Get-MailTrafficTopReport

The Action parameter filters the report by the action taken by DLP policies, transport rules, malware filtering or spam filtering. To view the complete list of valid values for this parameter, run the command Get-MailFilterListReport -SelectionTarget Actions. The action you specify must correspond to the report type. For example, you can only specify malware filter actions for malware reports.

You can specify multiple values separated by commas.

The AggregateBy parameter specifies the reporting period. Valid values are Hour, Day or Summary. The default value is Day.

The Direction parameter filters the results by incoming or outgoing messages. Valid values for this parameter are Inbound and Outbound.

The Domain parameter filters the results by an accepted domain in the cloud-based organization. You can specify multiple domain values separated by commas or the value All.

The EndDate parameter specifies the end date of the date range.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format mm/dd/yyyy, enter 09/01/2018 to specify September 1, 2018. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2018 5:00 PM".

The EventType parameter filters the report by the event type. To view the complete list of valid values for this parameter, run the command Get-MailFilterListReport -SelectionTarget EventTypes. The event type you specify must correspond to the report. For example, you can only specify malware filter events for malware reports.

The StartDate parameter specifies the start date of the date range.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format mm/dd/yyyy, enter 09/01/2018 to specify September 1, 2018. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2018 5:00 PM".

The SummarizeBy parameter returns totals based on the values you specify. If your report filters data using any of the values accepted by this parameter, you can use the SummarizeBy parameter to summarize the results based on those values. To decrease the number of rows returned in the report, consider using the SummarizeBy parameter. Summarizing reduces the amount of data that's retrieved for the report and delivers the report faster. For example, instead of seeing each instance of a specific value of EventType on an individual row in the report, you can use the SummarizeBy parameter to see the total number of instances of that value of EventType on one row in the report.

For the Get-MailTopTrafficReport cmdlet, the SummarizeBy parameter accepts the values Domain and EventType. You can specify multiple values separated by commas.
