# CCMetric receivers
|
|
|
|
This folder contains the ReceiveManager and receiver implementations for the cc-metric-collector.
|
|
|
|
# Configuration
|
|
|
|
The configuration file for the receivers is a list of configurations. The `type` field in each specifies which receiver to initialize.
|
|
|
|
```json
|
|
[
|
|
{
|
|
"type": "nats",
|
|
"address": "nats://my-url",
|
|
"port" : "4222",
|
|
"database": "testcluster"
|
|
}
|
|
]
|
|
```
|
|
|
|
|
|
## Type `nats`
|
|
|
|
```json
|
|
{
|
|
"type": "nats",
|
|
"address": "<nats-URI or hostname>",
|
|
"port" : "<portnumber>",
|
|
"database": "<subscribe topic>"
|
|
}
|
|
```
|
|
|
|
The `nats` receiver subscribes to the topic `database` and listens on `address` and `port` for metrics in the InfluxDB line protocol.
|
|
|
|
# Contributing own receivers
|
|
A receiver contains three functions and is derived from the type `Receiver` (in `metricReceiver.go`):
|
|
* `Init(config ReceiverConfig) error`
|
|
* `Start() error`
|
|
* `Close()`
|
|
* `Name() string`
|
|
* `SetSink(sink chan ccMetric.CCMetric)`
|
|
|
|
The data structures should be set up in `Init()` like opening a file or server connection. The `Start()` function should either start a go routine or issue some other asynchronous mechanism for receiving metrics. The `Close()` function should tear down anything created in `Init()`.
|
|
|
|
Finally, the receiver needs to be registered in the `receiveManager.go`. There is a list of receivers called `AvailableReceivers` which is a map (`receiver_type_string` -> `pointer to Receiver interface`). Add a new entry with a descriptive name and the new receiver.
