Classifications

Entities in Obcerv are identified by their unique set of dimensions. However, different data sources may use different conventions for assigning dimensions. This means that entities that are similar conceptually may have very different dimensions and be difficult to capture in one query.

Consider the following two entities as an example:

• Geneos data: [probe=CENTOS7-MLG5, managedEntity=CENTOS7-MLG5, type=All, sampler=Disk, dataview=Disk, row=/boot]
• Collection Agent plugin data: [hostname, device, volume]

Both entities represent disks, but have very different dimensions.

To resolve this problem you can create policies that assign special attributes to entities called classifications. You can then use classifications to easily create simple queries.

The Classifications page shows all current policies used to assign classification attributes.

Create a new classification policy Copied

To create a new policy that assigns classifications:

1. Click Edit to enter editing mode.
2. Click the Add rule button.
3. Specify an Attribute Name. This is the attribute that attached to all entities this policy effects.
4. Specify one or more policy rules. You must specify an Attribute Value and a pattern that defines Where each policy rule is applied. To do this use an Expression.
5. (optional) If you have set multiple policy rules you can order them using the arrow buttons.
6. Click OK, then click Save.

Edit a classification policy Copied

To update an existing classification policy:

1. Click Edit to enter editing mode.
2. Select the menu button of the policy you want to change, then click Edit.
3. Modify the Attribute Name.
4. Add or modify policy rules. If you have set multiple policy rules you can order them using the arrow buttons or delete them using the delete button.
5. Click OK, then click Save.
