Google Kubernetes Engine Stackdriver logging/monitoring is gone at gke version 1.15

Question

I'm using GKE for more than year and i never had any problems with stackdriver logging/monitoring. But when i created new cluster with version 1.15.9-gke.26 i don't see any logs in stackdriver (neither metrics). It also didn't work with new cluster with version 1.14. Although it works for older cluster which was updated to version 1.14 from 1.13.

Some settings:
gke version = 1.15.9-gke.26
Stackdriver Kubernetes Engine Monitoring = System and workload logging and monitoring
VPC-native (alias IP) = Enabled
Workload Identity = Disabled

Weird things:
Following daemon sets have 0/0 pods (DaemonSet has no nodes selected):
- metadata-proxy-v0.1
- nvidia-gpu-device-plugin (doesn't sound useful)

I'm not sure how exactly stackdriver works and how to debug it... I will appreciate any tips

Deployments and daemonsets currently running at cluster:

Answer 1

per documentation, and as @Darshan Naik mentioned:

If you are using Legacy Logging and Monitoring, then you must switch to Kubernetes Engine Monitoring before support for Legacy Logging and Monitoring is removed. Legacy Logging and Monitoring will no longer be supported as of GKE 1.15.
