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.

{
  "myreceivername" : {
    "type": "receiver-type",
    <receiver-specific configuration>
  }
}

This allows to specify

Available receivers

nats: Receive metrics from the NATS network
prometheus: Scrape data from a Prometheus client
http: Listen for HTTP Post requests transporting metrics in InfluxDB line protocol
ipmi: Read IPMI sensor readings
redfish Use the Redfish (specification) to query thermal and power metrics

Contributing own receivers

A receiver contains a few functions and is derived from the type Receiver (in metricReceiver.go):

For an example, check the sample receiver
