Location

Windows: C:\Program Files\HP\Virtual Server

Environment\logs\gwlm.log.0

gwlm command

HP-UX: /var/opt/gwlm/gwlmcommand.log.0

Windows: C:\Program Files\HP\Virtual Server

Environment\logs\gwlmcommand.log.0

NOTE: On systems running Windows, log files are in C:\Program Files\HP\Virtual Server Environment\logs\ by default. However, a different path might have been selected at installation.

The name of the current log always ends in .log.0. Once this file grows to a certain size, it is moved to a filename ending in .log.1 and a new .log.0 file is started. If a .log.1 file already exists, it is renamed .log.2. If a .log.2 file already exists, it is overwritten.

By default, the log file size is limited to 20 Mbytes and the number of log files is limited to 3. You can change these defaults using the following properties:

com.hp.gwlm.util.Log.logFileSize = 20

com.hp.gwlm.util.Log.logNFiles = 3

For the gwlmagent log, change the values of these properties in /etc/opt/gwlm/conf/ gwlmagent.properties. For all the other log files, change the values in /etc/opt/gwlm/ conf/gwlmcms.properties on HP-UX and in C:\Program Files\HP\Virtual Server Environment\conf\gwlmcms.properties on Windows. (The given Windows path is the default; however, a different path might have been selected at installation.)

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.
