An aggregate rollup monitor is made up of a series of child monitors. When you create an aggregate rollup monitor, one of the important tasks is to determine the state of the aggregate relative to the states of the child monitors.
You can configure the state of an aggregate rollup monitor to reflect either the worst-case or best-case state of the child monitors.
In the worst-case scenario, the state of the aggregate matches the least healthy state of any of the child monitors. If only one child monitor is unhealthy, the aggregate will be unhealthy.
In the best-case scenario, the state of the aggregate reflects the best state of any of the child monitors. The aggregate is healthy if at least one of the child monitors remains healthy. Only when all of the child monitors are in an unhealthy state will the health state of the aggregate change to unhealthy.
