GTP' Agent Configuration(4.3)
The configuration of the GTP' agent includes the following tabs:
- Source
- Miscellaneous
- Advanced
Source Tab
The Source  tab includes connection type settings.
Item | Description |
---|---|
Protocol | The protocol type that you want the agent to use: TCP or UDP. For further information, see Limitations - GTP' Transported Over TCP in GTP' Agent MZSH Commands, Events and Limitations(4.3). |
Port | The port through which the agent should await incoming data packages. This port must be located on the host where the EC is running. The default value is set to 3386. Note! Two workflows that are running on the same EC, can subscribe to the same Port and GSNs, if they use different Protocol settings. |
GSN IP Address | The IP addresses or hostnames of the GSN nodes that provide the data. |
Server Port | The server port number for each node. The agent will detect GGSN source port changes via the Node Alive Request or Echo Request messages. If a change is detected, it is is registered in the System Log. The agent's internal configuration is updated. |
Note!
If more than one source is defined on one IP address, port changes are not supported and only connections from the specified ports are accepted from that host.
Miscellaneous Tab
The Miscellaneous tab includes collected format and storage settings of the data that is collected by the agent.
Field/Option | Description |
---|---|
Format | Format must match the D |
Perform Format Version Check | When selected, the |
Format Version | Format version must match the D |
Directory | Specify either the relative pathname to the home directory of the user account, or the absolute pathname of the target directory in the file system on the local host, where the intermediate data for the collection is stored. The intermediate data includes:
|
Acknowledgement from APL | Select this checkbox to enable an acknowledgement from the APL module that connects to the GTP' agent. This enables you to make sure that data is transmitted completely. |
No Private Extension | Select this checkbox to remove the private extension from any of the agent's output messages. |
Use seq num of Cancel/Release req. | Select this checkbox to change the type of the sequence numbers that are populated in a |
Advanced Tab
The Advanced tab consists of the transmission, sequence and duplicate handling settings for the agent.
Item | Description |
---|---|
Max Wait for a Response (sec) | The maximum time for which the GTP' agent can expect a If both this value and the Max Number of Request Attempts value, are exceeded, a message is sent to the System Log. For example: If Max Wait for a Response is 20 and Max Number of Request Attempts is 5, the warning message will be logged after 100 seconds. Note! The value also indicates the maximal period during which the GTP' agent awaits a |
Max Number of Request Attempts | Specify the maximum number of attempts to perform in order to receive a |
Max Outstanding Numbers | Specify the maximal number of packages that you want kept in memory for sequence number checking. |
Max Drift Between Two Numbers | Specify the maximum numbers that can be skipped between two sequence numbers. |
Clear Checking | Select this checkbox to avoid saving the last sequence number when the workflow has been stopped. Clear the checkbox to save the sequence number of the last collected package when the workflow is stopped. This way, as soon as the workflow is restarted, a package with the subsequent number is expected and the workflow continues processing from the where it had stopped. |
Agent Handles Duplicates | Select this option to store duplicates in a persistent data directory that you specify on the Miscellaneous tab. The packet will remain in the directory until the agent receives a request to release or to cancel it. |
Route Duplicates to | Select this option to route duplicates to a link that you select from the drop-down list. |
Alternate Node | Enter the hostname or IP-address of a host that runs an alternate Charging Gateway device as a backup. If you enter an IP address, the GTP' agent will include it in the redirection request that it sends to the GSN. Note! The GTP' agent does not backup any of the data that it manages. Make sure that the GSN node takes care of backup. |
Decoder Tab
The Decoder tab consists of the decoder settings.
Item | Description |
---|---|
Decoder | Click Browse and select a pre-defined decoder. These decoders are defined in the Ultra Format Editor, and are named according to the following syntax:
The option MZ Format Tagged UDRs indicate that the expected UDRs are stored in the specific format. Select this option to make the Tagged UDR Type list accessible for configuration. |
Tagged UDR Type | Click Browse and select a pre-defined Tagged UDR Type. These UDR types are stored in the Ultra and Code servers. The naming format is:
If the decoder is intended to reprocess UDRs of an internal format, the Decoder MZ format tagged UDRs has to be selected enabling this list. Once enabled, the internal format must be selected. |
Full Decode | Select this check box to enable full decoding of the UDR, before it enters the workflow. This, in turn, might reduce performance rate. Clear this check box empty to minimize decoding work in the agent. By leaving this check-box empty, you postpone decoding, and discovery of corrupt data to a later phase in the workflow. |
