Your Apdex score measures users' satisfaction with the response time of your web applications and services. The dissatisfaction score is the difference between a perfect Apdex score (1.0) and your app's
apdex_t ("tolerating") score based on your Apdex settings.
To help identify and troubleshoot Apdex level changes that indicate poor customer experiences with your site, use any of these resources:
- New Relic's user interface (explained in this document)
- New Relic REST API
- Alert notifications
- Videos at learn.newrelic.com about understanding your Apdex data with APM and creating Apdex queries with Insights
Apdex applies only to web apps or services. The Apdex chart in the UI appears blank for non-web apps.

- 1.0: All responses are satisfactory.
- Tolerating responses half satisfy a user. For example, if all responses are
Tolerating,then the Apdex score will be 0.50.
- 0.0: None of the responses are satisfactory.
To view the Apdex score for your web apps or services:
- Go to rpm.newrelic.com/apm > (select an app) > Overview.
- From the APM Overview page, review the Apdex score chart.

View transactions with highest Apdex dissatisfaction
Transactions at the top of New Relic APM's Transactions page often are good candidates for performance tuning or fixing errors. To view transactions with the highest Apdex dissatisfaction percentage:
- Go to rpm.newrelic.com/apm > (select an app) > Transactions.
- From the Sort by options, select Apdex most dissatisfying.
- Specific web transaction: To view details about a specific transaction, select its row.
- All web transactions: To view a list of Apdex dissatisfaction percentages or export a file with comma-separated values, select Show all transactions table.
By definition, the All transactions row always contributes 100% of the app's total dissatisfaction, even if no responses are dissatisfying (100% of zero is zero). In this situation, 100% does not mean that all of your transactions are dissatisfying. The sum of all the other values in this column is 100%.
To focus on Apdex levels for specific transactions, you can also:
- Configure transaction traces to capture
apdex_f, which is four times your app server's
- Create key transactions to track changes in Apdex values for specific transactions that are important to your business, such as signups, purchase confirmations, searches, site logins, etc.
