# Custom Script

Compared with traditional monitoring services, **Tianji** supports custom scripts to support more customized scenarios.

Here is some example

## Examples

### get tailchat available service number from health endpoint

```js
const res = await request({
  url: 'https://<tailchat-server-api>/health'
})

if(!res || !res.data || !res.data.services) {
  return -1
}

return res.data.services.length
```

### get github star count

```js
const res = await request({
  url: 'https://api.github.com/repos/msgbyte/tianji'
})

return res.data.stargazers_count ?? -1
```

replace `msgbyte/tianji` to your own repo name

### get docker pull count

```js
const res = await request({
  url: "https://hub.docker.com/v2/repositories/moonrailgun/tianji/"
});

return res.data.pull_count;
```

replace `moonrailgun/tianji` to your own image name


### or more

Very very welcome to submit your script in this page. Tianji is driven by open source community.
