Monitor Dedicated Gen 3 metrics
Back to home
On this page
Dedicated Gen 3 environments consist of various containers running across dedicated hosts:
- App containers: one or more app containers
- Service containers: zero or more service containers
- Worker containers: zero or more worker instances.
Infrastructure metrics report CPU, RAM, and disk space for all containers.
By default, the graphs include all hosts and an average over the hosts. To select metrics for specific hosts, click Filter.
The ID numbers for the hosts in the list for filtering match the numbers for interacting with a host, such as for accessing the environment using SSH.
Example of how to read metrics 
This example should give you an idea of how the metrics appear. Dedicated Gen 3 environments metrics show resource usage for each app, service, and worker container across all hosts.
This reference project has a single app, two services (MySQL and Redis), and one worker.
Once you’ve read the metrics, see recommendations for action.
App container
Metrics graphs for the app container show CPU, RAM, and disk allocation and usage across all hosts. The persistent disk has been configured in the app configuration at 4.86 GB, while the temporary disk is 3.99 GB by default.
Service containers
Metrics graphs for the service containers show CPU, RAM, and disk allocation and usage across all hosts.
MySQL
Metrics graphs for the MySQL service container show CPU, RAM, and disk allocation and usage across all hosts. The persistent disk has been configured in the services configuration as 24.55 GB, while the temporary disk is 3.99 GB by default.
Redis
Metrics graphs for the Redis service container show CPU, RAM, and disk allocation and usage across all hosts. No persistent disk has been configured for Redis, while the temporary disk is 3.99 GB by default.
Worker container
Metrics graphs for the Scheduler worker container show CPU, RAM, and disk allocation and usage across all hosts. The persistent disk has been configured in the app configuration at 4.86 GB (the same as the app), while the temporary disk is 3.99 GB by default.
