Resource Selectors

Resource Selectors are used throughout Mission Control for:

• Creating relationships between configs and configs/components
• Filtering resources in playbook triggers and actions
• Selecting targets for health checks
• Building dynamic views and dashboards

Field	Description	Scheme	Required
id	Select resource by ID. Supports comma-separated values and wildcards (id=abc*,def*)	string
name	Select resource by name. Supports comma-separated values and wildcards (name=*-prod,*-staging)	string
namespace	Select resources in this namespace only. If empty, selects from all namespaces	string
types	Select resources matching any of the specified types (e.g., Kubernetes::Pod, AWS::EC2::Instance)	[]string
statuses	Select resources matching any of the specified statuses	[]string
health	Select resources matching the specified health status. Supports multiple values separated by comma (healthy,warning) and negation (!unhealthy)	string
scope	Limit selection to resources belonging to a specific parent. For configs this is the scraper id, for checks it's the canary, and for components it's the topology. Can be a UUID or namespace/name	string
labelSelector	Kubernetes-style label selector. Supports =, ==, != operators and set-based selectors (key in (v1,v2), key notin (v1,v2), key, !key)	LabelSelector
fieldSelector	Select resources by property fields using Kubernetes field selector syntax. Supports fields like owner, topology_id, parent_id for components	FieldSelector
tagSelector	Select resources by tags using the same syntax as labelSelector. Tags are key-value pairs assigned during scraping	string
agent	Select resources created on a specific agent. Accepts agent UUID, agent name, or special values: local (resources without an agent), self (alias for local), all (resources from any agent). Defaults to local	string
cache	Cache settings for selector results. Useful for expensive or frequently-used selectors. Values: no-cache (bypass but allow caching), no-store (bypass and don't cache), max-age=<duration> (cache for duration)	string
limit	Maximum number of resources to return	int
includeDeleted	Include soft-deleted resources in results. Defaults to false	bool
search	Full-text search across resource name, tags, and labels using parsing expression grammar. See Search	string

Wildcards and Negation

The name, id, types, statuses, and health fields support:

• Prefix matching: name=prod-* matches names starting with prod-
• Suffix matching: name=*-backend matches names ending with -backend
• Negation: health=!unhealthy excludes unhealthy resources
• Multiple values: types=Kubernetes::Pod,Kubernetes::Deployment matches either type

Search

The search field provides a powerful query language for filtering resources.

Syntax

field1=value1 field2>value2 field3=value3* field4=*value4

Multiple conditions are combined with AND logic. Use | to combine conditions with OR logic.

type=Kubernetes::Pod | type=Kubernetes::Deployment

Parentheses can be used for grouping:

(type=Kubernetes::Pod | type=Kubernetes::Deployment) health=unhealthy

A bare word (without a field name) is treated as a name prefix search:

nginx

is equivalent to name=nginx*.

Operators

Operator	Example	Description	Types
=	status=healthy	Equals (exact match or wildcard)	string int json
!=	health!=unhealthy	Not equals	string int json
=*	name=*-prod or name=api-*	Prefix or suffix match	string int
>	created_at>now-24h	Greater than	datetime int
<	updated_at<2025-01-01	Less than	datetime int
>=	cost_total_30d>=100	Greater than or equal	datetime int
<=	cost_total_30d<=1000	Less than or equal	datetime int

Existence Checks

Check whether a label, tag, or property key exists (or does not exist):

labels.app          # matches resources that have the label "app"
!labels.app         # matches resources that do NOT have the label "app"
tags.environment    # matches resources that have the tag "environment"
!tags.environment   # matches resources that do NOT have the tag "environment"
properties.cpu      # matches resources with a "cpu" property
!properties.cpu     # matches resources without a "cpu" property

Date Queries

• Absolute dates: 2025-01-15, 2025-01-15T10:30:00Z
• Relative dates: now-24h, now-7d, now+1w
• Supported units: s (seconds), m (minutes), h (hours), d (days), w (weeks), y (years)

JSON Field Access

Access nested fields in labels, tags, and config using dot notation:

labels.app=nginx
tags.env=production
config.spec.replicas>3

Type Prefix Matching

The type field supports partial matching — a search for a short type name will match against all known types by suffix. For example:

type=pod          # matches Kubernetes::Pod
type=Deployment   # matches Kubernetes::Deployment
type=EC2          # matches AWS::EC2::Instance

Common Fields

These fields are available in any search query regardless of resource type:

Field	Description
limit	Limit the number of results returned
sort	Sort results by a column. Prefix with - for descending order
offset	Skip the first N results
@order	Alias for sort
