Methods

addAppServicePath

  • addAppServicePath(bridge: Bridge): void

addCollector

  • addCollector(func: CollectorFunction): void
  • Adds a new collector function. These collector functions are run whenever the /metrics page is about to be generated, allowing code to update values of gauges.

    Parameters

    • func: CollectorFunction

      A new collector function. This function is passed no arguments and is not expected to return anything. It runs purely to have a side-effect on previously registered gauges.

    Returns void

addCounter

  • addCounter(opts: CounterOpts): Counter<string>

addGauge

  • addGauge(opts: GagueOpts): Gauge<string>

addTimer

  • addTimer(opts: HistogramOpts): Histogram<string>
  • Adds a new timer metric, represented by a prometheus Histogram.

    Parameters

    • opts: HistogramOpts

      Options

    Returns Histogram<string>

    A histogram metric. Once created, the value of this metric can be incremented with the startTimer method.

incCounter

  • incCounter(name: string, labels: {}): void
  • Increments the value of a counter metric

    param{string}

    name The name the metric was previously registered as.

    param{object}

    labels Optional object containing additional label values.

    Parameters

    • name: string
    • labels: {}
      • [label: string]: string

    Returns void

  • refresh(): Promise<void>

registerBridgeGauges

registerMatrixSdkMetrics

  • registerMatrixSdkMetrics(appservice: Appservice): void
  • Registers some exported metrics that relate to operations of the embedded matrix-js-sdk. In particular, a metric is added that counts the number of calls to client API endpoints made by the client library.

    Parameters

    • appservice: Appservice

    Returns void

startTimer

  • startTimer(name: string, labels: {}): () => void
  • Begins a new timer observation for a timer metric.

    param{string}

    name The name the metric was previously registered as.

    param{object}

    labels Optional object containing additional label values.

    Parameters

    • name: string
    • labels: {}
      • [label: string]: string

    Returns () => void

    A function to be called to end the timer and report the observation.
