KPM metrics with slice id label

[mhmd97z]

Hello, how to get the KPM metrics for UEs with their slice id attached to them? Thanks!

Currently, not supported by the E2 agent in the srsRAN-5G gnb.
But if you connect an agent that supports it, and sends a RIC indication with labels, it should be possible to decode and display them.

Thanks for your response.
Would it be possible for you to give some hints on how to develop this on srsRAN-5g? Which components need to be changed?

hi @pgawlowicz, What types of metrics can kpm_mon_xapp measure? Thanks!

[pgawlowicz]

Depends on which metrics are supported by the E2 Agent. For example, you can check here the supported metrics by srsRAN:

Hi @pgawlowicz, base on this e2sm_rc_control_style_def, can I create a new ran control service for xapp in oran sc ric?
https://github.com/srsran/srsRAN_Project/blob/main/lib/e2/e2sm/e2sm_rc/e2sm_rc_control_service_impl.h#L43

inline bool get_e2sm_rc_control_style_def(uint32_t style_id, e2sm_rc_control_service_def_t& control_service_def)
{
  static const std::array<e2sm_rc_control_service_def_t, NOF_E2SM_RC_CTRL_SERVICE_STYLES> style_defs = {{
      {1, "Radio Bearer Control", 1, 1, 1, 1},
      {2, "Radio Resource Allocation Control", 1, 1, 1, 1},
      {3, "Connected Mode Mobility Control", 1, 1, 1, 1},
      {4, "Radio Access Control", 1, 1, 1, 1},
      {5, "Dual Connectivity (DC) Control", 1, 1, 1, 1},
      {6, "Carrier Aggregation (CA) Control", 1, 1, 1, 1},
      {7, "Idle Mode Mobility Control", 1, 1, 1, 1},
      {8, "UE Information And Assignment", 0, 1, 1, 1},
      {9, "Measurement Reporting Configuration Control", 0, 1, 1, 3},
      {10, "Beamforming Configuration Control", 0, 1, 1, 0},
      {255, "Multiple Actions Control", 1, 2, 2, 2},
  }};

Thanks!
