 # Prometheus Support
 
 ## Development
+AWX comes with an example prometheus container and make target.  To use it:
 
-Starting a Prometheus container.
+1.  Edit `tools/prometheus/prometheus.yml` and update the `basic_auth` section
-
+    to specify a valid user/password for an AWX user you've created.
-    docker run --net=tools_default --link=tools_awx_1:awxweb --volume <FULL_PATH>/prometheus.yml:/prometheus.yml --name prometheus -d  -p 127.0.0.1:9090:9090 prom/prometheus --web.enable-lifecycle --config.file=/prometheus.yml
+    Alternatively, you can provide an OAuth2 token (which can be generated at
-
+    `/api/v2/users/N/personal_tokens/`).
-Example Prometheus config.
+2.  Start the Prometheus container:
-
+    `make prometheus`
-	# prometheus.yml
-	# my global config
-	global:
-	  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
-	  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
-		# scrape_timeout is set to the global default (10s).
-
-	# Alertmanager configuration
-	alerting:
-	  alertmanagers:
-	  - static_configs:
-		- targets:
-			# - alertmanager:9093
-
-	# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
-	rule_files:
-		# - "first_rules.yml"
-		# - "second_rules.yml"
-
-
-	# A scrape configuration containing exactly one endpoint to scrape:
-	# Here it's Prometheus itself.
-	scrape_configs:
-	  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
-	  - job_name: 'prometheus'
-		  # metrics_path defaults to '/metrics'
-		  # scheme defaults to 'http'.
-		static_configs:
-		- targets: ['localhost:9090']
-
-	  - job_name: 'awx'
-		tls_config:
-		  insecure_skip_verify: True
-		metrics_path: /api/v2/metrics
-		scrape_interval: 5s
-		scheme: http
-		params:
