    Custom BIP for Project Nodes

    BIP (Bridge IP) is the IP address of docker0, the default bridge of Docker for a project. All containers that do not specify a network connect to this bridge, and subnet IP addresses are assigned through it.

    When deploying a new project or adding a node to an existing project, you can specify the node's Docker BIP to prevent deployment failures caused by occupied network segments.

    For details, see New Project Deployment.

    Custom Backup Storage Location

    Project backups are stored in the FineOps mounting directory by default. When local disk space is insufficient, you need to expand the physical disk or change the FineOps mounting directory to a location with more available space, which requires high operational effort.

    From this version, you can customize backup storage locations. You can write backups to your own S3 storage without preparing another mounting directory due to insufficient physical disk space.

    For details, see Project Backup.

    Relaxed Resource Validation for Adding and Scaling Components

    Resource validation for nodes is relaxed when components are added or scaled. Deployment is allowed when the available resources of a node reach 7/8 of the estimated required amount. For example, if a component is estimated to require 8 GB of memory, deployment is allowed when the available memory of the node is 7 GB.

    iconNote:
    The 7/8 rule does not remove the need for runtime monitoring. After deployment, keep monitoring node CPU, memory, and component status, and increase node resources if resource pressure persists.

    For details, see Adding Components to O&M Projects.

    Optimized System Checks for FineDataLink Projects

    The following check items have been optimized or applied for FineDataLink projects.

    Check Item
    Update Description
    0108 Core Count

    Before this version: You were advised to allocate at least six cores of CPU resources to the FineDataLink container.

    After this version: You are advised to allocate at least eight cores of CPU resources to the FineDataLink container.

    0121 Memory Resource Check

    New for FineDataLink projects:
    The system checks the total memory of
    Xmx + Off-heap memory + FineIO Read + FineIO Write + CodeCache configuration + Metaspace memory + 4 GB for the FineDataLink container. The value is advised to be less than or equal to the maximum available memory of the container.

    0122 Node Container - Memory Resource Check

    New for FineDataLink projects:
    You are advised to reduce the maximum available memory of containers or increase the server memory configuration, ensuring that the sum of the maximum available memory values of all containers on the server is less than or equal to the available server memory.

    0123 Node Container - CPU Resource Check

    You are advised to ensure that the sum of the maximum available CPUs of all containers divided by the actual server CPUs is less than or equal to four.

    1041 LogDB ConfigurationThe system checks whether a FineDataLink project uses the Elasticsearch component as the log storage service. You are advised to switch the log storage service to Elasticsearch to avoid performance issues and crashes.
