健康指示器 "监视器堆使用率"（"db2.mon_heap_util"）突破了在 "实例"
"DB2" 上带有值 "206 %" 的 "95 %" 的 "上限"
警报阈值。
Basically the monitor heap is used to store information that used in snapshot and etc... to capture system status.
So usually it won't be a big issue because it won't affect any existing behivior of the system.
然后，让我查看一下此参数的当前值：
get dbm cfg
发现 mon_heap_sz 竞然只有 32 Pages，
update dbm cfg using mon_heap_sz 4096
