    Key Features

    • Current CPU Usage: Displays the percentage of processing power consumed by the application. High CPU usage may degrade performance and slow response times, so monitoring this helps identify bottlenecks and optimize application efficiency.
    • CPU Usage Trend: Shows CPU consumption over selectable time frames (past 2 hours, 24 hours, or 15 days). Tracking trends enables proactive performance management and resource optimization to enhance user experience.
    • Current Memory Usage: Indicates the percentage of RAM used by the application. Monitoring memory usage prevents performance degradation, system instability, and crashes by ensuring adequate resource allocation.
    • Memory Usage Trend: Displays how memory consumption changes over time, aiding in capacity planning and improving application reliability and productivity.
    • Current I/O Read: Measures data retrieval from storage devices, which affects application speed and responsiveness. Monitoring I/O read helps detect performance differences across application versions.
    • I/O Read Trend: Tracks historical data retrieval activity over selectable time frames, providing insights into potential bottlenecks.
    • Current I/O Write: Measures data storage operations impacting performance and data integrity.
    • I/O Write Trend: Shows historical write operations to assess performance and data management over time.

    Practical Application

    ServiceNow customers can select different time ranges for performance data to analyze short-term or long-term trends. This flexibility supports troubleshooting, capacity planning, and continuous optimization of installed applications. By actively monitoring these metrics, customers can enhance application responsiveness, prevent downtime, and ensure optimal resource utilization aligned with business needs.

    The installed application performance section provides information on CPU usage, CPU usage trends, memory usage, and memory usage trends. This information is important for optimizing system performance, resource allocation, capacity planning, and troubleshooting.

    CPU usage - <time>
    Note:
    The <time> range of the performance data can cover the past 2 hours, 24 hours, or 15 days, depending on the timeframe you select from the provided drop-down list in the Performance section.
    		 Trend of how much processing power is being used to execute the application's instructions and how your system's CPU usage changed over a specified period.
    Note:
    By tracking CPU usage over time, you can identify potential performance issues and take steps to optimize system resources and improve the overall digital end-user experience.
    Current memory usage
    Amount of memory (RAM) consumed by an application in percentage.
    Note:
    High memory usage can result in degraded application performance, slower response times, and potentially lead to crashes or system instability. Monitor memory usage to optimize resource allocation and capacity planning, ensuring that applications have sufficient resources to meet user demands.
    Memory usage - <time>
    Note:
    The <time> range of the performance data can cover the past 2 hours, 24 hours, or 15 days, depending on the timeframe you select from the provided drop-down list in the Performance section.
    		 Trend of how much memory (RAM) your application or system is using over a specific period.
    Note:
    By optimizing memory usage, you can reduce the risk of downtime, improve application performance, and maximize employee productivity.
    Current I/O read Retrieval of data from storage devices, impacting application speed and responsiveness.
    Note:
    Monitoring I/O read can reveal performance differences between different versions of the app.
    I/O read - <time>
    Note:
    The <time> range of the performance data can cover the past 2 hours, 24 hours, or 15 days, depending on the timeframe you select from the provided drop-down list in the Performance section.
    		 Tracks the history of data retrieval operations, providing insights into performance trends and potential bottlenecks.
    Current I/O write Process of storing data to storage devices, influencing application performance and data integrity.
    I/O write - <time>
    Note:
    The <time> range of the performance data can cover the past 2 hours, 24 hours, or 15 days, depending on the timeframe you select from the provided drop-down list in the Performance section.
    		 Tracks the history of data storage operations, facilitating performance analysis and data management assessment.
