Measures reported by BBerryAgtMsgTest
A good indicator of the health of the messaging agent is its ability to process and deliver all messages it receives to user handhelds promptly. If too many messages remain undelivered, then, you may want to investigate the reasons for the same and plug the holes quickly, so that the messages are delivered to the device without delay. With the help of this test, you can not only determine the message load on the messaging agent at any given point in time, but can also assess how well the messaging agent handles this load.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Failed_msg_count |
Indicates the total number of messages that the Messaging Agent failed to process during the last measurement period.
|
Number |
A low value is desired for this measure. A high value or a value that increases steadily indicates that the messaging agent is experiencing processing bottlenecks. Further investigation is hence recommended. |
| Pending_msg_count |
Indicates the total number of messages that have been recognized for delivery to the BlackBerry handheld devices from the Messaging Agent.
|
Number |
When the BlackBerry Enterprise Server is unable to deliver a message to the handheld device, the pending count on the BlackBerry Enterprise Server for that BlackBerry device user will increase by one.
Messages cannot be delivered to the BlackBerry device if it is outside an area of wireless network coverage or is turned off. Once the BlackBerry handheld device is turned on by the user, or returns to an area with wireless network coverage, the pending messages will be delivered. The pending count on the server will then decrease on the BlackBerry Enterprise Server. |
| Expired_msg_count |
Indicates the number of messages that were not delivered to the BlackBerry handheld device and are subsequently purged by the Blackberry Enterprise Server during the last measurement period.
|
Number |
Ten minutes after the connection between the BlackBerry® Enterprise Server and the BlackBerry® Infrastructure closes, the BlackBerry Infrastructure notifies the sender’s BlackBerry device and deletes the message that is not delivered.
The wireless network can queue up to 5 undelivered messages for up to 7 days. If more than 5 undelivered messages exist in the queue, the BlackBerry Enterprise Server stores the messages in the BlackBerry Configuration Database.
The BlackBerry Infrastructure does not store data to send to BlackBerry devices.
If the BlackBerry Infrastructure is not responding and the connection closes unexpectedly, the wireless network deletes the undelivered messages. The BlackBerry device does not receive the messages and it does not send acknowledgment packets to the BlackBerry Enterprise Server. When the BlackBerry Infrastructure becomes available again, the BlackBerry Enterprise Server resends messages that it did not receive acknowledgment packets for.
