To monitor the subscriber in the SMF, use the following CLI command:

monitor subscriber [ capture-duration duration  | gr-instance gr_instance_id  | imei imei_id | imsi imsi_value | internal-messages [ yes ] | namespace [ sgw | smf ] | nf-service [ sgw | smf ] | supi supi_id | transaction-logs [ yes ] ] 

NOTES:

• capture-duration duration : Specify the duration in seconds during which monitor subscriber is enabled. The default value is 300 seconds (5 minutes). This is an optional parameter.

• gr-instance gr_instance_id : Specify the GR instance ID. The instance ID 1 denotes the local instance ID.

• imei imei_id : Specify the subscriber IMEI. For example: 123456789012345, *

• imsi imsi_value : Specify the subscriber IMSI. For example: 123456789, *

• internal-messages [ yes ] : Enable internal messages when set to yes . By default, it is disabled. This is an optional parameter.

• namespace [ sgw | smf ] : Enable the specified namespace. By default, namespace is set to none. This is an optional parameter.

  Important

  This keyword is deprecated in release 2021.02.0 and replaced with nf-service keyword.

• nf-service [ sgw | smf ] : Enable the specified NF service. By default, nf-service is set to none. This is an optional parameter.

  Important

  The nf-service keyword replaces the namespace keyword in release 2021.02 and beyond.

• supi supi_id : Specify the subscriber identifier. For example: imsi-123456789, imsi-123*

• transaction-logs [ yes ] : Enable transaction logs when set to yes . By default, it is disabled. This is an optional parameter.

  To view the transaction history logs, use the dump transactionhistory command.

  Note	The most recent transaction logs are stored in a circular queue of size 1024 transaction logs.

The monitor subscriber CLI command can be run simultaneously on multiple terminals. For example, run the CLI simultaneously in two SMF Ops Center terminals for two subscribers (for example, imsi-123456789012345 and imsi-456780123456789) to implement the following:

• Monitor the duration when the monitor subscriber is enabled

• View internal messages for the specified subscriber

• View transaction logs for the specified subscriber

Terminal 1: The following command monitors and displays subscriber messages for the specified subscriber.

monitor subscriber supi imsi-123456789012345 capture-duration 1000 internal-messages yes

Terminal 2: The following command monitors and displays transaction logs for the specified subscriber.

monitor subscriber supi imsi-456780123456789 capture-duration 500 internal-messages yes transaction-logs yes

After the capture duration is completed, stop the CLI by using the Ctrl+C keys. The captured messages are reordered and stored in a file. To retrieve the list of stored files, use the monitor subscriber list CLI command.

For example:

monitor subscriber list
RELEASE_NAMESPACE: 'smf'
'monsublogs/subscriberID_imsi-*_AT_2019-10-22T09:19:05.586237087.txt.sorted'
monsublogs/subscriberID_imsi-123456789012345_AT_2019-10-22T09:20:11.122225534.txt.sorted

To view the sorted file on the SMF Ops Center screen, use the following CLI command:

monitor subscriber dump filename filename 

For example:

monitor subscriber dump filename monsublogs/subscriberID_imsi-123456789012345_AT_2019-10-22T09:20:11.122225534.txt.sorted

To monitor the interface protocol on the SMF, use the following CLI command:

monitor protocol { interface interface_name [ capture-duration duration  | gr-instancegr_instance | pcacp yes | | ] | list [ | ] }  

NOTES:

• interface interface_name —Specify the interface name on which PCAP is captured. This CLI allows the configuration of multiple interface names in a single CLI command.

• capture-duration duration —Specify the duration in seconds during which pcap is captured. The default is 300 seconds (5 minutes).

• The configured interface names can be retrieved using the show endpoint CLI command.

• gr-instance gr_instance_id —Specify the GR instance ID. The instance ID 1 denotes the local instance ID.

• pcap yes —Configure this option to enable PCAP file generation. By default, this option is disabled.

Important

The monitor protocol command in Exec mode is restricted based on pod's CPU utilization configured through monitor protocol cpu-limit threshold_percentage command in the Global Configuration mode.

The monitor protocol CLI can be run simultaneously on multiple terminals. Also, the interface interface_name CLI allows the configuration of multiple endpoint names in a single CLI command.

For example:

monitor protocol interface sbi,N4:209.165.200.241:8805,gtpc capture-duration 1000 

Use the following configuration to enable UPF Monitor Subscriber from SMF.

config 
    monitor nf subscriber  [ gpsi gpsi_value |imei imei_id|imsiimsi_value control { true | false }  data { true | false } target-nf { sgwu | upf } ] 
    end 

NOTES:

• monitor nf —Specify the NF that you want to monitor.

• gpsi gpsi_value —Specify the subscriber GPSI.

• imsi imsi_value —Specify the subscriber IMSI. For example: 123456789, *

• imei imei_id —Specify the subscriber IMEI. For example: 123456789012345, *

• control { true | false } —Specify whether to enable or disable the control event tracing.

• data { true | false } —Specify whether to enable or disable the data event tracing.

• target-nf { sgwu | upf } —Specify the target NF as SGW-U or UPF. target-nf is an optional parameter and if an operator doesn't configure this parameter, monitor subscriber is enabled on both the UPF and SGW-U.

Configuration Example

The following is an example configuration.

[smf] smf(config)# monitor nf subscriber
   imsi 234150999999999
      control true
      data true 
      target-nf upf 
exit

Use the following configuration to disable UPF Monitor Subscriber from SMF.

config 
    [ no ]monitor nf subscriber  [ gpsi gpsi_value |imei imei_id | imsiimsi_value ] 
    end 

NOTES:

• monitor nf —Specify the NF that you want to monitor.

• gpsi gpsi_value —Specify the subscriber GPSI.

• imsi imsi_value —Specify the subscriber IMSI. For example: 123456789, *

• imei imei_id —Specify the subscriber IMEI. For example: 123456789012345, *

Files that are generated using the monitor subscriber command, monitor protocol command, and transaction logs are stored in the OAM pod. The files that are generated in OAM pod are collected and stored in an internal Apache server. You can view and download the files by using a web browser, after user authentication.

Note	Use the same credentials as ops-center to authenticate user access to the files present in the oam-pod and edr-monitor pod using a browser.

The files are created in separate folders, as and when their respective commands are executed. You can download the following OAM and EDR pod files:

• Monitor subscriber files: These files are generated using the monitor subscriber CLI option to trace messages that are related to a specified subscriber. The files that are generated for the monitor protocol command are present in the monsublogs/ directory.

• Monitor protocol files: These files are using the monitor protocol CLI option to capture packets on a specific interface provided under the CLI command. The files that are generated for the monitor protocol command are present in monprologs/ directory.

• Transaction logs: When transaction logging is enabled, the transaction logs are sent to oam-pod and can be downloaded from there. The files generated for transaction logging when enabled and are present in the transactionlogs/ directory.

• EDR files: These files are generated in smf service pod and periodically copied to edr-monitor pod. The files are available in /edr directory.
