# Using Your Own Alerting

Two well-maintained projects are [Cabot](https://github.com/arachnys/cabot) and [Seyren](https://github.com/scobal/seyren).

### Connecting Hosted Graphite to Open Source Alerting Tools

Connecting Hosted Graphite to open source Alerting tools is a simple process.

* First, you need to create an [*access key*](/account-management/access-keys.md).
* Right-click the URL of the access key, and copy it.
* Use this value as your Graphite URL in your alerting system.

### Using Hosted Graphite with Cabot

```
GRAPHITE_API: Your Access Key URL
GRAPHITE_USER:
GRAPHITE_PASS:
GRAPHITE_FROM: -10min
```

Both **GRAPHITE\_USER** and **GRAPHITE\_PASS** should be left empty, they’re not necessary when using the [Access Key.](/account-management/access-keys.md)

Note **GRAPHITE\_API** should end with a `‘/’` character.

### Using Hosted Graphite with Seyren

Set the **GRAPHITE\_URL** to your Access key URL as either a system property or an environment variable when starting Seyren. In the simplest case:

```python
export GRAPHITE_URL=Your access Key URL
java -jar seyren-1.2.0.jar
open http://localhost:8080
```
