i m with srsran release
git checkout 11c9bba

i have activated the kpi with following configuration in config file
metrics:
enable_json: true
remote_control:
bind_addr: 127.0.0.1
port: 55555
enabled: true

metrics:
layers:
enable_app_usage: true # Enable application usage metrics
enable_ngap: true # Enable NGAP metrics
enable_rrc: true # Enable CU-CP RRC metrics
enable_e1ap: true # Enable E1AP metrics
enable_pdcp: true # Enable PDCP metrics
enable_cu_up_executor: true # Whether to log CU-UP executor metrics
enable_sched: true # Enable DU scheduler metrics
enable_rlc: true # Enable RLC metrics
enable_mac: true # Enable MAC metrics
enable_executor: true # Whether to log DU-high executor metric s
enable_du_low: true # Enable DU low metrics (upper physical layer)
enable_ru: true # Enable Radio Unit metrics
periodicity:
app_usage_report_period: 1000 # Application resource usage metrics report period (in milliseconds)
cu_cp_report_period: 1000 # CU-CP metrics report period in milli seconds
cu_up_report_period: 1000 # CU-UP metrics report period in millis econds
du_report_period: 1000 # DU statistics report period in mill iseconds

i get the following output

in the past i was use ti have metrics about signal rsrp rsrq sinr ....what should i activate to get such metrics with this release ? is there documentation regarding kpi handled in srsran ?
