1.3.1. Performing Searches in Red Hat Virtualization

The Administration Portal allows you to manage thousands of resources, such as virtual machines, hosts, users, and more. To perform a search, enter the search query (free-text or syntax-based) into the search bar, available on the main page for each resource. Search queries can be saved as bookmarks for future reuse, so you do not have to reenter a search query each time the specific search results are required. Searches are not case sensitive.

1.3.2. Search Syntax and Examples

The syntax of the search queries for Red Hat Virtualization resources is as follows:

result type: {criteria} [sortby sort_spec]

Syntax Examples

The following examples describe how the search query is used and help you to understand how Red Hat Virtualization assists with building search queries.

Table 1.15. Example Search Queries
ExampleResult

Hosts: Vms.status = up page 2

Displays page 2 of a list of all hosts running virtual machines that are up.

Vms: domain = qa.company.com

Displays a list of all virtual machines running on the specified domain.

Vms: users.name = Mary

Displays a list of all virtual machines belonging to users with the user name Mary.

Events: severity > normal sortby time

Displays the list of all Events whose severity is higher than Normal, sorted by time.

1.3.3. Search Auto-Completion

The Administration Portal provides auto-completion to help you create valid and powerful search queries. As you type each part of a search query, a drop-down list of choices for the next part of the search opens below the Search Bar. You can either select from the list and then continue typing/selecting the next part of the search, or ignore the options and continue entering your query manually.

The following table specifies by example how the Administration Portal auto-completion assists in constructing a query:

Hosts: Vms.status = down

Table 1.16. Example Search Queries Using Auto-Completion
InputList Items DisplayedAction

h

Hosts: Vms.s

Select status or type status

Hosts: Vms.status

!=

Select or type =

Hosts: Vms.status =

All status values

Select or type down

1.3.4. Search Result Type Options

The result type allows you to search for resources of any of the following types:

  • Vms for a list of virtual machines
  • Host for a list of hosts
  • Pools for a list of pools
  • Template for a list of templates
  • Events for a list of events
  • Users for a list of users
  • Cluster for a list of clusters
  • DataCenter for a list of data centers
  • Storage for a list of storage domains

As each type of resource has a unique set of properties and a set of other resource types that it is associated with, each search type has a set of valid syntax combinations. You can also use the auto-complete feature to create valid queries easily.

1.3.5. Search Criteria

You can specify the search criteria after the colon in the query. The syntax of {criteria} is as follows:

<prop><operator><value>

or

<obj-type><prop><operator><value>

Examples

The following table describes the parts of the syntax:

Table 1.17. Example Search Criteria
PartDescriptionValuesExampleNote

prop

The property of the searched-for resource. Can also be the property of a resource type (see obj-type), or tag (custom tag).

Limit your search to objects with a certain property. For example, search for objects with a status property.

Status

N/A

obj-type

A resource type that can be associated with the searched-for resource.

These are system objects, like data centers and virtual machines.

Users

N/A

operator

Comparison operators.

=

!= (not equal)

>

<

>=

<=

N/A

Value options depend on property.

Value

What the expression is being compared to.

String

Integer

Ranking

Date (formatted according to Regional Settings)

Jones

256

normal

  • Wildcards can be used within strings.
  • "" (two sets of quotation marks with no space between them) can be used to represent an un-initialized (empty) string.
  • Double quotes should be used around a string or date containing spaces

1.3.6. Search: Multiple Criteria and Wildcards

Wildcards can be used in the <value> part of the syntax for strings. For example, to find all users beginning with m, enter m*.

You can perform a search having two criteria by using the Boolean operators AND and OR. For example:

Vms: users.name = m* AND status = Up

This query returns all running virtual machines for users whose names begin with "m".

Vms: users.name = m* AND tag = "paris-loc"

This query returns all virtual machines tagged with "paris-loc" for users whose names begin with "m".

When two criteria are specified without AND or OR, AND is implied. AND precedes OR, and OR precedes implied AND.

1.3.7. Search: Determining Search Order

You can determine the sort order of the returned information by using sortby. Sort direction (asc for ascending, desc for descending) can be included.

For example:

events: severity > normal sortby time desc

This query returns all Events whose severity is higher than Normal, sorted by time (descending order).
