    @@ -700,6 +700,31 @@ Flink metric types are mapped to Prometheus metric types as follows:
     
     All Flink metrics variables (see [List of all Variables](#list-of-all-variables)) are exported to Prometheus as labels. 
     
    +### PrometheusPushGateway (org.apache.flink.metrics.prometheus.PrometheusPushGatewayReporter)
    +
    +In order to use this reporter you must copy `/opt/flink-metrics-prometheus-{{site.version}}.jar` into the `/lib` folder
    +of your Flink distribution.
    +
    +Parameters:
    +
    +- `host` - the PushGateway server host
    +- `port` - the PushGateway server port
    +- `prefix` - (optional) the prefix is used to compose the jobName, defaults to `flink`. The jobName is used to distinguish different flink clusters
    +
    +Example configuration:
    +
    +{% highlight yaml %}
    +
    +metrics.reporter.promgateway.class: org.apache.flink.metrics.prometheus.PrometheusPushGatewayReporter
    +metrics.reporter.promgateway.host: localhost
    +metrics.reporter.promgateway.port: 9091
    +metrics.reporter.promgateway.prefix: flink
    +
    +{% endhighlight %}
    +
    +PrometheusPushGatewayReporter push metrics to a [Pushgateway](https://github.com/prometheus/pushgateway). The Pushgateway then exposes 
    +these metrics to Prometheus. The working mechanism is different from PrometheusReporter (see [PrometheusReporter](#prometheus-orgapacheflinkmetricsprometheusprometheusreporter)).

    I will remove the second sentence as it provides no value, and instead introduce a link tot he prometheus documentation for pushgateway use-cases.
