sloth Support OpenSLO v1

I have a openslo/v1 spec file that is valid:

$ oslo validate -f ./hung_operations.yaml
Valid!

but sloth can't read it:

$ sloth generate -i hung_operations.yaml
INFO[0000] SLI plugins loaded                            plugins=0 svc=storage.FileSLIPlugin version=0.12.0 window=30d
INFO[0000] SLO period windows loaded                     svc=alert.WindowsRepo version=0.12.0 window=30d windows=2
error: "generate" command failed: invalid spec, could not load with any of the supported spec types%

Because Sloth currently only supports the v1alpha https://github.com/slok/sloth/blob/ff0dced6a3ee6814e8954d25c8ebb1021050ce3b/pkg/common/model/slo_prometheus.go#L72

Right, this issue is to request support for v1 to be added.

Is this something that will be added over time? Any update on this? If not, then I know I should use the non-openslo spec going forward

Hi 👋

I don't know if it will be supported in the future. Currently its not a priority nor in the short-term roadmap, sloth has new features that can't be supported by OpenSLO standard (like the SLO plugins).

My recommendation is to use the sloth spec.

Thanks for the update @slok, I see the differences and how it would be difficult to align the two. I've switched my config to sloth native definitions. Thanks for the great product 👍🏽
