To optimize the evaluation of event conditions, data monitors must be of the event or correlation type and must be using a filter, because event conditions are defined in the filter. Filters are used not only in data monitors but also in other resources, for example, active channels and query viewers. However, event conditions in filters are only evaluated and optimized in the context of the data monitors that use these filters. The filters themselves are not altered by the evaluation.
Refer to Creating or Editing a Filter for more information.
Note: A data monitor can use one or more filters. In this case, all filters being used by the data monitor will be optimized in memory.
