rpi-monitor

Raspberry Pi System Monitor

Install Requirements

$ sudo apt-get install curl 

Install rpi-monitor

$ curl https://raw.githubusercontent.com/oopsmonk/rpi-monitor/master/auto-install.sh > auto-install.sh && bash !#:3 && rm !#:3 

If no error occurred, you're ready to go!

Crontab Debug(Optional)

By default, the cron.log is disabled in Raspbian.
Enable crontab log for debug:

#Ubuntu 14.04
$ sudo vi /etc/rsyslog.d/50-default.conf
#Raspberry Pi
$ sudo vi /etc/rsyslog.conf

Find the line and uncomment it.

# cron.*                          /var/log/cron.log

Restart rsyslog :

$ sudo /etc/init.d/rsyslog restart  

Default Web Configuration(Optional)

In the beginning, RRD files are stored in rpi-monitor/rrds, we have to create symbolic links to rpi-monitor/web-server/data for web server.
The difference between rpi-monitor/rrds and rpi-monitor/web-server/data, first is original data generated by program and second is used by web server to draw graphic. Because of this design, we can choose which data want to present in the web pages, but the following are necessary in rpi-monitor/web-server/data:
cpustatus.rrd => CPU usage
meminfo.rrd => Memory usage
uptime.rrd => System uptime

• Add RRD files which want to show on web.
  Create symbolic links via ln -s command, it's linked from rpi-monitor/web-server/data to rpi-monitor/rrds(the original data).

    $ cd ./web-server/data/
    $ ln -s ../../rrds/cpustatus.rrd cpustatus.rrd  
    $ ln -s ../../rrds/meminfo.rrd meminfo.rrd
    $ ln -s ../../rrds/uptime.rrd uptime.rrd  
    ....
    $ ln -s ../../rrds/hdd-sda1.rrd hdd-sda1.rrd
  

  Here is an example :

    $ tree ./web-server/data/
    ./web-server/data/
    ├── cpustatus.rrd -> ../../rrds/cpustatus.rrd
    ├── hdd-sda1.rrd -> ../../rrds/hdd-sda1.rrd
    ├── hdd-sda2.rrd -> ../../rrds/hdd-sda2.rrd
    ├── interface-eth1.rrd -> ../../rrds/interface-eth1.rrd
    ├── interface-eth2.rrd -> ../../rrds/interface-eth2.rrd
    ├── meminfo.rrd -> ../../rrds/meminfo.rrd
    ├── mount-root.rrd -> ../../rrds/mount-root.rrd
    └── uptime.rrd -> ../../rrds/uptime.rrd
  

• Start web server

    $ ./web-server/rpi_monitor_web.py  
  

• Nginx web server setup
  If you want to access from the Internet, you can use Nginx. For more detail:
  Understanding Nginx HTTP Proxying, Load Balancing, Buffering, and Caching
  Nginx proxy_pass

    $ sudo apt-get install nginx  
    $ sudo vi /etc/nginx/sites-available/rpi-mointor.com
  
    server {
        listen 9000;
        server_name localhost;
        access_log /var/log/nginx/rpiMonitor_access.log;
        error_log /var/log/nginx/rpiMonitor_error.log;
        location / {
            proxy_pass http://127.0.0.1:9999;
        }
    }
