'Summary Period' Voicemail System Link Statistics

The following statistics are collected for a Voicemail System Link.


Parameter

Type of statistic

Description
Count of call history messages Count Number of Call History messages sent to the voicemail system (each message contains information about a call being passed to the voicemail system). This count corresponds to requirement R4-23 in GR-283-CORE issue 2.
Count of call history bytes Count Total number of bytes sent in Call History messages. This count corresponds to requirement R4-23 in GR-283-CORE issue 2.
Count of discarded call history bytes Count Number of bytes in Call History messages that were discarded because they could not be sent within the required timeout period. This count corresponds to requirement R4-24 in GR-283-CORE issue 2.
Count of SMDI Block messages Count Number of SMDI Block (BLK) messages transmitted to the voicemail system. A Block message is sent to indicate that a request from the voicemail system, to activate or deactivate the message waiting indicator for a subscriber, has been discarded because of a short term failure. This count corresponds to requirement R4-25 in GR-283-CORE issue 2.
Count of SMDI Block bytes Count Total number of bytes sent in SMDI Block messages. This count corresponds to requirement R4-25 in GR-283-CORE issue 2.
Count of SMDI Invalid messages Count Number of SMDI Invalid (INV) messages transmitted to the voicemail system. An Invalid message is sent to indicate that a request from the voicemail system, to activate or deactivate the message waiting indicator for a subscriber, has been discarded because of a short term failure. This count corresponds to requirement R4-25 in GR-283-CORE issue 2.
Count of SMDI Invalid bytes Count Total number of bytes sent in SMDI Invalid messages. This count corresponds to requirement R4-25 in GR-283-CORE issue 2.
Count of SMDI Operate messages Count Number of SMDI Operate (OP) messages received from the voicemail system. An Operate message is sent to indicate that the message waiting indicator should be activated for a particular subscriber. This count corresponds to optional requirement O4-35 in GR-283-CORE issue 2.
Count of SMDI Remove messages Count Number of SMDI Remove (RMV) messages received from the voicemail system. A Remove message is sent to indicate that the message waiting indicator should be deactivated for a particular subscriber. This count corresponds to optional requirement O4-35 in GR-283-CORE issue 2
Count of total SMDI Operate and Remove messages Count Total number of SMDI Operate and Remove messages received from the voicemail system. This count corresponds to requirement R4-26 in GR-283-CORE issue 2.
Count of total SMDI Operate and Remove bytes Count Total number of bytes received in SMDI Operate and Remove messages. This count corresponds to requirement R4-26 in GR-283-CORE issue 2.
Count of invalid messages Count The number of received SMDI messages that were not valid. This includes only messages that were correctly formatted, but did not contain valid information. It does not include bytes that could not be translated into valid SMDI messages. This count corresponds to requirement R4-28 in GR-283-CORE issue 2.
Proportion of asynchronous writes Percentage The percentage of writes to the SMDI link that could not complete synchronously. This indicates the percentage of messages that MetaSwitch could not send immediately because the link was busy and the outgoing buffer was full. This replaces the outgoing message buffer traffic measurements, R-29 and R-30, in GR-283-CORE issue 2.
Proportion of asynchronous reads Percentage The percentage of reads from the SMDI link that could not complete synchronously. This indicates the percentage of messages that MetaSwitch received from the voicemail system but could not process immediately. This replaces the incoming message buffer traffic measurements, R-29 and R-30, in GR-283-CORE issue 2.
