Monitoring gWLM from the command line

There are several command-line tools for monitoring gWLM. These commands are added to the path during installation. On HP-UX systems, the commands are in /opt/gwlm/bin/. On Microsoft Windows systems, the commands are in C:\Program Files\HP\Virtual Server Environment\bin\gwlm\ by default. However, a different path might have been selected at installation.

NOTE: You must be logged in as root on HP-UX or into an account that is a member of the Administrators group on Windows to run the commands below.

•gwlm monitor

The gwlm command, available only on a CMS, has a monitor subcommand that displays policy, workload, and SRD statistics.

•gwlmreport

This command, available only on a CMS, provides various types of reports: topborrowers, resourceaudit, abnormalutil, and extract (which provides data in comma-separated values for use in other tools). It also provides an ovpafeed option that extracts data for use with OpenView Performance Agent via data source integration (DSI). In addition, it can generate a config report showing the history of configuration changes.

•gwlmstatus

The gwlmstatus command, available only on managed nodes, displays status information for a managed node's agent and SRD. The information displayed includes:

◦

◦

◦

◦

◦

◦

◦

Whether gwlmagent is running

The version of the installed gwlmagent

The SRD to which the current node belongs (if a member of a deployed SRD)

Master node of the deployed SRD

Whether hosts in the SRD are nonresponsive

Whether the host's SRD is the most recently deployed SRD on the CMS (This knowledge can be useful in determining failed deployments.)

Whether any hosts are unable to rejoin the SRD

For more information, see gwlm(1M), gwlmreport(1M), or gwlmstatus(1M).

Message logs

For messages about gWLM’s ongoing operations, gWLM logs error and informational messages, as well as statistics, to one of several log files:

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.
