This topic provides information about performing various functions related to tags, such as performing a tag-based search, tag filtering, using the tag cloud, adding tags, editing tags, and deleting tags.

Using tags

A tag is a text label associated with a TrueSight Capacity Optimization object that improves search results and applies an additional level of filtering where needed. Tags are used to indicate a particular feature of the object that distinguishes it from other objects. TrueSight Capacity Optimization provides a set of useful tags; you can also define custom tags for your specific needs.

Tags are grouped by tag type; for example:

  • Environment, for example, PRODUCTION or TEST
  • Attention level, for example, BUSINESS_CRITICAL
  • Type of service, for example, CRM
  • Tier, for example, BACKEND

Performing a tag-based search

The TrueSight Capacity Optimization search engine allows you to search for objects that match the given tags.

For example, you can search for systems with tags "x86" and "VMware" using the search string:

x86 AND VMware

or, to only restrict the search to tags:

tag:x86 AND tag:VMware

For more information, see Searching for entities and metrics.

Performing tag-based filtering

You can use tags to filter the results of analyses, models, and so on by using entity filters that is tag-based search conditions that are applied as filters.

For example, you can define a filter to identify systems with tags "x86" and "VMware" saving the search as an entity filter. For more information, see Managing entity filters.

Using the tag cloud

The Tag List portlet shows a tag cloud where all used tags are displayed using a font size proportional to their relative frequency. The most used tags are displayed by using a larger font and the least used tags are displayed by using a smaller font. For more information, see Tag List portlet.

Viewing, creating, editing, and deleting tags

You can view and edit tags associated with an object from the Using the description box of its detail page.

Example of a system with multiple tags

To add a new tag:

  1. Click Add tag and enter the following information:
    1. Tag: Name of the new tag
    2. Description: Brief description of the new tag
    3. Tag type: Choose the category, for example, CPU Family, Virtualization Technology, and so on
  2. Click Add Tag.

Additional information

When you start typing a tag name, you get a list of tags of the selected tag type. If you choose the Not specified (default) option, all the tag types are matched.

Adding and editing tags

If you click an existing tag, the Add Tag pop-up window appears, displaying a list of tags of the same type associated with the object.

To delete a tag, click  that appears when positioning the mouse pointer over the desired tag name.
