# Differences Between Hourly and 24-Hour Event Logs

You receive event log files approximately every hour in addition to 24-hour log files. Review the differences between the two logs so that you can filter your files to analyze the event data you want.

|Hourly Log Files|24-Hour Log Files|
|----------------|-----------------|
|One or more files generated for every hour of activity.|One file generated for every 24 hours of activity.|
|Available in the API. You can manually import data into third-party visualization apps.|Available in the API and integrated with the Event Monitoring Analytics app and third-party visualization apps.|
|Key values in the EventLogFile object for hourly logs. See also these [Considerations](https://developer.salesforce.com/docs/platform/api-rest/guide/event-log-file-hourly-overview.md#query-or-view-hourly-event-log-files) regarding hourly event logs.|Key values in the EventLogFile object for 24-hour logs.|
|When an hourly incremental log file is delivered, a file with new logs for that hour is created. The `Sequence` field is incremented for each new file.|When a daily incremental log file is delivered, a new file replaces the original file with the full set of available logs for that date. The `CreatedDate` field is updated.|

Key values in the EventLogFile object for hourly logs:

-   `Interval`—Hourly
-   `CreatedDate`—Timestamp of when the log file was created. Use this field to identify new files.
-   `LogDate`—Timestamp that marks the beginning of the interval when the events occurred. For example, for events that occurred between 11:00 AM and 12:00 PM on 3/7/2016, this field’s value is 2016-03-07T11:00:00.000Z.
-   `Sequence`—1+. This value increases by 1 when events are added in the same hour after the latest event log file is created. The value resets to 1 in the subsequent hour.

Key values in the EventLogFile object for 24-hour logs:

-   `Interval`—Daily
-   `CreatedDate`—Timestamp of when the log file was created. Use this field to identify new files.
-   `LogDate`—Timestamp that marks the beginning of the interval when the events occurred. For example, for events that occurred on 3/7/2016, this field’s value is 2016-03-07T00:00:00.000+0000.
-   `Sequence`—0

**note:** Like with 24-hour event monitoring, hourly event log data is available for the past 30 days.
