Stackdriver Monitoring is a service of GCP, which tracks the performance of instances and services running on them. Using this service, we can monitor the servers health and hence that of the applications running on them. The service also enables us to create custom metrics and visualize them on dashboards.
To play with the features of Stackdriver Monitoring, we'll setup a new Stackdriver account, install Stackdriver agents on an instance, monitor the instance, create alerting policies, and create metrics dashboard.
