+Prometheus Statistics
+=====================
+
+Each contiv-agent exposes statistics in Prometheus format at port
+``9999`` by default. Exposed data is split into two groups: - ``/stats``
+provides statistics for VPP interfaces managed by contiv-agent
+Prometheus data is a set of counters with labels. For each interface,
+the following counters are exposed: \* *inPackets* \* *outPackets* \*
+*inBytes* \* *outBytes* \* *ipv4Packets* \* *ipv6Packets* \*
+*outErrorPackets* \* *dropPackets* \* *inMissPackets* \*
+*inNobufPackets* \* *puntPackets*
+
+Labels let you add additional information to a counter. The
+*interfaceName* and *node* labels are specified for all counters. If an
+interface is associated with a particular pod, then the *podName* and
+*podNamespace* labels are also specified for its counters; otherwise, a
+placeholder value (``--``) is used (for example, for node interconnect
+interfaces). - ``/metrics`` provides general go runtime statistics
+
+To access Prometheus stats of a node you can use
+``curl localhost:9999/stats`` from the node. The output of contiv-agent
+running at k8s master node looks similar to the following:
+
+::
+
+ $ curl localhost:9999/stats

+
+In order to browse stats in web UI Prometheus, it must be started
+locally by following the information in the `Prometheus Getting Started
+Guide <https://prometheus.io/docs/prometheus/latest/getting_started/>`__.
+
+If you start Prometheus on a node, the following sample config can be
+used:
+
+.. code:: yaml
+
+ global:
+ scrape_interval: 15s
+
+ scrape_configs:
+ - job_name: 'contiv_stats'
+ metrics_path: '/stats'
+ static_configs:
+ - targets: ['localhost:9999']
+ - job_name: 'contiv_agent'
+ # metrics_path defaults to '/metrics'
+ static_configs:
+ - targets: ['localhost:9999']
+
+Once Prometheus is started with the specified config, you should be able
+access its web UI at ``localhost:9090``.
+
+::
+
+ tester@dev:~/Downloads/prometheus-2.1.0.linux-amd64$ ./prometheus --config.file=config.yml
+
+If security features are enabled for the HTTP endpoint, then the config
+must be adjusted:
+
+.. code:: yaml
+
+ - job_name: 'contiv_secured'
+
+ scheme: https
+ basic_auth:
+ username: user
+ password: pass
+ metrics_path: /stats
+ tls_config:
+ insecure_skip_verify: true
+ # CA certificate to validate API server certificate with.
+ #[ ca_file: <filename> ]
+ static_configs:
+ - targets: ['localhost:9191']
