Changing the gWLM Resource Allocation Interval

The frequency of gWLM’s changes in the CPU resource allocations is an attribute of the SRDs. Once you create an SRD, you can change how often gWLM adjusts the CPU resource allocations of the workloads in that SRD using either of the methods discussed in the following sections.

Changing the Interval in HP SIM




	NOTE: If you are managing virtual machines, specify a resource allocation interval that is a multiple of the vm_fssagt interval, which defaults to 10 seconds. If you need a resource allocation interval of fewer than 10 seconds, set the interval for the VM agents (using vm_fssagt -i) to the same value as your resource allocation interval.

Using HP SIM, you can set the interval in two places:

When creating an SRD
From the HP SIM menu bar, select:
ToolsVSE Management
Then, click the Shared Resource Domain tab. From the VSE Management menu bar, select:
CreateShared Resource Domain
When editing an SRD
From the HP SIM menu bar, select:
ToolsVSE Management
Then, click the Shared Resource Domain tab. From the VSE Management menu bar, select:
ModifyShared Resource Domain

Changing the Interval on the Command Line

Use the gwlm command and a text editor to change the interval on the command line:

Use gwlm export to get a copy of the SRD’s XML definition from the gWLM configuration repository.

Edit the “interval” attribute, which is in seconds.




	NOTE: If you are managing virtual machines, set the interval attribute value to a multiple of the vm_fssagt interval, which defaults to 10 seconds. If you need a gWLM interval attribute value of fewer than 10 seconds, set the interval for the VM agents (using vm_fssagt -i) to the same value.

Use gwlm import --clobber to place the updated definition in the gWLM configuration repository.
If an SRD of the same name is already deployed, the import operation puts the new interval into effect. Otherwise, the interval is used the next time you deploy the SRD you just defined and imported.
