Optimize Global Workload Manager (gWLM) View Summaries

gWLM allows you to easily monitor SRDs and their workloads in real-time by selecting the View Summaries menu item.

This help page covers the following topics:

» Summary of SRDs table

» Individual SRD detail table

» Status information: Critical, Major, Minor, and Normal

Sort the rows in a table by selecting the column heading that you would like to sort by.


	Summary of SRDs table

The main table in the View Summaries window includes the following columns:

Column	Description
Shared Resource Domain	Name of an SRD Select an SRD to view data on its workloads. Scroll down to see this data.
Type	The type of compartment managed in the SRD: npar, vpar, pset, or fss group
Mode	Managed / Advisory
Size	The amount of a resource a compartment actually has For CPU, size may differ from the allocation when gWLM is deployed in advisory mode.
Utilization	The percentage resulting from dividing the amount of a resource consumed in the SRD by the amount of the resource available in the SRD
Last Update	The time at which the data being presented was gathered
Hostnames	Hosts with workloads in the SRD


	Individual SRD detail table

When you select an SRD in the first table on the View Summaries window, a second table appears. This table shows the following data for the workloads in the SRD:

Column	Description
Workload	Name of a workload Select a workload to go to the View Real-time Reports window, where you can graph workload data.
Policy	Name of the policy associated with the workload Select a policy to go to the View Real-time Reports window, where you can graph policy data.
Policy Status	Status showing how well the policy is being met For information on the various status icons, see the table below.
Request	The amount of a resource the policy is requesting for the workload
Allocation	The amount of a resource, such as CPU, that gWLM sets aside for a compartment after arbitrating resource requests from the policies for all the compartments In managed mode, gWLM makes an allocation available to a compartment. In advisory mode, however, gWLM simply reports what the allocation would be--without actually affecting resource allocations on a system. The amount allocated may be restricted by the minimum and maximum number of CPUs you specify for compartments when creating them using npar, vpar, or pset commands.
Size	The amount of a resource a compartment actually has For CPU, size may differ from the allocation when gWLM is deployed in advisory mode.
Utilization	The percentage resulting from dividing a workload's consumption of a resource by its allocation of that resource. For example, assume a workload has an allocation of 5 CPUs. If the workload is consuming 4.5 CPUs, its utilization percentage is 4.5/5, or 90%.
Hostname	Host where the workload is running


	Status information: Critical, Major, Minor, and Normal

This section explains what to do for a given status.

Status	Possible cause	Action
Critical	A daemon is not running Network issues A managed node is down	Ensure gwlmagent is running on each managed node Check the network Ensure each managed node is up
Major	An SRD is in managed mode and has one or more of the following conditions: Request > Size Allocation > Size Request > Allocation	Request > Size or Request > Allocation: There are not enough resources to meet the request. For a utilization policy, this means the policy is not being satisfied. For an OwnBorrow policy, the policy is most likely being satisfied because the workload is getting what it owns (the allocation); however, the request for additional resources (request for borrowing) is not being met. Allocation > Size: The CPU count has been decreased manually, outside gWLM. If this status persists beyond one interval, contact HP support.
Minor	An SRD is in advisory mode and has one or more of the following conditions: Request > Size Allocation > Size	In both cases: If there are excess resources that can be allocated to the workload, using gWLM in managed mode would be beneficial.
Normal	Data is current and policies are being satisfied	No action needed
