+title: Metrics with Prometheus
+---
+
+#### 0. Introduction
+
+This tutorial explains how to export open5gs metrics to Prometheus, which can in
+turn be used to visualize or export them to other systems such as Grafana or
+StatsD.
+
+When this method is used, any open5gs program exporting metrics becomes a
+Prometheus server, which is basically an HTTP server serving Prometheus data to
+the Prometheus scrapper.
+
+Note: Only open5gs-smfd supports exporting metrics so far, though other may
+hopefully follow soon.
+
+#### 1. Enable Prometheus support during build
+
+Open5GS programs use a generic internal API available in libogsmetrics. This
+library implements the API based on configuration passed during open5gs build
+time. By default, the library will be built using the `void` implementation,
+which is basically a NO-OP implementation.
+
+In order to use the Prometheus, the `prometheus` metrics implementation needs to
+be selected at build time:
+
+```
+meson configure -Dmetrics_impl=prometheus build
+```
+
+This will enable building the implementation under lib/metrics/prometheus/,
+which uses:
+
+* prometheus-client-c project (libprom): To generate the Prometheus expected
+  output format of the metrics
+* libmicrohttpd: To server the content generated by libprom as an HTTP server
+
+The `prometheus-client-c` project is not currently well maintained, and uses a
+weird mixture of build systems, which makes it difficult to make it available in
+most Linux distributions. As a result, a fork of the project is available under
+Open5GS GitHub namespace, with an extra patch applied making it possible to
+include it as a subproject, which will be fetched and built automatically when
+building the prometheus libmetrics implementation.
+
+#### 2. Configuring for runtime
+
+By default the created Prometheus HTTP server will be listening on `0.0.0.0`
+port `9090`.
+This can be configured under the following config file options:
+
+```
+#
+# metrics:
+#
+#  <Metrics Server>
+#
+#  o Metrics Server(http://<any address>:9090)
+#    metrics:
+#      addr: 0.0.0.0
+#      port: 9090
+#
+metrics:
+    addr: 0.0.0.0
+    port: 9090
+```
+
+Note: You may want to change the default IP address or port if you are running
+the Prometheus scrapper in the same host, since it will also spawn its own
+Prometheus server also in port 9090, which will collide.
+
+#### 3. Manual visualization
+
+Simply open the web browser at the following URL (changing IP address and port
+as configured in previous section):
+```
+http://127.0.0.1:9090/metrics
+```
+
+Note: URL `metrics/` (with a slash at the end) will not work.
+
+You should see some output similar to this one below:
+```
+# HELP ues_active Active User Equipments
+# TYPE ues_active gauge
+ues_active 2
+
+# HELP process_max_fds Maximum number of open file descriptors.
+# TYPE process_max_fds gauge
+process_max_fds 1024
+
+# HELP process_virtual_memory_max_bytes Maximum amount of virtual memory available in bytes.
+# TYPE process_virtual_memory_max_bytes gauge
+process_virtual_memory_max_bytes -1
+
+# HELP process_cpu_seconds_total Total user and system CPU time spent in seconds.
+# TYPE process_cpu_seconds_total gauge
+process_cpu_seconds_total 0
+
+# HELP process_virtual_memory_bytes Virtual memory size in bytes.
+# TYPE process_virtual_memory_bytes gauge
+process_virtual_memory_bytes 3156643840
+
+# HELP process_start_time_seconds Start time of the process since unix epoch in seconds.
+# TYPE process_start_time_seconds gauge
+process_start_time_seconds 402433
+
+# HELP process_open_fds Number of open file descriptors.
+# TYPE process_open_fds gauge
+process_open_fds 23
+```
+
+#### 3. Integration with Prometheus scrapper
+
+Sample Prometheus scrapper configuration (`~/prometheus.yml`):
+```
+global:
+  scrape_interval: 10s
+
+scrape_configs:
+  - job_name: open5gs-smfd
+    static_configs:
+      - targets: ["192.168.1.140:9091"]
+```
+
+Where `192.168.1.140:9091` is the IP address and port where `open5gs-smfd` is
+serving its metrics, as configured in above sections.
+
+The Prometheus scrapper can be easily started from a docker container:
+```
+docker run -p 9090:9090 -v  /prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
+```
+
+Then open your browser to be able to visualize the data: `http://localhost:9090/graph`
