VMware Aria Operations uses collectors like cloud proxies or remote collectors to manage cloud account processes such as gathering metrics from objects. You can select a collector or a collector group when configuring an cloud account.
If there are remote collectors or cloud proxies in your environment, you can create a collector group, and add the remote collectors or cloud proxies to the group. When you assign an account to a collector group, that account can use any collector in the group. Use collector groups to achieve resiliency in cases where the collector experiences network interruption or becomes unavailable. If this occurs, and the collector is part of a group, the total workload is redistributed among all the collectors in the group, reducing the workload on each collector. For more information, see the 'About VMware Aria Operations Remote Collector Nodes' topic in the Getting Started with VMware Aria Operations Guide and 'Configuring Cloud Proxies in VMware Aria Operations' topic in the Configuring VMware Aria Operations Guide.
You can add, edit, or remove collector groups in VMware Aria Operations, and rebalance your cloud accounts.
Rebalancing a Cloud Account
Rebalancing of your cloud accounts is not intended to provide equally distributed cloud accounts across each collector in the collector group. The rebalancing action considers the number of resources that each cloud account collects to determine the rebalancing placement. The rebalancing happens at the cloud account, which can result in several small cloud accounts on a single collector, and a single huge cloud account on another collector, in your VMware Aria Operations instance.
Rebalancing your collector groups can add a significant load on the entire cluster. Moving cloud accounts from one collector to another collector requires that VMware Aria Operations stops the cloud account and all its resources on the source collector, then starts them on the target collector.
If a collector fails to respond or loses connectivity to the cluster, VMware Aria Operations starts automated rebalancing in the collector group. All other user-initiated manual operations on the collector, such as stopping or restarting the collector manually, do not result in automated rebalancing.
If one of the collectors fails to respond, or if it loses network connectivity, VMware Aria Operations performs automated rebalancing. In cases of automated rebalancing, to properly rebalance the collector group, you must have spare capacity on the collectors in the collector group.
Where You Manage Collector Groups
From the left menu, click Collector Groups tab.
, and then click theOptions | Description |
---|---|
Collector Group toolbar | To manage collector groups, use the toolbar icons.
|
Name | The name given to the collector group when the collector group is created or updated. |
Collector Group ID | The collector group ID created when the collector group is created. |
Description | Description given to the collector group when the collector group is created or updated. |
Application Monitoring HA | Displays the application monitoring high availability status of the collector group.
Note: For default collector groups, high availability for application monitoring is deactivated by default.
|
HA Status | Displays the application monitoring high availability of the collector group.
Note: If the high availability status of the cloud proxy fails, the HA status of the failed cloud proxy is displayed. In case there are multiple cloud proxies in a collector group with failed HA status, the first failed message is displayed in the Collectors Group page.
|
Virtual IP | Virtual IP address of the collector group.
Note: Pick the Virtual IP address that any of the cloud proxies in a collector group can own and receive traffic from. The Virtual IP address must be in the same subnet as the physical address of the cloud proxies. After you configure the Virtual IP address, ping it from a different network to ensure that it is routable.
