 [NOTE] 
 =====
 Be mindful of the following:
+
 * Rule actions are not activated during manual runs. 
 * Except for threshold rules, duplicate alerts aren't created if you manually run a rule during a time range that was already covered by a scheduled run.
 * Manual runs are executed with low priority and limited concurrency, meaning they might take longer to complete. This can be especially apparent for rules requiring multiple executions.
