# Multi-Tenant Organizations (Cloud Enterprise)

Pulse supports isolated, multi-tenant organizations for MSPs, homelabs with multiple environments, and multi-datacenter deployments. Each organization gets its own infrastructure, resources, alerts, and audit log — fully isolated from other organizations on the same Pulse instance.

## Requirements

| Requirement | Detail |
|---|---|
| **Feature flag** | `PULSE_MULTI_TENANT_ENABLED=true` |
| **License** | Enterprise license with `multi_tenant` capability |

Without these, all API calls return `501 Not Implemented` (flag off) or `402 Payment Required` (no license). The **default** organization always works regardless.

## Quick Start

1. Set `PULSE_MULTI_TENANT_ENABLED=true` in your environment and restart Pulse.
2. Activate your Enterprise license in **Settings → License**.
3. Go to **Settings → Organization** and click **Create Organization**.
4. Name your organization and assign infrastructure to it.
5. Use the **Org Switcher** in the header bar to switch between organizations.

## Concepts

### Organizations

An organization is a fully isolated monitoring environment:

- Its own set of monitored nodes and resources.
- Its own alerts, thresholds, and notifications.
- Its own audit log.
- Its own configuration directory on disk.

The **default** organization always exists and is used when multi-tenant is disabled. It cannot be deleted or renamed.

### Roles

Each member has a role within an organization:

| Role | Permissions |
|---|---|
| **Owner** | Full control. Can transfer ownership, delete the org. |
| **Admin** | Manage members, shares, and org settings. Cannot transfer ownership. |
| **Editor** | Read/write access to org resources. Cannot manage members or shares. |
| **Viewer** | Read-only access to all org data. |

### Resource Sharing

Organizations can share specific resources with other organizations:

- Share a VM, container, host, or storage resource with another org.
- Assign an access role (`viewer`, `editor`, or `admin`) to the share.
- The receiving org sees shared resources alongside their own, with a share badge.

## Managing Organizations

### Creating an Organization

**UI:** Settings → Organization → Create Organization

**API:**
```bash
curl -X POST http://localhost:7655/api/orgs \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "Production Datacenter", "description": "EU production infrastructure"}'
```

### Switching Organizations

Use the **Org Switcher** dropdown in the header. When you switch:

- All pages reload with the new organization's data.
- AI chat history is reset (each org has its own context).
- Caches are invalidated and re-fetched.

### Managing Members

**UI:** Settings → Organization → Access

**API:**
```bash
# List members
curl http://localhost:7655/api/orgs/{orgId}/members \
  -H "Authorization: Bearer $TOKEN"

# Add a member
curl -X POST http://localhost:7655/api/orgs/{orgId}/members \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"userId": "user-id", "role": "editor"}'

# Update role
curl -X PATCH http://localhost:7655/api/orgs/{orgId}/members/{userId} \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"role": "admin"}'
```

### Sharing Resources

**UI:** Settings → Organization → Sharing

**API:**
```bash
# Create a share
curl -X POST http://localhost:7655/api/orgs/{orgId}/shares \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "targetOrgId": "other-org-id",
    "resourceType": "host",
    "resourceId": "resource-id",
    "role": "viewer"
  }'

# View incoming shares
curl http://localhost:7655/api/orgs/{orgId}/shares/incoming \
  -H "Authorization: Bearer $TOKEN"
```

## Settings Panels

When multi-tenant is enabled, **Settings → Organization** shows:

| Panel | Description |
|---|---|
| **Overview** | Organization name, description, creation date |
| **Access** | Member list, invite/remove members, change roles |
| **Sharing** | Outgoing and incoming resource shares |
| **Billing & Plan** | Organization-level plan and license info |

## API Reference

| Method | Endpoint | Description |
|---|---|---|
| `GET` | `/api/orgs` | List organizations the current user can access |
| `POST` | `/api/orgs` | Create a new organization |
| `GET` | `/api/orgs/{id}` | Get organization details |
| `PATCH` | `/api/orgs/{id}` | Update organization |
| `DELETE` | `/api/orgs/{id}` | Delete organization |
| `GET` | `/api/orgs/{id}/members` | List members |
| `POST` | `/api/orgs/{id}/members` | Add a member |
| `PATCH` | `/api/orgs/{id}/members/{userId}` | Update member role |
| `DELETE` | `/api/orgs/{id}/members/{userId}` | Remove a member |
| `GET` | `/api/orgs/{id}/shares` | List outgoing shares |
| `GET` | `/api/orgs/{id}/shares/incoming` | List incoming shares |
| `POST` | `/api/orgs/{id}/shares` | Create a share |
| `DELETE` | `/api/orgs/{id}/shares/{shareId}` | Remove a share |

### Tenant Context

All data-fetching endpoints respect the active organization context. The active org is determined by:

1. `X-Pulse-Org-ID` header (API clients)
2. Session cookie (browser)
3. Falls back to the `default` organization

## Storage

- The **default** org uses the root data directory (backward compatible).
- Non-default orgs store data in `{data-dir}/orgs/{org-id}/`.
- Organization metadata is stored in `org.json` inside each org directory.
- When multi-tenant is first enabled, legacy single-tenant data is migrated into `orgs/default/` with symlinks for compatibility.

## Troubleshooting

### "Multi-tenant is not enabled on this server" (501)

Set `PULSE_MULTI_TENANT_ENABLED=true` in your environment and restart Pulse.

### "Multi-tenant requires an Enterprise license" (402)

Activate an Enterprise license with the `multi_tenant` capability in **Settings → License**.

### Organization data not loading after switch

1. Hard-refresh the browser (`Ctrl+Shift+R`).
2. Check the Org Switcher dropdown — ensure the correct org is selected.
3. Check Pulse logs for tenant middleware errors.

### Shared resources not appearing

1. Verify the share exists: **Settings → Organization → Sharing → Incoming**.
2. Confirm the share role grants sufficient access.
3. Check that the source org's resources are online.
