BlackBerry Messaging Test

This test reveals how effectively BES handles mails sent to and received from handheld devices.

Target of the test : A BlackBerry Enterprise Server

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for each server being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed

Host

The IP address of the host for which this test is to be configured.

SNMPPort

The port at which the monitored target exposes its SNMP MIB; The default value is 161.

SNMPVersion

By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the SNMPversion list is v1. However, if a different SNMP framework is in use in your environment, say SNMP v2 or v3, then select the corresponding option from this list.

SNMPCommunity

The SNMP community name that the test uses to communicate with the firewall. This parameter is specific to SNMP v1 and v2 only. Therefore, if the SNMPVersion chosen is v3, then this parameter will not appear.

Username

This parameter appears only when v3 is selected as the SNMPversion. SNMP version 3 (SNMPv3) is an extensible SNMP Framework which supplements the SNMPv2 Framework, by additionally supporting message security, access control, and remote SNMP configuration capabilities. To extract performance statistics from the MIB using the highly secure SNMP v3 protocol, the eG agent has to be configured with the required access privileges – in other words, the eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB. Therefore, specify the name of such a user against this parameter. 

Context

This parameter appears only when v3 is selected as the SNMPVersion. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the SNMPEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName). If the Username provided is associated with a context name, then the eG agent will be able to poll the MIB and collect metrics only if it is configured with the context name as well. In such cases therefore, specify the context name of the Username in the Context text box.  By default, this parameter is set to none.

AuthPass

Specify the password that corresponds to the above-mentioned Username. This parameter once again appears only if the SNMPversion selected is v3.

Confirm Password

Confirm the AuthPass by retyping it here.

AuthType

This parameter too appears only if v3 is selected as the SNMPversion. From the AuthType list box, choose the authentication algorithm using which SNMP v3 converts the specified username and password into a 32-bit format to ensure security of SNMP transactions. You can choose between the following options:

  • MD5 - Message Digest Algorithm
  • SHA - Secure Hash Algorithm
  • SHA224 - Secure Hash Algorithm 224 bit
  • SHA256 - Secure Hash Algorithm 256 bit
  • SHA384 - Secure Hash Algorithm 384 bit
  • SHA512 - Secure Hash Algorithm 512 bit

EncryptFlag

This flag appears only when v3 is selected as the SNMPversion. By default, the eG agent does not encrypt SNMP requests. Accordingly, the this flag is set to No by default. To ensure that SNMP requests sent by the eG agent are encrypted, select the Yes option. 

EncryptType

If the EncryptFlag is set to Yes, then you will have to mention the encryption type by selecting an option from the EncryptType list. SNMP v3 supports the following encryption types:

  • DES - Data Encryption Standard
  • 3DES - Triple Data Encryption Standard
  • AES - Advanced Encryption Standard
  • AES128 - Advanced Encryption Standard 128 bit
  • AES192 - Advanced Encryption Standard 192 bit
  • AES256 - Advanced Encryption Standard 256 bit

EncryptPassword

Specify the encryption password here.

Confirm Password

Confirm the encryption password by retyping it here.

Timeout

Specify the duration (in seconds) within which the SNMP query executed by this test should time out in this text box. The default is 10 seconds.

Data Over TCP

By default, in an IT environment, all data transmission occurs over UDP. Some environments however, may be specifically configured to offload a fraction of the data traffic – for instance, certain types of data traffic or traffic pertaining to specific components – to other protocols like TCP, so as to prevent UDP overloads. In such environments, you can instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP). For this, set this flag to Yes. By default, this flag is set to No.

EngineID

This parameter appears only when v3 is selected as the SNMPVersion. Sometimes, the test may not report metrics when AES192 or AES256 is chosen as the Encryption type. To ensure that the test report metrics consistently, administrators need to set this flag to Yes. By default, this parameter is set to No.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Many Messages processed

Indicates the number of messages processed by the BES during the last measurement period.

Number

This value includes messages to handheld devices, from handheld devices, and filtered messages.

Many Messages sent to handheld

Indicates the current number of messages that passed the filter criteria and were sent to handheld devices.

Number

This value does not include calendar items.

Few Messages sent from handheld

Indicates the number of messages currently sent from handhelds during the last measurement period.

Number

This value does not include calendar items.

Few Messages pending delivery

Indicates the number of messages that are currently awaiting delivery to the handhelds.

 

Number

If the value of this measure is high or is increasing steadily, it could be a cause for concern, as it indicates a bottleneck in message delivery. This, in turn, could cause an increase in the size of the incoming message queue.

Few Messages expired

Indicates the total number of messages that timed out without being forwarded to the handheld during the last measurement period.

Number

Typically, messages time out after 7 days of non-delivery to the handheld. Messages can also time out if a user is not in a wireless network coverage area.

 

Few Undeliverable messages

Indicates the current number of messages that could not be delivered due to errors.

Number

Ideally, the value of this measure should be low. A high value for this measure would require an investigation. 

Few Messages filtered

Indicates the number of messages to which the BlackBerry Enterprise Server applied filters and therefore did not forward to handhelds during the last measurement period.

Number

You can create email message filters to define which messages the BlackBerry Enterprise Server forwards from email applications to BlackBerry devices. When users receive messages in the incoming message queue, the BlackBerry Enterprise Server applies email message filters to determine how to direct the messages: forward, forward with priority, or do not forward to the BlackBerry devices. If messages were not forwarded to handhelds because of a ‘do not forward’ filter, then such messages will be included in this count.
