Feature Request: ARM Support

[espenaf]

Hi there

ARM support would be awesome

[julian7]

I can't test it myself. Do you think a simple cross-compilation would suffice?

[espenaf]

If you look at https://github.com/sensu/check-disk-usage or https://github.com/sensu/check-cpu-usage, these plugins have been setup with a way to publish arm5/6/7/64 based artifacts for the asset. Doing something similar will maybe work, and then I can test the new ARM built versions.

I've released v0.5.0 with ARM v7 and ARM64 support. Could you please have a look?

[espenaf]

The binaries worked just fine, tested on a cluster of 4 Raspberry Pi`s (3 and 4).

There is one small remaining issue with how the asset definition is being created, this was fixed in the check template in sensu/check-plugin-template#11:

Asset filters for ARM entities need to use entity.system.arch == 'arm' and entity.system.arm_version == X instead of entity.system.arch == 'armX'.

Hmm the beauty of undoc features. While examples are full with arm_version mentions, it's not mentioned in system attributes.
Its definition is in core system type.

I have to take it back, as the asset yaml configuration is in GoShipDone's sensulib extension, but I hope I'll have some time during the weekend to implement this change.
