wrong nrpe exporter binary gets downloaded

[nishant-dash]

Enhancement Proposal

I deployed cos proxy from edge

cos-proxy-monitors  n/a      error       1  cos-proxy  edge      70  no       hook failed: "monitors-relation-joined"

and its in error on

FileNotFoundError: [Errno 2] No such file or directory: 'nrpe_exporter-amd64'

As a result of 883ede2
the only binary that gets downloaded is named nrpe_exporter-aarch64

# ls /var/lib/juju/agents/unit-cos-proxy-monitors-0/charm
LICENSE  README.md  dispatch  hooks  icon.svg  lib  manifest.yaml  metadata.yaml  nrpe_exporter-aarch64  revision  src  templates  vector  venv

Im not sure what the cleanest fix is given that https://github.com/canonical/nrpe_exporter/releases/tag/0.2.6 only has releases for arm64 and amd64 but not aarch64.

Perhaps you could release a binary for aarch64 and simplify the curl logic in charmcraft.yaml?

cos-proxy-operator/charmcraft.yaml

curl -L $URI -o nrpe_exporter-aarch64
