func MakeQueryCPIString

func MakeQueryCPIString(options common.MetricQueryOptions) (string, error)

MakeQueryCPIString constructs PromQL style query string based on @options.

@return "sum by (container_id, container_name, pod_uid, pod_namespace, pod_name, node) " + "(koordlet_container_cpi{cpi_field=\"cycles\"}) / " + "sum by (container_id, container_name, pod_uid, pod_namespace, pod_name, node) " + "(koordlet_container_cpi{cpi_field=\"instructions\"})"

where (container_id, container_name, pod_uid, pod_namespace, pod_name, node) is the PromSumByLabels slice {cpi_field=\"cycles\"} is the FilterLabels map koordlet_container_cpi is options.MetricName
