Event Time Constraints

Each event has a time stamp that indicates when the event occurred. You can constrain the information that appears in some workflows by setting the time window, sometimes called the time range.

Workflows based on events that can be constrained by time include a time range line at the top of the page.

By default, workflows use an expanding time window set to the past hour. For example, if you log in at 11:30 AM, you will see events that occurred between 10:30 AM and 11:30 AM. As time moves forward, the time window expands. At 12:30 PM, you will see events that occurred between 10:30 AM and 12:30 PM.

You can change this behavior by setting your own default time window in the event view settings. This governs three properties:

  • time window type (static, expanding, or sliding)

  • time window length

  • the number of time windows (either multiple time windows or a single global time window)

Regardless of the default time window setting, you can manually change the time window during your event analysis by clicking the time range at the top of the page, which displays the Date/Time pop-up window. Depending on the number of time windows you configured and the type of appliance you are using, you can also use the Date/Time window to change the default time window for the type of event you are viewing.

Finally, you can pause the time window while looking at a sliding or expanding workflow. See Pause the Time Window to Temporarily Freeze the Data Set.
