Medium I am currently following the documentation from https://docs.o-ran-sc.org/projects/o-ran-sc-ric-plt-ric-dep/en/latest/installation-guides.html#installing-near-realtime-ric-in-ric-cluster.
I am currently using the KPIMON xApp to test everything.
That's where the problems start... The app doesn't seem to register properly:
{"ts":1705503041178,"crit":"DEBUG","id":"kpimon","mdc":{"CONTAINER_NAME":"","HOST_NAME":"","PID":"7","POD_NAME":"","SERVICE_NAME":"","SYSTEM_NAME":"","time":"2024-01-17T14:50:41"},"msg":"Application='kpimon-go' is not ready yet, waiting ..."}
{"ts":1705503042160,"crit":"DEBUG","id":"kpimon","mdc":{"CONTAINER_NAME":"","HOST_NAME":"","PID":"7","POD_NAME":"","SERVICE_NAME":"","SYSTEM_NAME":"","time":"2024-01-17T14:50:42"},"msg":"App registration is not done yet, sleep 5s and check again"}
I then tried to register the xApp manually:
curl -X 'POST' 'http://10.110.43.166:8080/ric/v1/register' -H 'accept: application/json' -H 'Content-Type: application/json' -d '{ "appName": "kpimon-go", "appVersion": "2.0.1", "appInstanceName": "kpimon-go", "httpEndpoint": "10.100.236.127:8080", "rmrEndpoint": "10.97.0.236:4560", "config": "" }'
Unfortunately, I don't know exactly how to validate whether this works successfully.
When I output the logs from appmgr, I only see the logs that are output directly after the start. Afterwards the logs are empty:
cp: cannot stat '/opt/ric/certificates/*': No such file or directory 2024/01/17 14:03:47 Using config file: /opt/ric/config/appmgr.yaml redis: got 7 elements in COMMAND reply, wanted 6 2024/01/17 14:03:47 Serving app manager at http://[::]:8080
What am I missing?
UPDATE:
Now with the help of tchyang I got a step further.
Unfortunately I still have problems..
It seems that the rmrSendToE2T fails during a new CRESTSubscriptionRequest.
Here is the logging I get when trying to get the KPIMON-GO xApp up and running.
submgr:
