Hello. This is Rui
Version: 4.5.1-2844 Community Edition (build-284)
Bucket count: 3
Number of nodes: 6
mem_low_wat from 85%, 75% to 75%, 55%.
I also clicked on the bucket to see that it was applied on the monitoring page. (Check memory size)
The value of
ep_exp_pager_time was also changed to 10 minutes (600).
However, memory is used in excess of the
mem_high_wat value, but there is no operation at the expiry operation time.
I have a four question.
Is there a water mark trigger?
I’d like to know exactly how above works.
Is there a manual or automated way to return the bucket memory?
When couchbase returns memory, which monitoring metrics should I check?
