-The first step of the tutorial will be to define the elements to monitor. 
-In the testing archive, we will be able to see the consumption of the docker container by the default.
-So feel free to skip directly to the [preparation part](#preparation) if you don't want to monitor a specific process.

-## Define elements to monitor
-
-!!! tip "Optionnal abstraction for fine-grain analysis"
-    This part is optionnal, it allows the definition of cgroups which can group chosen processes that make sense to you.  
-    If you skip it, the next steps will work against all current process grouped.
-
-PowerAPI being a monitoring tool for energy consumption, we can define logic grouping of elements to monitor.
-To do so we can use the Linux abstraction of [cGroups](https://www.redhat.com/sysadmin/cgroups-part-one).  
-Kernel supports 2 versions of cGroups : v1 and v2. 
-To know which one your kernel supports, you can run :
-```sh
-mount | grep '^cgroup' | awk '{print $1}' | uniq
-```
-
-*Both versions can be supported at the same time*.
-
-??? "Create a cGroup"
-    
-    In order to create a cGroup, you can use:  
-
-    - cgroup v1 : [this doc](https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v1/cgroups.html#usage-examples-and-syntax)  
-    - cgroup v2 : [this doc](https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html#mounting)  
-
-    
-    
-??? "Add processes to the group"
-    
-    Once the cgroup created, we need to fill it with processes to be monitored. 
-    To do so, you can use:  
-
-    - cgroup v1 : [this doc](https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v1/cgroups.html#attaching-processes).  
-    - cgroup v2 : [this doc](https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v1/cgroups.html#attaching-processes).

-    [stress-ng](https://wiki.ubuntu.com/Kernel/Reference/stress-ng) can be used to 
-    generate load on one's system. **Be carefull** as it can be configured to be quite agressive.
