# Kelola aplikasi dengan AWS Panorama API
<a name="api-applications"></a>

Anda dapat memantau dan mengelola aplikasi dengan AWS Panorama API.

## Lihat aplikasi
<a name="api-applications-view"></a>

Untuk mendapatkan daftar aplikasi yang berjalan pada alat, gunakan [ListApplicationInstances](https://docs.aws.amazon.com/panorama/latest/api/API_ListApplicationInstances.html)API.

```
$ aws panorama list-application-instances
    "ApplicationInstances": [
        {
            "Name": "aws-panorama-sample",
            "ApplicationInstanceId": "applicationInstance-ddaxxmpl2z7bg74ywutd7byxuq",
            "DefaultRuntimeContextDevice": "device-4tafxmplhtmzabv5lsacba4ere",

## Kelola aliran kamera
<a name="api-applications-cameras"></a>

Anda dapat menjeda dan melanjutkan node aliran kamera dengan [SignalApplicationInstanceNodeInstances](https://docs.aws.amazon.com/panorama/latest/api/API_SignalApplicationInstanceNodeInstances.html)API.

```
$ aws panorama signal-application-instance-node-instances --application-instance-id applicationInstance-ddaxxmpl2z7bg74ywutd7byxuq \
        --node-signals '[{"NodeInstanceId": "camera_node_override", "Signal": "PAUSE"}]'
{
    "ApplicationInstanceId": "applicationInstance-ddaxxmpl2z7bg74ywutd7byxuq"
}
```

Dalam skrip, Anda bisa mendapatkan daftar node dan memilih salah satu untuk menjeda atau melanjutkan secara interaktif.

**Example [pause-camera.sh](https://github.com/awsdocs/aws-panorama-developer-guide/blob/main/util-scripts/pause-camera.sh) - penggunaan**  

```
my-app$ ./pause-camera.sh

Getting nodes...
0: SAMPLE_CODE              RUNNING
1: warehouse-floor          RUNNING
2: hdmi_data_sink           RUNNING
3: entrance-north           PAUSED
4: SQUEEZENET_PYTORCH       RUNNING
Choose a node

Signalling node warehouse-floor
+ aws panorama signal-application-instance-node-instances --application-instance-id applicationInstance-r3a7xmplcbmpjqeds7vj4b6pjy --node-signals '[{"NodeInstanceId": "warehouse-floor", "Signal": "PAUSE"}]'
{
    "ApplicationInstanceId": "applicationInstance-r3a7xmplcbmpjqeds7vj4b6pjy"
}
```

Dengan menjeda dan melanjutkan node kamera, Anda dapat memutar melalui sejumlah besar aliran kamera daripada yang dapat diproses secara bersamaan. Untuk melakukan ini, petakan beberapa aliran kamera ke simpul input yang sama di manifes penggantian Anda.

Dalam contoh berikut, manifes override memetakan dua aliran kamera, `warehouse-floor` dan `entrance-north` ke node input yang sama ()`camera_node`. `warehouse-floor`Aliran aktif saat aplikasi dimulai dan `entrance-north` node menunggu sinyal menyala.

**Example [timpalan-multicam.json](https://github.com/awsdocs/aws-panorama-developer-guide/blob/main/sample-apps/aws-panorama-sample/graphs/my-app/override-multicam.json)**

                    }
                ]
            }
```
