Setting a resource-monitor threshold

This topic describes how to set a resource-monitor threshold in IBM Director.

If you set a resource-monitor threshold for an attribute on a managed system or device, an event is generated when the threshold is met or exceeded. Most resource-monitor thresholds are numeric values, although for some resource monitors you can set text-string thresholds. If you set a text-string threshold, the text string you specify is monitored, and an event is generated if the text changes.

Complete the following steps to set a resource-monitor threshold:

  1. In the IBM Director Console Tasks pane, drag the Resource Monitors task onto the managed system, device, or group that you want to monitor.
  2. In the Available Resources pane of the Resource Monitors window, expand the tree; then, double-click the resource that you want to monitor. The resource is displayed in the Selected Resources pane.
  3. In the Selected Resources pane, right-click the resource attribute that you want to monitor. Then, do one of the following: If you dropped the Resource Monitors task onto an individual managed system or device, click Individual Threshold, or, if you dropped the Resource Monitors task onto a group, click Group Threshold .
  4. In the System Threshold window, type a name for the threshold and complete the applicable fields. The Enabled to generate events check box is selected by default, so if the threshold you set in this window is met or exceeded, an event is generated. If you want to be notified when an event is generated, you must set up an event action plan that uses a threshold event filter.

    If you select the Generate events on value change check box, you cannot specify a threshold value. An event is generated if the value changes for the specified attribute and the Enabled to generate events check box is selected.

    To monitor a text-string threshold, click Add in the Threshold strings group box. In the Add string threshold setting window, type the text that you want to monitor, and select an event type from the list; then, click OK. The text string and event type are displayed in the Threshold strings group box.

  5. Click OK. The threshold is set immediately.

If you set an individual threshold in the Resource Monitors window, a threshold icon is displayed in the data cell of the applicable attribute in the Selected Resources pane. In IBM Director Console, an icon is displayed beside the managed system in the Group Contents pane if the threshold state changes from Normal to Met or Exceeded.

If you set a group threshold, a threshold icon is displayed beside the applicable attribute in the Selected Resources column in the Selected Resources pane. If a threshold is met or exceeded on a managed system or device in the selected group, the data cell for the managed system that meets the criteria displays an icon indicating that the threshold has been met.

The following table describes the Resource-monitor status icons.
