The Resources page displays information about resources and performance of the CloverDX Server. The information is grouped in several panels and refreshed every 10 seconds. The following panels are displayed by default:

    By clicking ActionsShow details, you can display hidden panels with additional details which may help with troubleshooting.

    Instance Indicator

    Instance Indicator is a small area located in the upper left corner of the GUI to which you can assign a unique color and label. This way, when working on multiple Server instances, you can easily distinguish between them.

    Instance Indicator is shown only when either webGui.instance.color or webGui.instance.label is set.

    Resource Utilization

    Resource Utilization panel shows the amount of used System memory, System disk swap Server Core heap memory, Server Core non-heap memory, Worker heap memory and Worker non-heap memory.

    Worker and System

    Contains basic information about Worker and operating system.

    Performance Tab

    The Performance tab displays three line charts: Running jobs, Heap memory and CPU load. By placing a mouse over the charts, you can see a detailed tooltip of a selected point in time. For better readability, you can enable/disable individual lines in the graphs by clicking their label below respective graphs. You can select the time interval by mouse scroll wheel or by using the slider at the bottom of the screen. The slider allows you to set the start and the end of the time interval individually. By default, the maximum time interval for the charts in Performance tab is 24 hours. The value can be changed using the cluster.node.sendinfo.stats.interval property.

    Running Jobs

    This line chart displays the number of currently running jobs.

    Heap Memory

    The Heap memory chart displays the amount of used up Server and Worker heap memory.

    Note that the heap memory is constantly oscillating, even in idle state, since it is periodically managed by JVM garbage collector (i.e. the temporary data required for running CloverDX Server and Worker is periodically removed from/allocated to the heap memory).

    CPU Load

    The CPU chart displays information about Server Core, Worker and System CPU load.

    Classloader cache

    Classloader cache lists all currently cached classloaders. The classloader cache may be empty as classloader caching is disabled by default.


    Status panel displays current node status since last server restart. It displays current server status, exact Java version, exact CloverDX Server version, way of access to database, etc.
