3 Monitoring workloads and gWLM

This chapter describes how to monitor workloads and gWLM.

Monitoring workloads

There are several methods for monitoring workloads, as described below.

High-Level view

To see a high-level view of the performance of your SRDs and workloads:

1.From the System Insight Manager menu bar, select: ToolsHP Matrix OE visualization...

2.Click the Shared Resource Domain tab.

Graphical reports

gWLM provides graphs showing either real-time or historical data through System Insight Manager. For information on interpreting these reports, refer to the online help.

Real-time reports

To view real-time reports:

1.From the System Insight Manager menu bar, select: ToolsHP Matrix OE visualization...

2.Click the Shared Resource Domain tab.

3.Select a workload.

4.From the HP Matrix OE visualization menu bar, select: ReportgWLM Real-time Reports...

Quick link option

In the previous procedure, instead of selecting a workload and using the HP Matrix OE visualization menu bar, you can click the workload's “CPU Utilization” bar graph.

Historical reports

To view historical reports:

1.From the System Insight Manager menu bar, select: ToolsHP Matrix OE visualization...

2.Click the Shared Resource Domain tab.

3.From the HP Matrix OE visualization menu bar, select: ReportgWLM Historical Reports…

Viewing gWLM reports in monitor-Only mode

gWLM allows you to specify users who should be allowed only to monitor gWLM reports. These users do not have the ability to change gWLM configurations. To set up a user with monitor-only privileges, refer to the online help topic “Authorizations and Read-only Monitoring.”

HP UX 11i Workload Management (gWLM/WLM) Software Monitoring workloads and gWLM, Viewing gWLM reports in monitor-Only mode

UX 11i Workload Management (gWLM/WLM) Software specifications

HP-UX 11i Workload Management (gWLM/WLM) software is an integral component of HP's premier UNIX operating system, designed to enhance system performance and resource management across diverse workloads. This advanced tool allows system administrators to monitor, control, and allocate resources effectively to achieve optimal performance, reliability, and service levels in enterprise environments.

One of the main features of gWLM/WLM is its ability to classify workloads and manage them according to specific policies set by the administrator. By using service level objectives (SLOs), administrators can define the performance criteria for various applications and workloads. gWLM continuously tracks these workloads, ensuring that they adhere to the defined SLOs, thus maintaining a high level of application performance.

The software employs resource pools, which segment resources such as CPU, memory, and I/O bandwidth among different workloads based on predefined priorities. This capability ensures that critical applications receive the resources they require, even during peak usage periods, thereby preventing resource starvation that could lead to system slowdowns or crashes.

Another significant characteristic of gWLM/WLM is its real-time monitoring and reporting capabilities. The software provides detailed insights into resource utilization, workload performance, and system health. Administrators can access this information through a user-friendly interface, allowing for informed decision-making and proactive management.

Integration with HP Serviceguard adds another layer of functionality, enabling high availability for critical applications. gWLM can orchestrate workload migration to ensure that service levels are maintained, even in the event of hardware failures or resource contention.

The technology behind gWLM/WLM is built on advanced algorithms that leverage historical data and predictive modeling to optimize resource allocation dynamically. This means that as workloads change, the system can automatically adjust resource distribution to meet performance targets without the need for constant manual intervention.

gWLM also supports integration with various enterprise management tools, enabling administrators to implement comprehensive monitoring and management strategies across the IT infrastructure. The scalability of gWLM allows organizations of all sizes to benefit from its robust workload management features, ensuring that they can adapt to changing demands in their operational environments.

In summary, HP-UX 11i Workload Management software offers a sophisticated solution for optimizing resource utilization, managing workloads effectively, and maintaining high performance in complex enterprise environments. Its comprehensive features and technologies make it an essential tool for any organization seeking to enhance their IT operations.
