Metrics publishing

By default, the Streamr SDK is configured to publish metrics to the Streamr Network at regular intervals. The metrics include, for example, information about data volumes passing through the node, and are attributed to your node id. Here's the content of the metrics messages:

{
    node: {
        id: string
        broadcastMessagesPerSecond: number
        broadcastBytesPerSecond: number
        sendMessagesPerSecond: number
        sendBytesPerSecond: number
        receiveMessagesPerSecond: number
        receiveBytesPerSecond: number
        connectionAverageCount: number
        connectionTotalFailureCount: number
    },
    period: {
        start: number
        end: number
    }
}

If you don't want to publish metrics, you can turn it off in the constructor configuration:

const Streamr = require('@streamr/sdk')

const streamr = new Streamr({
    ...
    metrics: false
})

If you want to use custom stream and/or reporting periods, you can specify the details like this:

const Streamr = require('@streamr/sdk')
const streamr = new Streamr({
    ...
    metrics: {
        periods: [{
            duration: 3600000, // in milliseconds
            streamId: "my-metrics-stream.eth/hour"
        }]
    }
})
