New Features
Add a client for sending stats to prometheus
integrationtest.prometheusstats.main,
ocean.util.app.DaemonApp,
ocean.util.prometheus.collector.Collector,
ocean.util.prometheus.collector.CollectorRegistry,
ocean.util.prometheus.collector.StatFormatter,
ocean.util.prometheus.server.PrometheusHandler,
ocean.util.prometheus.server.PrometheusListener
Prometheus sends HTTP GET requests to an application at /metrics endpoint to
pull stats from it. This feature adds a listener for these requests, and a
handler to response with stats to prometheus.
Also introduced here are classes that interface between the handler and a
client application, such that the handler is able to invoke callbacks that
collect stats from the client application upon receiving requests from
prometheus.
The DaemonApp class now has two functions, namely, collectSystemStats and
collectGCStats, to allow existing implementations to initially incorporate
system and GC stats into Prometheus' stat collection with ease.
In general, the steps to start stat collection using Prometheus would be:
a. Create a `CollectorRegistry` instance with all the delegates, fetching
your desired stats.
b. Create a `PrometheusListener` instance with your desired socket address
and the `CollectorRegistry` instance (created in step a).
c. Register the `PrometheusListener` instance (created in step b) with your
epoll dispatcher, using the `PrometheusListener.registerEventHandling`
method.
To stop the listener, the method PrometheusListener.shutdown should suffice
(along with de-registering from epoll, if needed).
For a detailed and functional example, please refer to the system test module,
integrationtest.prometheusstats.main and the unittest in module
ocean.util.prometheus.server.PrometheusListener.
