Setting event thresholds in the operator console

The display of threshold options depends on the access type of the monitor and permission to set thresholds. You can set thresholds on a monitor only if you have write access to the monitor (user group is present in the WLS field of the CI to which the monitor is associated), and permission to set instance or global thresholds. If you select an event on which to set the threshold, and the CI to which the event belongs has write access, only then are the various threshold options displayed in the Tools menu. 

If the threshold is an instance threshold and the user has permission to set instance thresholds, then the instance thresholds menu will be displayed.

 

Note

Do not use the operator console to set global thresholds. Instead, use the TrueSight console to set thresholds, as described in Managing-global-thresholds-on-TrueSight-console.

Best practice

 Always make global threshold changes from the TrueSight console for the following reasons:

  • The changes made at the TrueSight console are propagated to all TrueSight Infrastructure Management Server instances in your tenant.
  • Global threshold changes done at the TrueSight Infrastructure Management Server-level are only applied locally and are not propagated to other Infrastructure Management servers.
  • Restarting a TrueSight Infrastructure Management Server after making the global threshold changes locally causes global thresholds from the TrueSight Presentation Server to be reapplied to the Infrastructure Management Server local changes done at the TrueSight Infrastructure Management Server  before a restart are overridden.
In addition, before configuring the global thresholds settings, ensure that the monitor type exists in the TrueSight Infrastructure Manager. Suppose if it does not exist at the time of configuring global thresholds and you added the monitor type later, then either restart the TrueSight Infrastructure Management Server or edit and save the global threshold settings for the monitor type again from the TrueSight console for the settings to be applied.

Note

In the BMC Cloud Lifecycle Management environment, out-of-the-box threshold values are not set for storage and network monitor types. This is because these values are absolute values in BMC Cloud Lifecycle Management, and a range cannot be set for such values.

If you have permission to set both instance and global thresholds, both of the threshold options will be displayed. 

 Note that the Intelligent Event history page represents the event and the threshold on which the event was raised. If the event was generated by setting an instance threshold, and the user has instance threshold permission, then only the instance threshold option is displayed in the Intelligent Event history page.

When a user does not have permission to set thresholds (instance and global), the following changes are evident in the display: 

  • The Threshold link in Options > Administration appears as locked. 
  • The Tools menu for monitors does not show the thresholds-related menu options. 

     Click the Advanced link to set thresholds with minimum sampling window, threshold, absolute deviation, and percentage deviation. This option is applicable only for Signature and Abnormality Event thresholds.

To set event thresholds

  1. On the Event Summary tab in the operator console, select any one of the following tabs:
    • Group Matrix
    • Device Matrix
  2. Click the Device link of the device name to view the list of monitors under the device.

  3. From the Tools list, select the threshold to create based on the type of threshold (absolute, signature, or abnormality) and the level of coverage (event).

    Note

    Alternatively, you can reach the threshold setting through the Options> Administration tab. Click the Edit link beside Intelligent Event Thresholds and then click Edit for the relevant monitor type and threshold type.

    To set Abnormality Event thresholds, click the Edit link beside Abnormality Events.

  4. Set threshold values for the relevant attributes by using the parameters displayed on the Edit Thresholds screen, as summarized in the following table.

    Parameters for thresholds    The [confluence_table-plus] macro is a standalone macro and it cannot be used inline. Click on this message for details.

    Note

    Click the Advanced link to set thresholds with minimum sampling window, threshold, absolute deviation, and percentage deviation. This option is applicable only for Signature and Abnormality Event thresholds.

  5. Select the Enabled check boxes for all relevant attributes, and then click Apply.
