The Thresholds Summary dashlet lists the thresholds for the selected managed object. Here you can enable/disable thresholds, and set custom values. The Thresholds Summary dashlet is applicable to all data sources.
Thresholds are trigger points that, when they are crossed, cause ENA to raise events. You can set thresholds against an individual event, a managed object, View, or all objects on an Entuity server. For further information on what you can do with thresholds with regards to events and incidents, please see the Events section.
To add a Thresholds Summary dashlet to a custom dashboard:
- When adding a dashlet to a new custom dashboard or editing an existing custom dashboard, follow the instructions for adding a dashlet, select Thresholds Summary in the Select Dashlet Type, and click Next.
- The Create Dashlet form will slide in on the right. Enter a name for your dashlet in the Name field.
- You can then choose the source of the data to be displayed in the dashlet.
- If you want this dashlet to source its data from the context of its parent dashboard, select Dashboard. You can see the context of the parent dashboard in the Dashboard Context field at the top of the form.
- If you want this dashlet to source its data from another dashlet in this current dashboard, select Dashlet.
- If you want this dashlet to source its data from a specific managed object on your network, select Fixed Object. You can then click Browse to an object to search for the managed object in Explorer, or drag into the box your desired managed object in from another browser window.
- Click the Advanced Settings field to open the Advanced Settings form.
- Choose whether you want to hide the title of the dashlet in the Hide Title Bar field. If selected, the dashlet's Overflow Menu will also be hidden, but in the Promote Menu Options field you can then choose if you want to display the options in the dashlet's Overflow Menu in the overall dashboard's Overflow Menu.
- Choose whether you want the dashlet to automatically refresh in the Auto Refresh field. By default this is set to On.
- Click Done in the top right of the form to save and return to the Create Dashlet form, otherwise click Cancel.
- Click Done in the top right of the form, otherwise click Cancel.
To configure or export the table in the dashlet:
Please see the article on configuring tables in ENA.
In the Thresholds Related To field, you can view thresholds relating to managed objects under the selected managed object, e.g. when you have selected a View, you can see the threshold details for devices, and when you have selected a device, you can see the threshold details for ports, processors, VPNs etc. Select which object you want to view threshold details for and the table in the dashlet will update accordingly.
|Column Name||Column Description|
|Threshold Name||name of the attribute threshold.|
|Group||the group to which the threshold is applied.|
|Enabled||indicates if the threshold is enabled.|
|Value||the value of the threshold.|
|Overriden||indicates if the threshold has been changed from the default value, i.e. enabled/disabled and/or had its threshold value changed.|
To set/override a threshold:
By default, each threshold is either enabled/disabled and has a default value. If you choose to disable/enable a threshold (i.e. change it from the default setting), and/or change the threshold value, then the threshold will be classed as overriden (i.e. the value in the Overriden column will be 'Yes').
Note, users require the Event Administration permission to edit thresholds. Any user without this permission can still see thresholds, so long as they have access to a dashboard with this dashlet in it.
- Navigate to and select the threshold you want to override.
- In the dashlet Overflow Menu, the Context Menu of the selected threshold, or at the top of the dashlet, click Set Override.
- The Set Override form will slide in on the right.
- If you want to change the threshold value, enter the figure you want in the Value field.
- If you want to enable/disable the threshold, make the change in the Enable field.
- Click Done in the top right to save your changes, otherwise click Cancel.
- If you have made any changes, the value in the Overriden column of the dashlet table will be 'Yes'.
To set a system-level threshold, open the Thresholds dashboard for the All Objects View and follow the above instructions.
Please see the section To set a dynamic threshold for information on setting dynamic thresholds.
To remove an override:
- Select the override that you would like to remove. Click Remove Override via the dashlet's Overflow Menu or the selected threshold's Context Menu.
- A confirmation window will open asking you to confirm the removal.
To view the threshold hierarchy:
Thresholds can be set at system, device and port level.
As a result, there is a hierarchy to how thresholds are applied. A particular level in the hierarchy will always inherit the threshold setting from the level above it, unless the user overrides it.
- Select the threshold that you want to see the hierarchy for.
- Click Show Hierarchy in the top right of the dashlet, or via the dashlet's Overflow Menu.
- The Threshold Hierarchy form will slide in on the right. This will list the hierarchy of thresholds from the top level (system) in descending order down to the selected level. It will display the managed object's name, whether the threshold is enabled, and the threshold's value.
