Hi Lin, My 2 cents:- 1. The Perf Dump Stats for the Ceph Dameons can be collected via the admin socket itself. 2. Since all the Daemons themselves run in a distributed fashion, you would need to collect it at per host/daemon level. 3. There is no performance impact collecting every 60 seconds, only exception being the phases when the asok(admin socket is not available), during initial boot. 4. The more tricky part is to aggregate all the stats and make sense of what is going overall in the cluster
