Set up the scope and condition

Tell mPulse where and how to look for potential performance issues. Use rule expression attributes to form the event condition that triggers the alert. Give mPulse a time window to watch for the event.

How to

  1. In the Specify Alert Details dialog, under Choose a Data Event, select Data Event.
  2. Select the app or domain that you want to track the event for.
  3. Select either All or Any.
    Think of these as logical operations. All is equal to and. All tells mPulse to trigger the alert when the criteria (in succession) meet the condition. Any is equal to or. Any tells mPulse to trigger the alert when one or more of the criteria meet the condition.
  4. Select either Timer or Metric, then define the alert condition.
    For Timer:
    1. Select an mPulse built-in timer, such as Time to Visually Ready, or a custom timer.
    2. Enter a percentile. The preset is 50.
    3. Select an operator.
    4. Enter a value.
    5. Select a duration time.
    For Metric:
    1. Select an mPulse built-in metric, such as Bounce Rate, or a custom metric.
    2. Select an operator.
    3. Depending on the metric selected, enter a count or whole number.
    4. Select a duration time.
  5. Select a time window to track when an event breaches the threshold, for example 10 minutes. This time can be as short as 5 minutes and as long as 24 hours. The preset is 5 minutes. If a threshold breach happens, an alert triggers and mPulse sends out the notification.
    Consider adding a buffer to prevent transient, undiagnosable events from triggering an alert.
    Note: Using a shorter time means fewer data points to calculate the percentile. A longer time lengthens the time between the event and the notification.
  6. Tell mPulse to keep watching the event up to 10 minutes before sending out the notification. Select the and persisted for checkbox, then select a time.
    mPulse evaluates a rolling window and recalculates each minute, for example, 5 minutes. If the event continues to breach the threshold, mPulse sends the alert notification.
  7. If you’d like to refine the condition, add a dimension:
    1. Under When, click the plus sign.
    2. In the menu, select an mPulse built-in dimension or a custom dimension.
    3. Select the dimension types, then click OK.
  8. Set up time windows.
