The Instances page lets you monitor instances (nodes) in the system. You can use the Admin App, CLI, and REST API to view a list of all instances in the system.
Viewing all instances
To view all instances, in the Admin App, click Dashboard > Instances.
The page shows all instances in the system. Each instance is identified by its IP address.
This table describes the information shown for each instance.
|Services||The number of services running on the instance.|
The total number of service units for all services and job types running on the instance, out of the best-practice service unit limit for the instance.
An instance with a higher number of service units is likely to be more heavily used by the system than an instance with a lower number of service units.
The Instances page displays a blue bar for instances running less than the best-practice service unit limit.
The Instances page displays a red bar for instances running more than the best-practice service unit limit.
|Load Average||The load averages for the instance for the past one, five, and ten minutes.|
|CPU||The sum of the percentage utilization for each CPU core in the instance.|
This section shows both:
|Memory Total||The total amount of RAM for the instance.|
|Disk Used||The current amount of disk space that your system is using in the partition on which it is installed.|
|Disk Free||The amount of free disk space in the partition in which your system is installed.|
Viewing the services running on an instance
To view the services running on an individual instance, in the Admin App:
Click Dashboard > Instances.
Select the instance you want.
The page lists all services running on the instance.
For each service, the page shows:
- The service name
- The service state:
- Healthy: The service is running normally.
- Unconfigured: The service has yet to be configured and deployed.
- Deploying: The system is currently starting or restarting the service. This can happen when:
- You move the service to run on a completely different set of instances.
- You repair a service.
- Balancing: The service is running normally, but performing background maintenance.
- Under-protected: In a multi-instance system, one or more of the instances on which a service is configured to run are offline.
- Failed: The service is not running or the system cannot communicate with the service.
- CPU Usage: The current percentage CPU usage for the service across all instances on which it's running.
- Memory: The current RAM usage for the service across all instances on which it's running.
- Disk Used: The current total amount of disk space that the service is using across all instances on which it's running.
