Detecting imbalances in data traffic for distributed data centers is described. A distributed data center system can obtain a set of data samples corresponding to respective data traffic at data centers, the respective data traffic based on data associated with an application. The distributed data center system can generate subsets of weight-transformed data samples associated with respective intervals of time. The distributed data center system can generate respective indices associated with the subsets of weight-transformed data samples. The indices can be representative of a data traffic balance at the data centers. The distributed data center system can transmit a message indicating an index failing to satisfy a threshold value, the index being associated with at least one subset of weight-transformed data samples.
