Host Template: Cloud - Azure - Container Service Managed Clusters

Overview Copied

Azure Container Service Managed Clusters allow you to quickly deploy production ready Kubernetes, DC/OS and Docker Swarm clusters. Azure Container Service manages hosted environments, making it quick and easy to deploy and manage containerised applications. It also eliminates the difficulty of ongoing operations and maintenance by provisioning, upgrading and scaling resources on demand without taking applications offline.

This Host Template allows you to monitor all the metrics you need to efficiently run Azure Container Service Managed Clusters on Microsoft Azure. After installation, you’ll be able to check the number of pods in the Ready state, the status of nodes, as well as the allocatable memory and CPU cores in the managed cluster.

This Host Template includes the following Service Checks:

Service Check Name Description Default Thresholds (Metric: Warning, Critical) UOM
Azure - Kube - Pods Ready

Number of pods in Ready state

[Default Timespan = 5mins, Default Check Interval = 5mins]

N/A N/A
Azure - Kube Node - Allocatable CPU Cores

Total number of available cpu cores in a managed cluster

[Default Timespan = 5mins, Default Check Interval = 5mins]

N/A N/A
Azure - Kube Node - Allocatable Memory

Total amount of available memory in a managed cluster

[Default Timespan = 5mins, Default Check Interval = 5mins]

N/A B
Azure - Kube Node - Status Condition

Statuses for various node conditions

[Default Timespan = 5mins, Default Check Interval = 5mins]

N/A N/A

Note

The “Default Timespan” given for these Service Checks refers to the time period we use when retrieving metrics from Azure.

Usage Instructions Copied

Please review the overall Cloud - Azure Opspack documentation for details on prerequisites, known issues, and other necessary configurations that apply to all Host Templates in the Opspack.

Add this Host Template Copied

Add the Cloud - Azure - Container Service Managed Clusters Host Template to your Opsview Monitor host. If the resource you’re monitoring has no hostname or public IP, then open the Advanced settings pane and change Host Check Command to Always assumed to be UP.

Note

For more information, refer to the documentation on Adding Host Templates to Hosts.

Add and configure Variables Copied

The Service Checks in this Host Template use the following variables, and they will be added to your Opsview Monitor instance alongside the Host Template:

Additional Information Copied

Please note, it can take a long time for all the associated metrics to be made available via Azure. This means that these Service Checks may not return results if the Cluster resource was created recently. For some of the Cluster Metrics you may have to wait over 6 hours after creation.
