I’m stuck with grpc limit and pulling data from zabbix data source via grafana. I couldn’t increase grpc memory.

I added these amounts but it didn’t work.

grpc_server_max_recv_msg_size
grpc_server_max_send_msg_size

error message: evel=error msg=“Internal server error” error=“[plugin.downstreamError] client: failed to call resources: failed to receive call resource response: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (19075682 vs. 16777216)”
