+# Install and setup instructions for the RPI Docker Monitor
+
+## Introduction
+
+A monitoring solution for Docker hosts and containers with [Prometheus](https://prometheus.io/), [Grafana](http://grafana.org/), [cAdvisor](https://github.com/google/cadvisor), [NodeExporter](https://github.com/prometheus/node_exporter).

+
+# Installation
+
+## Pre-Installation Steps
+
+First SSH into your Pi and there is one thing we need to do before we get cracking. We need to enable `c-groups` so the stack will work out of the box. To do this you need to modify the configuration file `cmdline.txt`:  This is stored in various locations depending on your OS.  
+
+### Pi OS
+```
+sudo nano /boot/cmdline.txt
+```
+
+### Ubuntu OS
+```
+sudo nano /boot/firmware/cmdline.txt
+```
+
+### All OS's add the following options to the begin of the line:
+
+```
+cgroup_enable=memory cgroup_memory=1
+```
+
+### Now save the file in your editor and reboot:
+
+```
+sudo reboot
+```
+
+### Confirm that c-groups are enabled
+
+```
+cat /proc/cgroups
+```
+
+You should see output something like this.
+
+```
+#subsys_name    hierarchy       num_cgroups     enabled
+cpuset  9       15      1
+cpu     7       69      1
+cpuacct 7       69      1
+blkio   8       69      1
+memory  11      158     1
+devices 3       69      1
+freezer 5       16      1
+net_cls 2       15      1
+perf_event      6       15      1
+net_prio        2       15      1
+pids    4       76      1
+rdma    10      1       1
+```
+
+The numbers aren't really important what is important is that you see memory in the list if you don't confirm you have put it in the correct file.  Don't go on until you get this working.
+
+## Folder Setup Script
+
+First thing we need to do is setup the folder structure and install some files that need to be in place for everything to work correctly.  
+
+Run the following script
+```
+sudo ./rpi_docker_monitor.sh
+```
+
+Your output should look something like this
+
+```
+# sudo ./rpi_docker_monitor.sh

+
+### This Step is now complete go to the next step.
+<br><br>
+## Install the App Template.<br>
+
+[comment]: # (FixMe)
+![alt text](https://raw.githubusercontent.com/rmiddle/pi-hosted/docker_monitor/docs/images/rpi_docker_monitor-AppTemplatesList.png)
+
+Goto App Templates and install "Raspberry Pi Docker Monitor"
+
+The default settings should all be good so **Deploy the Stack**
+<br><br>
+
+## Setup Grafana
+
+Navigate to Grafana `http://<host-ip>:3000` and login with user ***admin*** password ***admin***. You can change the credentials in the template file or by supplying the `ADMIN_USER` and `ADMIN_PASSWORD` environment variables inside the container monitoring-prometheus. 
+
+```yaml
+GF_SECURITY_ADMIN_USER=admin
+GF_SECURITY_ADMIN_PASSWORD=changeme
+GF_USERS_ALLOW_SIGN_UP=false
+```
+
+### Setup Prometheus as the default data source.
+ 
+```
+Grafana > Configuration > Data Sources > Prometheus
+```
+**It is important that you set the URL to http://monitoring-prometheus:9090/**<br><br>
+
+![image](https://raw.githubusercontent.com/rmiddle/pi-hosted/docker_monitor/docs/images/rpi_docker_monitor-DataSource.png)
+
+### Setup the Dashboard
+Grafana is not preconfigured with dashboard, so you have to import it from the  [json](https://github.com/oijkn/Docker-Raspberry-PI-Monitoring/blob/main/grafana/dashboard_by_oijkn.json) file.
+
+```
+Grafana > + > Import 
+```
+
+![image](https://raw.githubusercontent.com/rmiddle/pi-hosted/docker_monitor/docs/images/rpi_docker_monitor-Dashboard-Menu-Import.png)
+
+Now we open the [json](https://github.com/oijkn/Docker-Raspberry-PI-Monitoring/blob/main/grafana/dashboard_by_oijkn.json) file and Click on the "raw" button to copy the content from the json file.
+
+(!["raw" button](https://raw.githubusercontent.com/rmiddle/pi-hosted/docker_monitor/docs/images/rpi_docker_monitor-Raw.png))
+
+
+ Once copied into the bigger of the 2 boxes Click Load.
+
+![image](https://raw.githubusercontent.com/rmiddle/pi-hosted/docker_monitor/docs/images/rpi_docker_monitor-Dashboard-Import.png)
+
+
+Now we can display the dashboard
+
+```
+Grafana > Dashboard > Manage
+```
+![image](https://raw.githubusercontent.com/rmiddle/pi-hosted/docker_monitor/docs/images/rpi_docker_monitor-Menu-Dashboard-Manage.png)
+
+There should be just the one item list.  Select "Docker and OS Metrics" from the list and you should see the dashboard listed below.

+
+
+> Hint: Well the Dashboard is displayed you can select your profile > Preferences and change the default Dashboard to the new Dashboard you just create and it will always display the new Dashboad when you login.
