I haven't used this provider before, but isn't it too much to assume all numeric properties are always metrics? Isn't there a case where I would like to track just a normal numeric property?

[anthonychu]

@lunks Good point. I've thought about this and one idea was to provide a setting to specify a suffix to use to indicate a property is a metric. For example, if the suffix is "metric"...

<button analytics-on analytics-category="Commands"  
    analytics-label="Button4 label" 
    analytics-numeric-value-metric="1">Button 4</button>

The provider will strip off the suffix before sending to Azure. And maybe by default the suffix is null and it'll automatically send numerics as metrics.

Do you have any other ideas to approach this? Thanks.

I think it becomes too verbose, but being vendor-specific, I don't really care much. If you @anthonychu are ok with that, it's cool. I don't see any other complaining here, so :)

We are in the process of moving all plugins off the core and into their own repo (see #377) so no longer is accepted PRs for plugins. Instead, I'd appreciate if you create a repo for this plugin on your side and make sure to comply with the plugin contribution rules.

Once you have everything ready, let us know and if everything's right we can adopt the plugin into the Angulartics org.

Thank you!
