Raspberry Pi monitor

Links

With Rpi-monitor you can monitor various aspects of your Raspberry Pi. The package has its own simple webserver. It works well for smaller screens (mobile phone) and history can be visualized with some graphs. If it still isn't to your liking it allows for some serious tinkering.

daemon.delay=60

sudo systemctl restart rpimonitor

Network monitoring

Uncomment all lines that are commented and comment the lines that contain the configuration message.

sudo nano /etc/rpimonitor/template/network.conf

Tweaking

Reduce main page width

Search for the file we know to contain style we want to change:

find / -name "rpimonitor.css" 2>/dev/null

1. changed width: 518px; into width: 300px;:
2. changed nowrap into normal:

sudo nano -l +63 /usr/share/rpimonitor/web/css/rpimonitor.css

.Text {
  float: left;
  font-family: Tahoma, Helvetica;
  font-size: 13px;
  line-height: 13px;
  padding-left: 30px;
  padding-right: 30px;
  padding-top: 15px;
  width: 300px; // 518px
  white-space: normal ; // nowrap;
}

Reduce graph width

Changed graph_width:"750px" into graph_width:"400px":

sudo nano -l +174 /usr/share/rpimonitor/web/js/rpimonitor.statistics.js

...
rrdflot_defaults={ graph_width:"400px",graph_height:"285px", scale_width:"350px", scale_height:"90px", use_rra:true, rra:active_rra };
...

Link from the main page directly to the corresponding graph

Modify the function Start() in "rpimonitor.statistics.js" to read a parameter 'graph':

sudo nano -l +26 /usr/share/rpimonitor/web/js/rpimonitor.statistics.js

// ...

function Start() {
  static = getData('static')
  graphconf = getData('statistics')

  //modified: read activestat from url graph parameter
  activestat = GetURLParameter('graph');
  if (activestat == null){
    activestat = localStorage.getItem('activestat') || 0;
  }

  // ... unchanged ...

  activePage = GetURLParameter('activePage');

  // ...
}

// ...

Then modify "uptime.conf" (graph=0) to include a link to the graph. Same for for "cpu.conf" (graph=1), "temperature.conf" (graph=2), etc:

sudo nano /etc/rpimonitor/template/uptime.conf

web.status.1.content.1.name=<a target=_blank href=statistics.html?graph=0>Uptime</a>
