This version is coming with internal changes, improvement and bug fixes.

Here is the changelog of version 2.8:

  • Simplify and fix startup scripts
  • Change ownership of cron script to avoid issue with logs
  • Check if HTML5 localStorage is activated and warn user is not
  • Improve upgradable packages detection

Installation of the repository and upgrade to 2.8

One of the major improvement of this version is the activation of a debian repository directly into github. This repository will make installation and update of RPi-Monitor accessible with the commands apt-get or aptitude.

To use this repository follow the instruction bellow:

Activate https transport for apt and add certificate authority:

    sudo apt-get install apt-transport-https ca-certificates

Execute the following command to add RPi-Monitor into your list of repository:

    sudo wget -O /etc/apt/sources.list.d/rpimonitor.list

To install RPi-Monitor, execute the following command: 

    sudo apt-get update
    sudo apt-get install rpimonitor

To upgrade RPi-Monitor, execute the following command:

    sudo apt-get update
    sudo apt-get upgrade

Note: The package is not signed, it will be require to accept installation of unauthenticated package.

After installation you should excute the following command to update information about upgradable packages:

  sudo /usr/share/rpimonitor/scripts/

Manual installation is still working. Refer to RPi-Monitor Installation page for explaination.

Configuration indexes unicity simplification

Doing customization of RPi-Monitor could become quite complex when you have many data to monitor and doing change, reorder on these configuration files could become a nightmare if you manage multiple files. The reason of this complixity was the unicity constraint of indexes over all configuration file.

This version is removing this constraint. This requirement is now only applicable per file.

This is meaning that when you need to add a new measurment point, you just have to create a new file and add the configuration lines as you would do for the first configuration file. You don't have to care about the existing indexes previously used.

Removing this contrainst open the field of configuration possibilities. A new keyword have been added: include which can be used as follow:


When RPi-Monitor will detect the include keyword, it will add the file to the list of configuration files to be loaded. In other words, the configuration files to load will be appended to the list of file to be loaded wherever is located of include keywork into a file.
If you want to keep the control of the order of information display, it will then be recommanded to create one file per information and the create a file containing a list of configuration file to load. data.conf is now looking like that:


Customise menu logo, title and page title

This new function allow to define a custom logo, custome title and add the hostname of the machine int the title of the browser.

Here are the configuration lines used by default:'img/avatar.png''XB-Monitor  <sub>('+data.hostname+')</sub>''XB-Monitor ('+data.hostname+')'

data.hostname is a value automatically extracted by RPi-Monitor. It is not needed to add a configuration to do such a thing.

The file avatar.png has been added into /usr/share/rpimonitor/web/img/.

Here is the result:

Inside Firefox title bar and tab, the title has been changed and hostmane has been added between parentheses.
Inside RPi-Monitor menu bar, le logo and the title have been changed and hostmane has been added between parentheses.

Badges function to reflect status

This version of RPi-Monitor introduce a new function dedicated to show the status of a service. This function is named "Badge". This function is very similar to the function "Label" introduced in version 2.7. To use this function,you can refer to the article Rpi-Monitor: Use Label to show server status and replace Label by Badge.

About shellinabox

Shellinabox allow you to access to the shell of your Raspberry Pi through a web interface. You can activate this feature into the configuration dialog box.

By default, the link is set to '''/shellinabox'''. When RPi-Monitor will recieve this request, it will automatically do a redirect to http://RPiIpAddress:4200/. You can modify this address to point to your shellinabox address. This address is used inside the iframe of shellinabox page.


RPi-Monitor is fully configurable so if the displayed information doesn't match you need, customize it.
Everything display in status pages or in statistics pages can be modified, tuned and customized to your needs.

To see how to customize it, use the command
    man rpimonitord
    man rpimonitord.conf

Man pages are also available in the wiki.

To define the configuration you can use RPi-Monitor Interactive Configuration Helper whit the command:
    rpimonitord -i

You will find some examples of customization in RPi-Monitor articles.


Once RPi-Monitor is configured as you wished, browse http://RPiIpAddress:8888/ to access to the web interface.

Note: The graphs rendering may have strange behavior on Google-Chrome on Windows while it works fine on Linux. Internet Explorer is even not able to display statistics, it is then advised to use Firefox on Windows or better... switch to Linux! ;-).
