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
{
"<name>": {
"type": "nats",
"address" : "nats-server.example.org",
"port" : "4222",
"subject" : "subject"
}
}
type: makes the receiver anatsreceiveraddress: Address of the NATS control serverport: Port of the NATS control serversubject: Subscribes to this subject and receive metrics
Debugging
-
Install NATS server and command line client
-
Start NATS server
nats-server --net nats-server.example.org --port 4222 -
Check NATS server works as expected
nats --server=nats-server-db.example.org:4222 server check -
Use NATS command line client to subscribe to all messages
nats --server=nats-server-db.example.org:4222 sub ">" -
Use NATS command line client to send message to NATS receiver
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"
