    Summary of Application Insights detail graphs and metrics

    Application Insights detail graphs provide node-level views of individual performance metrics in ServiceNow instances. These graphs cover events, ECC queue status, session information, semaphore queues, and database performance. However, starting with the Zurich release, Application Insights is no longer deployed, enhanced, or supported. Customers are advised to transition to the Instance Observer product available in the ServiceNow Impact packages and consult their Account team for assistance.

    Key Metrics and Their Sources

    The detail graphs are grouped into three main categories, each sourced from specific tables and keys in the ServiceNow database:

    • Events Detail Graphs: Metrics like the number of events processed and logged are sourced from the sysclusternodestats table, focusing on processed and logged events keys.
    • ECC Queue Detail Graphs: These metrics monitor the state of entries (Ready, Processing, Processed) in both input and output ECC queues, with data drawn from the eccqueuestatsbyeccagent table.
    • Session Information Detail Graphs: Provide insights into transaction response times, transaction load, logged-in users, semaphore queue depths, semaphore rejections, and database performance. These metrics come from various keys in the sysclusternodestats table and include semaphore and database statistics.

    Practical Implications for ServiceNow Customers

    • These graphs enable monitoring of instance performance at a granular, node-specific level, helping identify bottlenecks or issues in event processing, ECC queue handling, session transactions, and database responsiveness.
    • Understanding semaphore queue depths and rejections can highlight API integration and messaging queue bottlenecks.
    • With the deprecation of Application Insights in Zurich, customers should plan to adopt Instance Observer for ongoing performance monitoring, ensuring continued support and feature enhancements.
    • Engaging with the ServiceNow Account team is recommended to explore Impact packages and facilitate migration from Application Insights.

    The Application Insights detail graphs provide views of individual metrics at the node level.

    Starting with the Zurich release, Application Insights is no longer deployed, enhanced, or supported. It is recommended to evaluate the Overview of Instance Observer product available with the ServiceNow Impact packages. Work with your Account team to review Impact packages.
