Host Groups

Host Groups let you organise hosts into logical collections — by environment (production / staging), team ownership, geography, or any other dimension that makes sense for your organisation.

Creating a Group

  1. Navigate to Hosts → Groups
  2. Click New Group
  3. Enter a name and optional description
  4. Click Create

Hosts can be added to a group from either the group detail page or the host detail page.

Using Groups

Scoped alert rules

Alert rules can be scoped to a specific host group. An alert rule scoped to production-web only fires for hosts in that group, reducing noise.

Bulk operations

Actions like running a custom script or checking service status can target an entire group rather than individual hosts.

RBAC resource scoping

Users with the engineer role can be granted access to specific host groups. Their access is limited to hosts within those groups — they cannot see or interact with hosts outside their assigned groups.

Group Membership

A host can belong to multiple groups. Group membership is managed from:

  • The group detail page (/hosts/groups/[id]) — add/remove hosts in bulk
  • The host detail page — add/remove the host from individual groups

Comparing Hosts

The host comparison view (/hosts/[id]/compare) lets you select two or more hosts from the same group and view their metrics side by side. Useful for identifying outliers.
