This topic covers some frequently asked questions about vRealize Operations Proxy.

Configuration

  1. What are the prerequisites for setting up a cloud proxy account?

    Prerequisites are given in the topic, Configuring Cloud Proxies in vRealize Operations.

  2. What does one-way connection mean?

    Only outbound connections are initiated from cloud proxy to vRealize Operations, over tcp/443. Inbound ports to cloud proxy are not required. This ensures higher security as firewall ports need not be open to allow incoming connections. Also, cloud proxy can facilitate vCenter actions.

  3. How do I edit environment settings for cloud proxy?

    You can edit vApp options. For more information, see Edit OVF Details for a Virtual Machine.

  4. How are certificates managed?

    Certificates are managed by cloud proxies. But for any additional proxy servers with SSL communication, you need to provide certificate(s).

  5. What credential is used to login to cloud proxy?

    You can login as the “root” user. You are expected to set a new password on the first login to cloud proxy VM.

    SSH access is disabled by default, so the first login must be done via the vCenter console. You can run the following command to start SSH service: 
    systemctl start sshd
systemctl enable sshd

    To reset password, see the VMWare KB Article, 2001476.

  6. Where can I configure the local HTTP proxy for VMC on AWS?

    Perform the following steps:

    1. Login to vRealize Operations and go to the Administration page.
    2. Go to Cloud Accounts.
    3. Select VMC on AWS.
    4. Click + next to credentials to add a credential.
    5. In proxy details, add details for the local HTTP proxy. (Do not add details for cloud proxy here).

    For more details, see the Configuring VMware Cloud on AWS in vRealize Operations Cloud topic in the vRealize Operations Configuration Guide.

  7. Will I be notified if the connection between cloud proxy and vRealize Operations breaks down?

    You can configure alerts/notifications on the vRealize Operations cloud proxy object. For more information, see Monitoring the Health of Cloud Proxies.

    vRealize Operations automatically generates notifications for the following scenarios:
    • Cloud proxy is not reachable.
    • Cloud proxy is nearing sizing limits.
  8. How do I change account for cloud proxy?

    You can edit vApp options. For more information, see Edit OVF Details for a Virtual Machine.

  9. How can I check the status of cloud proxy?

    For more information, see Monitoring the Health of Cloud Proxies.

Sizing

  1. How should I size the cloud proxy?

    For information on sizing, see the VMWare KB article 85832

  2. How would I know if cloud proxy is nearing sizing limit?

    vRealize Operations customers will receive an email when cloud proxy is nearing sizing limit.

Upgrade

  1. How do I upgrade cloud proxy?

    Cloud proxy is upgraded automatically. In case the upgrade fails, see the VMWare KB article 80590.

Migration

  1. What is the difference between Remote Collector, Application Remote Collector and cloud proxy?

    The Remote Collector performs the data collection role from remote location sites and uploads data to the analytics nodes. Bidirectional connectivity is required between Remote Collector and analytics nodes. The Application Remote Collector discovers and collects data for applications running in Guest operating systems at a scale .

    Cloud proxy takes the role for both Remote Collector and Application Remote Collector, in addition, it needs only one-way connectivity to analytics nodes and does not require connectivity from analytics nodes to itself.

    The best practice for the on-prem vRealize Operations users is to leverage cloud proxy, for the vRealize Operations Cloud users this is the only supported option.

  2. Should I use Remote Collector or cloud proxy for monitoring?

    VMWare recommends that you use cloud proxy to take advantage of the latest enhancements. Also, application monitoring is only supported through cloud proxy.

High Availability

  1. Is high availability supported?
    Cloud proxy supports high availability. You can add multiple cloud proxies to a collector group. If the collecting cloud proxy fails or gets disconnected, collection can be picked up by another proxy in the group.
    Note: Since the failover is initiated after a period of 10 minutes, few collection cycles are lost.
