Configure anomaly detection to exclude metrics for CIs that are in maintenance mode from
model learning.

You can change the settings of system properties to include or exclude metric data for CIs
while they are in maintenance mode.

When the system property [sa.model_learner.maint_event_record_history_enabled](https://www.servicenow.com/docs/RdxWagLh~X3f5W4UApGYAg "Several types of components are installed with activation of the Metric Intelligence (com.snc.sa.metric) plugin, including tables, scheduled jobs, and properties.") is set to true (default),
Metric Intelligence stores historical information about the times CIs enter and exit
maintenance mode. When the system property [sa_metric.maint_exclusion](https://www.servicenow.com/docs/RdxWagLh~X3f5W4UApGYAg "Several types of components are installed with activation of the Metric Intelligence (com.snc.sa.metric) plugin, including tables, scheduled jobs, and properties.") is set to true (default), metrics from CIs that are in
maintenance mode are excluded from model learning.
