# Load Balancer Quotas

> Configure per-project resource limits for Xloud Load Balancer instances, listeners, pools, and members.

## Overview

Quotas prevent individual projects from consuming excessive load balancing resources.
Default quota values are set platform-wide; administrators override them per project.
Load balancer quotas cover the full resource hierarchy — from the top-level load balancer
down to individual L7 rules.

<Warning>
  **Administrator Access Required** — This operation requires the `admin` role. Contact your
  Xloud administrator if you do not have sufficient permissions.
</Warning>

## Default Quota Reference

| Resource        | Default Limit | Description                                      |
| --------------- | ------------- | ------------------------------------------------ |
| `loadbalancer`  | 10            | Load balancer instances per project              |
| `listener`      | 50            | Listeners across all load balancers in a project |
| `pool`          | 50            | Pools across all load balancers in a project     |
| `member`        | 50            | Pool members per project                         |
| `healthmonitor` | 50            | Health monitors per project                      |
| `l7policy`      | 50            | L7 routing policies per project                  |

## View Quotas

<Tabs>
  <Tab title="Dashboard" icon="gauge">
    Navigate to the admin quota settings and scroll to the **Load Balancer** section
    to view platform-wide default quotas. Per-project overrides are visible in
    **Identity > Projects** (admin view) > Modify Quotas.
  </Tab>

  <Tab title="CLI" icon="terminal">
    ```bash title="Show platform-wide default quotas" theme={null}
    openstack loadbalancer quota defaults show
    ```

    ```bash title="Show quotas for a specific project" theme={null}
    openstack loadbalancer quota show <project-id>
    ```

    ```bash title="List quotas for all projects" theme={null}
    openstack loadbalancer quota list --all-projects
    ```
  </Tab>
</Tabs>

***

## Set Project Quotas

<Tabs>
  <Tab title="Dashboard" icon="gauge">
    Navigate to **Identity > Projects** (admin view). Select the project and click
    **Modify Quotas**. Scroll to the **Load Balancer** section and update the limits.
  </Tab>

  <Tab title="CLI" icon="terminal">
    ```bash title="Set project-specific quotas" theme={null}
    openstack loadbalancer quota set \
      --loadbalancer 20 \
      --listener 100 \
      --pool 100 \
      --member 200 \
      --healthmonitor 50 \
      <project-id>
    ```

    ```bash title="Reset project to platform defaults" theme={null}
    openstack loadbalancer quota delete <project-id>
    ```
  </Tab>
</Tabs>

<Tip>
  Increase quotas for production projects that run multiple microservices behind
  separate load balancers. Keep development and test project quotas at defaults
  to control infrastructure costs.
</Tip>

## Monitor Quota Consumption

Regularly review quota consumption to identify projects approaching limits:

```bash title="List all project quotas sorted by load balancer count" theme={null}
openstack loadbalancer quota list --all-projects \
  -f json | python3 -c "
import json, sys
quotas = json.load(sys.stdin)
for q in sorted(quotas, key=lambda x: x.get('loadbalancer', 0), reverse=True)[:10]:
    print(f'{q.get(\"loadbalancer\",0):4d} LBs  {q[\"project_id\"]}')
"
```
