Monitoring
General Service monitoring
Every Azure Compute Instances can have basic service monitoring such as CPU, Memory and Disk utilization
Stackdriver can do in-guest and Service monitoring
VM Service monitoring
Every Azure instance sends basic metrics to Azure Monitor. More metrics and information can be gathered using OMS
The OSS monitoring service details metric data, including basic system operation statuses, performance, and metering. It also provides a custom alarm service to track requests, analyze usage, collect statistics on business trends, and promptly discover and diagnose system problems.
Every GCP instance sends basic metrics to Stackdriver. More metrics and one-minute monitoring are available at cost.
Actions / Event logging
Log Analytics with OMS or using Azure Monitor
The alarm rule page is where you can view, modify, activate, deactivate, and delete alarm rules related to OSS monitoring alarms.
Logging for GCP instances is possible with the service Stackdriver Logs
