### In-container integrating util to handle processes runtime
( with amd64 and riscv64 support )
`noxis` - monitoring util with special attention on ## Depends on
1) **Speed**
2) **Multiplatform** execution *(with `amd64` and `riscv64` **support**)*
3) **Smallness** and **Optimization**
It's **main tasks** are
- to manage the processes that occur inside the container or in the target system.
- collect data (metrics);
- monitor the availability of system files necessary for the operation of processes;
- check whether there is a connection between processes and services, where the information comes from or where it is sent.
