3. Installing the trace and debug tool on your target board[edit | edit source]
3.1. Using the STM32MPU Embedded Software distribution[edit | edit source]
netdata is installed by default and ready to be used with all STM32MPU Embedded Software Packages.
which netdata /usr/sbin/netdata
It is integrated in weston image distribution through meta-st package: meta-st/meta-st-openstlinux/recipes-st/packagegroups/packagegroup-framework-tools.bb.
RDEPENDS:packagegroup-framework-tools-ui = "\
${@bb.utils.contains('DISTRO_FEATURES', 'x11', 'xvinfo', , d)} \
${@bb.utils.contains('DISTRO_FEATURES', 'gplv3', 'glmark2', , d)} \
${@bb.utils.contains('DISTRO_FEATURES', 'gplv3', 'netdata', , d)} \
${@bb.utils.contains('DISTRO_FEATURES', 'gplv3', 'lmsensors-libsensors lmsensors-sensors', , d)} \

4. Getting started[edit | edit source]
netdata provides all monitoring information on a web page accessible at the IP address of the board.
It proposes a default web page, on port 19999. It is also possible to create a custom page.
4.1. netdata service[edit | edit source]
netdata is managed as a service. In OpenSTLinux distribution, it can be found under meta-st/meta-st-openstlinux/recipes-webadmin/netdata/netdata/netdata.service.
The following command allows to verify if the service is active and running on the target board:
systemctl | grep netdata
netdata.service loaded active running Netdata, Real-time performance monitoring
In case it is not running, the service can be started using the following command:
systemctl start netdata
It is recommended to stop the service when it is not needed any longer:
systemctl stop netdata
4.2. Generic netdata web page[edit | edit source]
On host PC browser, the generic netdata web page is found at address:
http://<ip_of_board>:19999
4.3. Customized netdata web page[edit | edit source]
Some customized web pages are proposed in OpenSTLinux environment to monitor some specific indicators following STM32MPU series: STM32MPxx Dashboard
The web page are proposed as example and could be adapted to the platform used.
