Thanks @ethervoid 

> E0713 12:23:08.211652    32 redis_cmd.cc:3533] checkWALBoundary with sequence: 58132926866, but GetWALIter return older sequence: 58132926860

This log entry means the replica's replication offset was too old, so it would fully sync with master DB. The exporter can't fetch the metrics that happens at the same time point, so I guess that it may be caused by high network bandwidth and CPU usage when doing full sync.
