Global Workload Manager (gWLM)
View Historical Reports
gWLM can generate historical reports for your workloads and policies.
In historical graphs, each data point is the average of the five
preceding minutes of values. (You can change the number of minutes used
by editing the property com.hp.gwlm.node.samples in the file
/etc/opt/gwlm/gwlmcms.properties on your gWLM CMS. Re-deploy an SRD
for it to use the updated property value.)
From the View Historical Reports window,
you can:
Limit the items displayed by using the
Filter by feature above the table.
| | Modes |
You will see one of the following mode indicators directly above the
graphs:
These indicators specify whether the data being graphed reflects an SRD
that was deployed in advisory mode, managed mode, or a mix of the two
modes.
| | View Workload Detail |
Select a workload in the table then the [View Workload
Detail] button to see:
This window also shows a table listing all the policies that have been
associated with the workload. The policy you chose in the previous window
is selected.
To see the workload under the influence of another policy:
Select a different policy in the table
Select the [Show/Refresh Workload Graph] button
Select a date range using the fields below the graph. By default, these
fields are filled using dates for the last week the given policy and
workload were associated. If the association is still active, the dates for
the last week are used--assuming the association has existed a week. For
associations shorter than one week, the dates start with the day the
association was created and end with the current day.
Workload Utilization graph
The Workload Utilization graph shows what the workload's allocation was, as
well as its utilization of that allocation. (How quickly the graph is drawn
depends on the amount of historical data available for the time range being
displayed.)
The graph labels each axis as follows:
Labeling the two vertical axes differently allows for the presentation of
additional data.
The Workload Utilization graph shows the following items:
| | View Policy Detail |
Select a policy in the table then the [View Policy
Detail] button to see:
How quickly the graph is drawn depends on the amount of historical data
available for the time range being displayed.
The window also shows a table listing all the workloads that have been
associated with the policy. The workload you chose in the previous window
is selected.
To see how the policy affected other workloads:
Select a different workload in the table
Select the [Show/Refresh Policy Affect Graph] button
Select a date range using the fields below the graph. By default, these
fields are filled using dates for the last week the given policy and
workload were associated. If the association is still active, the dates for
the last week are used--assuming the association has existed a week. For
associations shorter than one week, the dates start with the day the
association was created and end with the current day.
The graph resizes to show the available data in the most detail. If you
have just started collecting data, the graph may show only a few
hours--although the data range is a whole week.
Policy Request and Workload Allocation graph
This graph shows what allocation the policy requested for the
workload's compartment and the allocation the compartment actually got after
gWLM arbitrated the requests from all the policies.
The graph labels each axis as follows:
You can graph each of the following items by selecting its checkbox below
the graph:
Policy Input and Resulting Request graph
The Policy Input and Resulting Request graph shows the input to a policy (a
"measured" value and a "target" value) and the resource request that was
generated based on that input.
The graph labels each axis as follows:
Labeling the two vertical axes differently allows for the presentation of
additional data.
You can graph each of the following items by selecting its checkbox below
the graph:
* Utilization values are graphed for
utilization policies and OwnBorrow policies. ** Size values are graphed for fixed policies. *** Reading and Target values are graphed for custom policies.
