Are there any best practices for CB monitoring that I can reference? One of the metrics I'm trying to determine is the size of the working set (compared to total RAM available for bucket), but this data is split up into a number of separate items, eg. user data, replicas, metadata. I'm not 100% which of the metrics on the cbstats docs page (
http://www.couchbase.com/docs/couchbase-manual-1.8/cbstats-all-bucket-info.html) relate to which of these items. ep_kv_size is apparently the user data size, but on the node stats page in the UI it lists ep_ht_memory, yet I can't find this value in the output of cbstats.
Can anyone tell me what I should look at to get the size of the working set?
Thanks,
Guy
