We run “mntr” periodically and occasionally saw high values of zk_max_latency in 10+s or even 30+s.
When that happened: * number of alive connection is less than 150 * “fsync” does not seem to be an issue as only few reported with time less than 3s * number of outstanding requests less than 10 or even 0 It could be related to I/O or network, what are the best ways to look into this issue? any command recommended to capture statistics for analysis? Thanks!
