Sridhar Seshasayee	2019-12-11 03:57:10 UTC	Doc Text		Feature: A new configurable option called 'mon_memory_target' is introduced to set the target amount of bytes for monitor memory usage. This specifies the amount of memory to allocate and manage using the priority cache tuner for the associated MON caches. This config option is changeable at runtime. The default value of 'mon_memory_target' is set to 2 GiB and may be changed during runtime with: ceph config set global mon_memory_target <size> Reason: Prior to the enhancement it was found that as a cluster scaled, the MON specific RSS usage exceeded the limits that was set using 'mon_osd_cache_size' leading to issues. Result: This allows for improved management of memory allocated to the monitor caches and keeps the usage within specified limits.
