I am collecting metrics from Monitoring in google cloud through rest-api. In the api documentation from https://cloud.google.com/monitoring/api/metrics_gcp I am seeing lot of metrics beginning with guest like
guest/cpu/usage_time
guest/disk/bytes_used
guest/disk/io_time
I am seeing the same kind of metrics beginnging with instance like
instance/cpu/usage_time
instance/disk/max_read_bytes_count
I have searched the documentation, but I am not getting clear idea of what is the difference between guest and instance metrics. Which metrics is preferred? Can anyone give suggestion? Thanks
The guest/... is used to monitor the system health of COS instances.
While for the instance/... it is targeted at regular GCE VM instances metrics not COS instance type.
