error: "generate" command failed: invalid spec, could not load with any of the supported spec types about sloth HOT 4 CLOSED

Hi @joegalley!

I would say that is not related to the plugins. OpenSLO spec doesn't support Sloth's SLI plugin system.

Check this issue #135 Somebody had the same issue and I couldn't reproduce it, I could use Sloth on windows correctly.

Check if the downloaded spec is not empty, or you don't have permission to load it.

Regading whats an SLI plugin. Plugins are a way of abstracting the SLI (query) from the user, like when in programming you use a library and you don't need to know the underneath implementation. This would be something similar but for SLIs.

For example one person/team creates the plugin, another person/team uses it by referencing the plugin. E.g:

Normally you could set this on the spec:

#...
    sli:
      events:
        error_query: sum(rate(http_request_duration_seconds_count{job="myservice",code=~"(5..|429)"}[{{.window}}]))
        total_query: sum(rate(http_request_duration_seconds_count{job="myservice"}[{{.window}}]))
#...

Having a plugin for that SLI. you could use like this:

#...
    sli:
      plugin:
        id: "my-company/services/availability"
#...

This abstracts the queries and gains things like:

• Could create standards across the company.
• Have a repository/index of plugins for common used applications
• Boost best practices on queries by having people with a lot of Prometheus knowledge maintain the plugins
• Centralizes the SLI queries (update in one place, deliver to all the plugin users).

Best.

Hello

I encounter the same issue on windows. The problem is simply related to carriage return encoding:

• with CRLF it fails
• with LF it's OK

I have not digged into the code, but it might be possible to fix that.
