions. For more information about this error, visit:

For more information about HMC roles, see your HMC documentation.
