## `nats` receiver
|
|
|
|
The `nats` receiver can be used receive metrics from the NATS network. The `nats` receiver subscribes to the topic `database` and listens on `address` and `port` for metrics in the InfluxDB line protocol.
|
|
|
|
### Configuration structure
|
|
|
|
```json
|
|
{
|
|
"<name>": {
|
|
"type": "nats",
|
|
"address" : "nats-server.example.org",
|
|
"port" : "4222",
|
|
"subject" : "subject"
|
|
}
|
|
}
|
|
```
|
|
|
|
- `type`: makes the receiver a `nats` receiver
|
|
- `address`: Address of the NATS control server
|
|
- `port`: Port of the NATS control server
|
|
- `subject`: Subscribes to this subject and receive metrics
|
|
|
|
### Debugging
|
|
|
|
- Install NATS server and command line client
|
|
- Start NATS server
|
|
|
|
```bash
|
|
nats-server --net nats-server.example.org --port 4222
|
|
```
|
|
|
|
- Check NATS server works as expected
|
|
|
|
```bash
|
|
nats --server=nats-server-db.example.org:4222 server check
|
|
```
|
|
|
|
- Use NATS command line client to subscribe to all messages
|
|
|
|
```bash
|
|
nats --server=nats-server-db.example.org:4222 sub ">"
|
|
```
|
|
|
|
- Use NATS command line client to send message to NATS receiver
|
|
|
|
```bash
|
|
nats --server=nats-server-db.example.org:4222 pub subject \
|
|
"myMetric,hostname=myHost,type=hwthread,type-id=0,unit=Hz value=400000i 1694777161164284635
|
|
myMetric,hostname=myHost,type=hwthread,type-id=1,unit=Hz value=400001i 1694777161164284635"
