We are monitoring our Aerospike cluster through metrics(collectd plugin) and see ‘rw_err_ack_nomatch’ errors frequently.
Metrics docs suggest that it’s “Number of prole write acknowledgments started but went amiss/have mismatched information”.
The meaning is not clear to me. I have replication factor of 3. Does this mean that while writing, it couldn’t be successfully written to replicas ?
Does this indicate write loss or just acks or any inconsistency between master and replica nodes ? Does it point to flaky network or some problem in my config ? Should I be worried about it? Also, All my err_write* metrics have zero values.
Can someone please help in clarifying about this metrics and should I be worried about this metrics ? Thanks!
