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 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.

Figure 18.3. Resource Utilization

Contains basic information about Worker and operating system.

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.

Figure 18.5. Running Jobs Chart

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.

Figure 18.7. CPU Load

Running jobs panel lists currently running jobs, 10 most recent runs are displayed.

Status history panel displays node statuses history since restart of the Server.

Figure 18.9. Status History

Contains information about license.

Figure 18.10. System

This panel lists info about activities on files performed by users. The list displays a timestamp of an event, username, address and name of the method.

Figure 18.11. Users' Accesses panel

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.

Figure 18.12. Status

Provides information about CloverDX Server utilization of operating system resources.

Heartbeat panel displays a list of heartbeat events and their results.

Figure 18.14. Heartbeat

Threads panel lists Java threads and their states.

Figure 18.15. Threads

Quartz panel lists scheduled actions: their name, description, start time, end time, time of previous event, time of next event and expected final event.
