Summary of Working with Application Insights graphs
Application Insights graphs enable ServiceNow customers to monitor key performance metrics and the overall health of their instance through time-series visualizations. These graphs refresh automatically every five minutes, providing up-to-date insights that help in analyzing trends, diagnosing issues, and proactively managing system performance during critical activities like system updates or high user traffic periods.

Overview graphs
The Overview tab consolidates metrics from Events, ECC Queue, and Session Info tabs, offering an aggregated instance-level perspective. Customers can:
- Analyze individual and combined metric trends over selectable time ranges (1, 7, or 30 days).
- Overlay diagnostic events to identify causation and correlation.
- Customize graph views by selecting specific metrics from the legend.
- Interact with graphs to view detailed metrics at specific points in time and drill down to node-level details.
- Narrow or shift time ranges interactively for focused analysis.
Detail graphs
Located in the Events, ECC Queue, and Session Info tabs, detail graphs provide node-level views of metrics with advanced functionality, enabling customers to:
- Compare metrics to median, 1-day moving average, and 95th percentile values to identify performance anomalies.
- Detect whether performance issues are isolated to specific nodes or widespread.
- Group nodes by performance similarity for clearer trend identification, especially when many nodes are present.
- Apply custom filters to focus on nodes meeting certain criteria, such as online status.
- Overlay diagnostic events to assist in root cause analysis.
- Interact with graphs to view detailed node or agent statistics and associated events within specific time windows.
- Sort, filter, and group tabular data beneath graphs to facilitate detailed data exploration.
Practical benefits for ServiceNow customers
By leveraging Application Insights graphs, customers gain a powerful toolset to visualize and understand the performance of their ServiceNow instances at both the aggregate and node levels. This enables proactive system health monitoring, faster identification of issues, and informed decision-making to maintain optimal performance and user experience.
View key performance metrics for your instance using Application Insights graphs.
Application Insights provides time-series data in a collection of graphs that help you visualize the performance and health of your instance. The graphs are automatically refreshed every five minutes.
Overview graphs
You can view a summary of the overall health and performance of your instance on the Overview tab. It provides in an aggregated instance-level view by combining metrics from the Events, ECC Queue, and Session Info tabs.
Use the overview graphs to do the following:
- Analyze how metrics have been performing over time individually and in relation to each other.
- View trends or patterns between different data sets by overlaying metrics and diagnostic events.
- Closely and proactively monitor the instance when performing any impactful activity such as a system update or during periods of heavy user traffic.
- Overlay diagnostic events to help you determine causation and correlation.
- Compare metrics or focus on a specific metric by selecting which graph lines to display from the legend above the graph.
- Change the time period by selecting a different day range from the date picker. The default value is 1 day, but you can also change the time period to 7 days or 30 days.
- View the details for all metrics at a point in time by pointing your cursor anywhere on
the graph.
View node-level details for a metric by pointing your cursor and selecting a data point. The corresponding detail graph on the Events, ECC Queue, or Session Info tab is displayed.
- Narrow the time range by selecting the left or right side of the time line below the graph and dragging across. Shift the time range by dragging this view along the axis.
Detail graphs
Each graph on the Events, ECC Queue, and Session Info tabs provides a detailed view of metrics for one or more nodes.
Use the detail graphs to do the following:
- Compare a specific metric to the median, 1-day moving average, or the 95th percentile value
- View trends or patterns by overlaying metrics and diagnostic events
- Determine whether performance degradation is happening on one node or across all nodes
- View detailed statistics for each node to monitor system health over time
Detail graphs include the same controls as overview graphs but provide additional functionality.
- See trends, issues, and system health for nodes and agents with similar performance values by selecting Group By Performance. If there are seven or more lines on the graph, this option is selected by default.
- Overlay diagnostic events to help you determine causation and correlation.
- Add a custom filter to display data for specific nodes. For example, display the average transaction time for nodes where the status is online.
- Compare the performance of different nodes to the 1-day moving average by selecting
which graph lines to display from the legend above the graph.
The 1-Day Moving Average line represents the average value across all nodes over one day.
- Change the time period by selecting a different day range from the date picker. The default value is 1 day, but you can also change the time period to 7 days or 30 days.
- View the details for an agent or node by pointing your cursor anywhere on the
graph.
Compare the metric to the following horizontal lines on the graph:
- Median: The middle value.
- 95th percentile: The 95th percentile value. A metric with a data point above this line is likely a cause for concern.
View a list of associated events or transactions within a 10-minute period by pointing your cursor and selecting a data point.
- Narrow the time range by selecting the left or right side of the time line below the graph and dragging across. Shift the time range by dragging this view along the axis.
The median, average, and 95th percentile values for each node are displayed in the table below the detail graph.
- To sort records in the list, select the column header.
- To filter the list using a value in a field, right-click in the field and select Show Matching or Filter Out.
- To group records in the list by label, select the column options menu and then select Group by.
- To filter records in the list, select the column options menu and then select Filter. Enter a condition and value.
