Hi Chen, Storm's built-in metrics are actually task heartbeat stored at ZK, and these values are calculated from each task and task writes them to ZK via replacing (I mean overwrite). If worker is killed and restarted, all metrics for tasks in worker are reset to 0, and it overwrites previous values when first heartbeat from that worker is made This is a limitation of current metrics since we don't store it to any storages or centralized in-memory. We'd like to address it.
