This page has instructions for installing the Sumo App for JMX and descriptions of each of the app dashboards. 

Install the App

To install the app:

Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.

  1. From the App Catalog, search for and select the app. 
  2. Select the version of the service you're using and click Add to Library.
  1. To install the app, complete the following fields.
    1. App Name. You can retain the existing name, or enter a name of your choice for the app.

    2. Data Source. Select either of these options for the data source.

      • Choose Source Category, and select a source category from the list.

      • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. Example: (_sourceCategory=MyCategory).

    3. Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
  2. Click Add to Library.

Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization. 

Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but with a bit of time, you'll see full graphs and maps. 

Dashboard Filter with Template Variables

Template variables provide dynamic dashboards that rescope data on the fly. As you apply variables to troubleshoot through your dashboard, you can view dynamic changes to the data for a fast resolution to the root cause. For more information, see the Filter with template variables help page.

JMX - Overview Dashboard

The JMX - Overview dashboard provides a quick summary of CPU and memory usage by different deployments. It also shows key statistics like JVM uptime, process versus system CPU load, committed versus used memory, objects collected by GC, and time taken by the last GC run server-wise.

Use this dashboard to:

  • Understand the overall health of your java virtual machine.
  • Monitor the number of open file descriptors. If the number of open file descriptors reaches maximum file descriptor, it can cause IOException: Too many files opens.
  • Gain insight into Garbage collection and its impact on CPU usage and memory.
  • Understand the dynamic behavior of threads. 
  • Understand the behavior of class count. If class count keeps on increasing, you may have a problem with the same classes loaded by multiple classloaders.

JMX - Memory

The JMX - Memory dashboard shows the percentage of the heap and non-heap memory used, physical and swap memory usage of your java virtual machine.

Use this dashboard to:

  • Gain insights into Heap and Non-Heap memory usage.
  • Review Physical and swap memory usage.
  • Review pending object finalization count which when high can lead to excessive memory usage.

JMX - CPU

The JMX - CPU dashboard shows the process and system CPU usage. It also shows the operating system information of your java virtual machine.

Use this dashboard to:

  • Gain insights into the process and system CPU load.
  • Review the CPU processing time.

JMX - Garbage Collector

The JMX - Garbage Collector dashboard shows key Garbage Collector statistics like the duration of the last GC run, objects collected, threads used, and memory cleared in the last GC run of your java virtual machine.

Use this dashboard to:

  • Understand the garbage collection time. If the time keeps on increasing, you may have more CPU usage.
  • Understand the amount of memory cleared by garbage collectors across memory pools and its impact on the Heap memory.

JMX - Thread

The JMX - Thread dashboard shows key information about the number and type of threads deadlocked, peak, and GC threads of your java virtual machine running on the deployment.

Use this dashboard to:

  • Understand the dynamic behavior of the system using Peak, Daemon, and current threads.
  • Gain insights into the memory and CPU time of the last executed thread.

JMX - Memory Pool

The JMX - Memory Pool dashboard provides key information about the memory pool usage, peak usage, collection usage, garbage collection across various memory pools of your Java virtual machine. 

Use this dashboard to:

  • Gain insights into memory usage across different memory pools.
  • Gain insights into garbage collection impact on different memory pools.
  • Understand Peak usage and collection usage of different memory pools.

JMX - Class Loading and Compilation

The JMX - Class Loading and Compilation dashboard shows key information about the rate of total loaded class, compilation time, unloaded classes of your java virtual machine.

Use this dashboard to:

  • Gain insights into the behavior of class count. If class count keeps on increasing, you may have a problem with the same classes loaded by multiple classloaders.
  • Gain insights into time spent by java virtual machines in the compilation.
