    Overview

    This page explains how to configure failover and module-based failover. Learn how to set access modes (Active-Passive or Active-Active) and ensure redundancy for critical server roles to maintain continuous log management and high availability.

    Configuring failover

    1. Log in to your account.
    2. Go to the Settings tab.
    3. Under Admin Settings, navigate to Enterprise Essentials and select Failover.

    4. Click Configure Log Processor to proceed. You will be redirected to the Log Processor configuration page.
    5. NOTE: If the Log Processor is already configured, you will be automatically redirected to the Failover Configuration page.

      NOTE: To enable failover, you must assign roles to two or more Log Processors. Refer to this help document to configure Log Processors.
    6. Once you have configured the Log Processors, return to the Failover configuration page.
    7. If the Failover Status displays Common Access Mode has not been configured, click Configure next to Access Mode.

    8. In the Access Mode Configuration window, choose one of the following deployment types:
      • Virtual IP/HostName (Active-Passive): Suitable when servers are on the same subnet.
      • Access Gateway Cluster (Active-Active): Select this mode if an Access Gateway Cluster has already been configured and will be used to route external requests.
    9. If you choose Active-Passive (Virtual IP/HostName):
      • In the Access Mode Configuration window, select Virtual IP/HostName.

      • Click Update to save the configuration.
    10. If you choose Active-Active (Access Gateway Cluster):
      • Select Access Gateway Cluster in the Access Mode Configuration window.

      • Follow the configuration steps to set up the Access Gateway Cluster.
        • NOTE: Refer to this help document for detailed instructions on configuring Access Gateway Cluster.
      • Once configured, return to the Access Mode Configuration screen and click Update to apply the settings.

    Configuring module-based failover

    Follow the steps below to configure failover for a specific component.

    1. Log in to your account.
    2. Go to the Settings tab.
    3. Under Admin Settings, navigate to Enterprise Essentials and select Failover.
    4. In the Failover page, locate the section for which you want Failover to be enabled.
    5. Click Configure next to the message Failover Server Not Configured.

    7. Ensure the toggle next to Archive Status is enabled.
      NOTE: Repeat this step for at least one additional processor to ensure failover is supported. To learn how to add additional Log Processors, refer to this help document.
