The diagnostics commands are triggered remotely via balenaCloud. Navigate to
https://dashboard.balena-cloud.com/devices/{{UUID}}/diagnostics to run and view the output. Only
multicontainer-capable devices (balenaOS v2.12.0 or higher)
are fully supported and tested (see balena-io-modules#126 for more discussion).
To add more checks, first define the check function and then add the function to the run_checks() function in checks.sh.
Checks should be fail-first, and defensive when possible. If a failing check will emit stderr, it is better to redirect
away rather than allowing it to propagate through. All numerics should be declared as such if possible.
Additionally, all checks should be documented in diagnostics.md.
To add more commands, simply add the command to the commands array in diagnose.sh.
