A large enterprise can have thousands of objects defined in vRealize Operations Manager. Creating object tags and tag values makes it easier to find objects and metrics in vRealize Operations Manager. With object tags, you select the tag value assigned to an object and view the list of objects that are associated with that tag value.
A tag is a type of information, such as Adapter Types. Adapter Types is a predefined tag in vRealize Operations Manager. Tag values are individual instances of that type of information. For example, when vRealize Operations Manager discovers objects using the vCenter Adapter, it assigns all the objects to the vCenter Adapter tag value under the Adapter Types tag.
You can assign any number of objects to each tag value, and you can assign a single object to tag values under any number of tags. You typically look for an object by looking under its adapter type, its object type, and possibly other tags.
If an object tag is locked, you cannot add objects to it. vRealize Operations Manager maintains locked object tags.
