Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
The Performance page for a web application displays engagement metrics and performance metrics, such as sessions and page views, response time, page load time, and failed web requests.
{#web-app-health-form__table_r4m_pkr_bgc__entry__2}

| Field | Description |
|-|-|
| Started Sessions | Total number of active user sessions for the application over the last 2 hours, specifically the latest 5 minutes. Note: Active user sessions information is vital for determining the server load. It also helps you to determine a suitable time for server maintenance. |
| Average session duration | Average amount of time spent according to user in the application over the last 2 hours, specifically the latest 5 minutes. It's calculated by dividing total time spent across sessions by the total number of users. |
| Page views | Frequency with which the users access or view a specific page within the application. Each visit to a page is recorded as one page view, whether it is by a first-time visitor or a returning user. |
[Table 1. Web application engagement metrics]

Note:  
Web application performance metrics are available for the previous 2 hours, 24 hours, or 30 days. Select the required time window from the drop-down list to update the visualization.
{#web-app-health-form__table_mrg_fpf_4wb__entry__2}

| Field | Description |
|-|-|
| Average response time | Total time taken to respond during the selected time period. |
| Average page load time | Average amount of time it takes to load the page, from initiation to load completion during the selected time period. |
| Average DNS lookup | Average amount of time it takes for a Domain Name System (DNS) lookup to be completed during the selected time period. A lower average DNS lookup time is desirable because it contributes to faster web page loading and improved overall internet performance. |
| Failed web requests | Set of all requests that either return an error code or an HTTP 408 status code or fail to return a success code during the selected time period. |
| Successful web requests | Number of times the HTTP requests made by the client (such as a web browser) to a server that result in a positive and expected response. |
| Availability | Measure of the system's operational performance and its ability to be accessible and usable when needed. It's typically expressed as a percentage, representing the proportion of time the application is functional and available for use. |
