It contains:

■ An empty group called Default Group.

■ The QoS node containing some QoS definitions.

■ The Templates node, containing the templates available.

Preparing the probe

The Ibmvm probe does not monitor anything automatically. Initially, you need to define what to monitor. Perform the following steps to prepare a probe:

1. Connect to the Hardware Management Console or Integrated Virtualization Manager.

2. Add checkpoints.

3. Configure the checkpoints to send QoS data and alarms if the thresholds specified is breached.

Connecting to Hardware Management Console / Integrated Virtualization Manager

Perform the following steps to connect to Hardware Management Console/ Integrated Virtualization Manager.

1. Create a resource to be used as a connection to the IBM Virtualization setup. Using this connection, the probe collects and stores data and information from the monitored components.

2. Select the Default group in the left pane.

3. Tight-click the group and select New Resource from the shortcut menu.



The Resource dialog appears.

4. Adding all the values in respective fields.

5. Click the Test button to verify the connection to the host.

Following host response appears.

Note: The very first time you click the Test button after you have created your first resource, you may receive an error message. In that case, wait for at least 20 seconds and click the Test button again.

6. Click the Apply button in the probe GUI to activate the new resource configuration.

The new resource linking the probe to IBM server appears under the Default group.

IBMVM--IBM Virtualization Monitoring Properties

12 ibmvm Guide

Adding monitors (checkpoints)

As mentioned, the link to the IBM server is now established, but you have not yet selected any checkpoints.

Add monitors as described in the section Adding Checkpoints|bookmark=IBMVMAddingCheckpoints.

See also the section Using Templates|bookmark=IBMVMUsingTemplates.

When finished, click the Apply button in the probe GUI to activate the configuration.


The ibm window consists of a row of tool buttons and two window panes. In addition, a status bar is located at the bottom of the window, showing probe version information and when the probe was started.



The left pane

The left pane shows the monitoring groups containing the resources defined and the QoS definitions. Initially the Default Group and the standard QoS definitions are created and appears in the pane.

Groups

You can create new groups by right-clicking a group and selecting New Group (or by clicking the New Group tool button).

■ Resources

A group contains one or more resources. On this probe you can create one resource. This resource is configured as a link to the IBM server.

It is possible to move a resource from one group to another, using the drag and drop feature.

Templates

Templates are a useful tool for defining checkpoints to be monitored to on the various managed systems or Logical Partitions:

You may create templates and define a set of checkpoints belonging to that template. Drag and drop the template on the managed system/VM where you want to monitor the checkpoints defined for the template.

■ Right-clicking the Templates node lets you add a template.

■ Right-clicking one of the templates defined lets you edit or delete the selected template.

The properties for a template are Name and Description.


14 ibmvm Guide

See the section Using Templates|bookmark=IBMVMUsingTemplates for details.

QoS

The Qos node contains the standard QoS definitions included with the probe package. These can be selected when editing the monitoring properties for a monitor.

■ To define your own QoS definitions, right-click the QoS node and select New.

Right-clicking in the left pane

Right-clicking in the pane opens shortcut menu, which has following commands:

Command Description

New Resource It opens the Resource dialog, enabling you to define a new resource to be monitored. It is available only when a group or a resource is selected.

New Group It creates a new group where you may place resources. The new group appears in the pane with the name New Group. It is available only when a group or a resource is selected.

Right-click the new group and select rename to give the group a name of your own choice.

Edit It allows you to edit the properties for the selected resource. It is available only when a resource is selected.

Delete Let’s you delete the selected element (group, resource or QoS definition). Note that the Default group can not be deleted, but if you remove all elements from the group, it does not appear the next time you restart the probe.

■ QoS definitions when the QoS sub-node is selected in the left-pane.

Right-clicking in the right pane gives you the following possibilities:

■ When the QoS definitions are listed in the pane

Right-clicking in the list opens a shortcut menu, having commands to add (New) or delete a QoS definition.

■ When the resources are listed in the pane

Monitor Launches the monitor window and starts filling a graph with real time values measured on the selected monitor.


16 ibmvm Guide

Interval:

This interval is set to 10 seconds. Each 10 seconds the sample value is read from the probe, which means that the check interval set for the resource is vital. The value does not change until the next poll from the probe.

Samples:

The number of samples received since the monitor window was launched.

Average:

The average value of the samples received since the monitor window was launched.

Value:

The most recent value received since the monitor window was launched. The color of the indicator next to the number indicates the alarm state of the monitor. For example, green means that the alarm threshold defined for the monitor is not breached.

The tool buttons

The configuration tool also contains a row of tool buttons:

Button Name

The General Setup button

The New Group button

The New Resource button

The Message Pool Manager button

The New Template button

Description This is a description of the checkpoint. This description will be inserted into this field when the checkpoint is fetched from the IBM Server, but you are allowed to modify it.



Value Definition This drop-down list lets you select which value to be used, both for alarming and QoS:

You have the following options:

The current value, meaning that the most current value measured will be used.

The delta value (current –previous). This means that the delta value calculated from the current and the previous measured sample will be used.

Delta per second. This means that the delta value calculated from the samples measured within a second will be used.

The average value of the last and current sample: (current + previous) / 2.

Active This activates the monitoring of the probe.

Enable Monitoring Selecting this option activates the monitoring.

Note that the checkpoint will also be selected in the list of checkpoints in the right window pane when this option is selected, and that you can enable/disable monitoring of the checkpoint from that list.

Operator Select from the drop-down list the operator to be used when setting the alarm threshold for the measured value.

Example:

=> 90 means alarm condition if the measured value is above 90.

= 90 means alarm condition if the measured value is exact 90.

Threshold The alarm threshold value. An alarm message will be sent if this threshold is exceeded.

Unit This field specifies the unit of the monitored value.

(for example %, Mbytes etc.). The field is read-only.

Message Token Select the alarm message to be issued if the specified threshold value is breached. These messages are kept in the message pool. The messages can be modified in the Message Pool Manager.

Publish Quality of Service

Select this option if you want QoS messages to be issued on the checkpoint.

QoS Name Select the name to be used on the QoS message issued.

IBMVM--Using Templates

24 ibmvm Guide


Templates are a useful tool for defining checkpoints to be measured to on the various managed systems or logical partitions:

You may create templates and define a set of checkpoints belonging to that template. These templates can be applied to a managed system/VM by dragging and dropping the template on the managed system/VM where you want to measure the monitors defined for the template.

Creating a template

Right-click the Templates node in the left window pane and select New. Note that you may also edit an existing template by selecting one of the templates defined (found by expanding the Templates node and selecting Edit).

The Template Properties dialog appears, letting you specify a Name and a Description for the new template.



Adding checkpoint to the template

There are different ways to define monitors for a template:

■ Drag checkpoints from the right pane and drop on the template in the left pane.

■ Right-click a checkpoint/ and select Add to Template.

Applying a template to a managed system / logical partition

■ Drag and drop the template on the managed system/VM where you want to monitor the checkpoints defined for the template. Note that you may also drop the template on a node containing multiple managed system/VM. You will then be asked if you want to apply the template to all managed system/VM under the node.

The Select Template dialog appears, enabling you to select one of the templates defined.
