check-stackdriver-go's Issues

"Group by" feature

Hi,

I have a metric which contains multiple metrics, as shown by the -v option.

~$ ./check_stackdriver -g 'my-project' -a 'my.json' -m 'logging.googleapis.com/user/my-custom-metric -v'

type:"logging.googleapis.com/user/my-custom-metric" labels:{key:"Status" value:"200"} labels:{key:"log" value:"nginx-logs"}
type:"gce_instance" labels:{key:"instance_id" value:"126267197000229410"} labels:{key:"project_id" value:"my-project"} labels:{key:"zone" value:"europe-west3-a"}

type:"logging.googleapis.com/user/my-custom-metric" labels:{key:"Status" value:"500"} labels:{key:"log" value:"nginx-logs"}
type:"gce_instance" labels:{key:"instance_id" value:"126267197000229410"} labels:{key:"project_id" value:"my-project"} labels:{key:"zone" value:"europe-west3-a"}

Is it possible to add the "group_by" function, for instance, to group by metric.label.Status? So then, I could alert based on current 200 status, for instance, to be less than a specified value throughout ALL the instances.

Thanks
