    Event types supported by this network can by retrieved by using the Get-MerakiNetworkEventTypes function.

    Get content filtering network events for a network.

    .EXAMPLE
    Get network events for a specific client
    PS> Get-MerakiNetworkEvents -clientName 'DALJohnDoe'
    .EXAMPLE
    Paging:
    The maximum number of events you can retrieve per call is 1000. There are many events and 1000 events may only span a time period of a few minutes.
    To retrieve more events you can use subsequent function calls with the paging parameters.
    In the following command we retrieve the the content filtering events for the Dallas network for the month of June.
    PS> Get-MerakiNetworks |{$_.Name -like "Dallas"} | Get-MerakiNetworkEvents -includedEventTypes 'cf_block' -ProductType appliance -startingAfter "06/01/2020" -endingBefore "06/30/2020" -pageSize 50
    .EXAMPLE
    This call will retrieve the first 50 events that meet the time span specified.
    There are significantly more events that meet this criteria.
    To retrieve the next page of events reissue the call and append the -next paging parameter.
    PS>Get-MerakiNetworks |{$_.Name -like "Dallas"} | Get-MerakiNetworkEvents -includedEventTypes 'cf_block' -ProductType appliance -startingAfter "06/01/2020" -endingBefore "06/30/2020" -pageSize 50 -next
