+# Autoscaling Application
+The auto-scaling app uses monitoring data to decide when to scale a service up/down.
+
+It is treated as an application rather than yet another
+service because it offers only a GUI front-end; it is not
+modelled as a service that other services can build upon.
+
+#How to
+
+Ensure that the CORD config is installed and then run:
+
+`python xos_auto_scaling_app.py`
+
+This command will start the autoscaling application and start REST server on 9991 port.
+
+## To verify the autoscaling application:
+1) Login to cloudlab compute nodes <br/>
+2) On each compute node, open /etc/ceilometer/pipeline.yaml file<br/>
+3) Change the polling interval for "cpu_source" meters from 600 to poll interval period that u wish (eg. 60) as shown below.<br/>
+From:
+```
+    - name: cpu_source
+      interval: 600
+      meters:
+          - "cpu"
+      sinks:
+          - cpu_sink
+```
+
+To:
+```
+    - name: cpu_source
+      interval: 60
+      meters:
+          - "cpu"
+      sinks:
+          - cpu_sink
+```
+3b) Also ensure the publisher in "cpu_sink" contains the following URL "udp://"IP of Ceilometer PUB-SUB":5004" as shown below.<br/>
+```
+    - name: cpu_sink
+      transformers:
+          - name: "rate_of_change"
+            parameters:
+                target:
+                    name: "cpu_util"
+                    unit: "%"
+                    type: "gauge"
+                    scale: "100.0 / (10**9 * (resource_metadata.cpu_number or 1))"
+      publishers:
+          - notifier://
+```
+
+To:
+```
+    - name: cpu_sink
+      transformers:
+          - name: "rate_of_change"
+            parameters:
+                target:
+                    name: "cpu_util"
+                    unit: "%"
+                    type: "gauge"
+                    scale: "100.0 / (10**9 * (resource_metadata.cpu_number or 1))"
+      publishers:
+          - notifier://
+          - udp://10.11.10.1:5004
+```
+4) sudo service ceilometer-agent-compute restart<br/>
+5) With this change, the autoscaling application should start receiving the CPU utilization samples every 60 seconds<br/>
+6) The REST API to retrieve the cpu utilization samples from autoscaling application: http://<app_ip>:9991/autoscaledata 
+
+## GUI (early development stage)
+
+To run this sample you need to have `nodejs >= 4.0` installed on your local system. You can get it [here](https://nodejs.org/en/)
+
+- Clone the repository locally
+- Open `xos-apps/auto-scale/gui/env/default` and change it to:
+```
+module.exports = {
+  host: 'http://<your.cord.installation.ip>:9991'
+}
+```
+- From `xos-apps/auto-scale/gui` run `npm start`
