# Prometheus scrape target metric names
|
||
|
||
Here are ready‑to‑run **cURL** commands you can use to query each Prometheus scrape target and list the metric names they expose.
|
||
The Prometheus HTTP API endpoint `http://localhost:9090/api/v1/label/__name__/values` returns all metric names currently known for the target’s job/instance.
|
||
|
||
## 1. Chat (`http://chat:3000/metrics`)
|
||
|
||
[Browse `chat`](http://192.168.88.40:9090/api/v1/label/__name__/values?match[]={job=%22chat%22})
|
||
|
||
```bash
|
||
curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="chat",instance="chat:3000"}' | jq .
|
||
```
|
||
|
||
see [Prometheus Results](./prometheus_results.md#chat-metrics) for full output of all 20+ metric names exposed by the Chat service.
|
||
|
||
## 2. NGINX exporter (`http://nginx-exporter:9113/metrics`)
|
||
|
||
```bash
|
||
curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="nginx",instance="nginx-exporter:9113"}' | jq .
|
||
```
|
||
|
||
see [Prometheus Results](./prometheus_results.md#nginx-metrics) for full output of all 40+ metric names exposed by the NGINX exporter.
|
||
|
||
## 3. Node exporter (`http://node-exporter:9100/metrics`)
|
||
|
||
```bash
|
||
curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="node",instance="node-exporter:9100"}' | jq .
|
||
```
|
||
|
||
see [Prometheus Results](./prometheus_results.md#node-metrics) for full output of all 200+ metric names exposed by the Node exporter.
|
||
|
||
## 4. Playout (`http://playout:8081/metrics`)
|
||
|
||
```bash
|
||
curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="playout",instance="playout:8081"}' | jq .
|
||
```
|
||
|
||
see [Prometheus Results](./prometheus_results.md#playout-metrics) for full output of all 10+ metric names exposed by the Playout service.
|
||
|
||
## 5. Postgres exporter (`http://postgres-exporter:9187/metrics`)

||
|
||
```bash
|
||
curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="postgres",instance="postgres-exporter:9187"}' | jq .
