Exchange ActiveSync Servers Test
Where Exchange ActiveSync is used to synchronize mobile devices with Exchange server mailboxes, Exchange administrators may want to know which devices are connecting to the server at any given point in time, so that accesses by unauthorized devices can be instantly detected and blocked. Administrators may also want to track the usage of mailboxes by mobile devices over time and identify the most and the least effective users, so that access policies can be accordingly drawn. Moreover, when a device user complains of a slowdown when accessing his/her mailbox, administrators may want to take a look at the network traffic generated by every device that is connecting to the server at the time of the slowdown, so that devices that are choking the bandwidth and causing the slowness can be accurately isolated. The Exchange ActiveSync Servers test performs all these checks periodically and provides Exchange administrators with actionable information that will enable them to take well-informed and intelligent performance/policy decisions.
This test auto-discovers the devices that are synchronizing with the Exchange mailboxes via ActiveSync, and for each device, reports the number of hits/accesses made by that device and the amount of data transmitted and received by that device. In the process, the test points administrators to the following:
- Devices that are currently connected to the Exchange server; unauthorized devices can thus be quickly captured;
- Devices that are accessing the Exchange server mailboxes frequently and those that seldom use the mailboxes; sizing and policy decisions can be taken based on this observation
- Devices that are consuming excessive bandwidth resources and could hence be contributing to the sluggish quality of the network;
Target of the test : A Microsoft Exchange 2013/2016 server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for each device or IP address that is currently accessing the mailboxes on the Exchange server

Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Total hits: |
Indicates the current number of hits/accesses to the Exchange mailbox server from this device. |

Comparing the value of this measure across devices will help you to identify the device that is constantly accessing the Exchange mailbox server and that which is not using the server as frequently. Based on these usage metrics, administrators can define access policies. Also, this measure serves as a good indicator of the level of device activity on the Exchange server; based on this knowledge, administrators can right-size their Exchange infrastructure – i.e., decide on how much CPU, memory, bandwidth, and disk resources the Exchange server has to be allocated so that it can handle the ActiveSync load. |
Data sent: |
Indicates the amount of data this device is currently sending to the Exchange mail server. |

Compare the value of these measures across the devices to identify the device that is currently generating the maximum amount of network traffic when interacting with its mailbox on the Exchange server. In the event of a slowdown, this comparative analysis will point administrators to that device which is engaged in bandwidth-intensive conversations with the Exchange server, thus causing accesses to slow down. During normal operations on the other hand, administrators can analyze these measures over time to gauge the average network throughput of ActiveSync activities; this can help them decide whether/not more network resources need to be allocated to handle ActiveSync load efficiently. |
Data received: |
Indicates the amount of data currently received by this device from the Exchange mail server. |

Average unique devices: |
Indicates the number of unique devices currently accessing the ActiveSync server. |
