--- title: Transactions page: Find specific performance problems source: https://docs.newrelic.com/docs/apm/apm-ui-pages/monitoring/transactions-page-find-specific-performance-problems --- APM's **Transactions** page helps you identify [transactions](https://docs.newrelic.com/docs/apm/transactions/intro-transactions/transactions-new-relic-apm) that may be good candidates for fine-tuning performance problems or resolving errors. This page lists the selected app's transaction **Requests**, the top twenty transactions by percent of [wall-clock time](#wall_clock_time), and relevant [throughputs](https://docs.newrelic.com/docs/using-new-relic/welcome-new-relic/getting-started/glossary#throughput) (requests per minute or **rpm**). For [non-web transactions](https://docs.newrelic.com/docs/apm/transactions/intro-transactions/monitor-background-processes-other-non-web-transactions) (such as message processing, background tasks, and other processes and jobs that do not handle web requests), this page shows charts of CPU and memory usage. ## Types of transactions [#tx_types] > #### 💡 TIP > > To get a high-level overview of all your applications and services, use our [entity explorer](https://docs.newrelic.com/docs/new-relic-one/use-new-relic-one/ui-data/new-relic-one-entity-explorer). Depending on your selected application, the **Transactions** page may include a dropdown you can use to select from the [types of transactions available](#txn-type-dropdown). New Relic measures [processing time](https://docs.newrelic.com/docs/apm/applications-menu/features/request-queuing-tracking-front-end-time) by type of request ([web transaction](https://docs.newrelic.com/docs/using-new-relic/welcome-new-relic/getting-started/glossary#transaction) or [non-web transaction](https://docs.newrelic.com/docs/using-new-relic/welcome-new-relic/getting-started/glossary#non-web-transaction)). This may include: - **Web:** App server requests - **Non-web:** Other requests (operations, background tasks, etc.) The **Transactions** page also may include links to [transaction traces](https://docs.newrelic.com/docs/apm/transactions/transaction-traces/introduction-transaction-traces) and [key transactions](https://docs.newrelic.com/docs/apm/transactions/key-transactions/introduction-key-transactions). The types of information available will depend on your selected app and the type of request (web or non-web). ## Wall-clock time [#wall_clock_time] Wall-clock time measures "real-time elapsed" during a specific transaction. For example, let's say you're an engineer responsible for managing the checkout experience on an ecommerce site. You'd like to understand how long it takes for a customer to add an item to their cart. The transaction took 15 seconds to complete but one minute in the real world or on the "wall clock" for the customer. This discrepancy in time could be because the function had to wait for network calls or other inputs and outputs, and that waiting time isn't considered in the system's transaction time. New Relic uses wall-clock time for all the transactions and then sums that value across all of the transactions. In the above example, imagine that when a customer adds an item to their cart, the host has to make two requests to complete this work. One of these functions might take 3 seconds to complete, and the other takes 2 seconds, but because they occur simultaneously, the customer only had to wait 3 seconds. Because of this parallel work, you may see percentages over 100. For example, 100% would indicate that the execution time across all selected transactions equals the time expended when recording wall-clock time. ## View transactions [#tx_viewing] To view information about your app's transaction requests: 1. Do one of the following: - Go to **[one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > APM & services > (select an app) > Monitor > Transactions**. - Go to **[one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > APM & Services > (select an app) > Monitor > Transactions**. 2. If applicable: To change which available [types](#tx_types) of transactions appear, select the **Type**. 3. Select the [sort order](#sort-definitions), or keep the default. 4. Select the [type of view](https://docs.newrelic.com/docs/using-new-relic/user-interface-functions/view-your-data/select-chart-views) as a chart (default), histogram, or percentile, if available. 5. To view additional details, use any of the transaction [drill-down functions](#tx_functions). 6. To add a chart to a dashboard, mouse over the chart, then select the **Add to a dashboard** link that appears below it. If a chart's background is light red, this indicates a time period when an alert condition's [**Critical** threshold](https://docs.newrelic.com/docs/alerts/create-alert/set-thresholds/set-thresholds-alert-condition) has been breached. To view the [alert event details](https://docs.newrelic.com/docs/alerts/alert-event-management/view-alert-event-details) in [alerts](https://docs.newrelic.com/docs/alerts/overview), click the chart. For more information, see the documentation about [managing your dashboard](https://docs.newrelic.com/docs/query-your-data/explore-query-data/dashboards/manage-your-dashboard/). ## Use drill-down functions [#tx_functions] Use any of New Relic's standard [user interface functions](https://docs.newrelic.com/docs/new-relic-solutions/new-relic-one/introduction-new-relic-platform) to drill down into detailed information. The **Transactions** page has additional drill-down functions. **Change the displayed transaction Type** ![Screenshot showing the dropdown that allows you to choose other transaction types.](https://docs.newrelic.com/images/apm_screenshot-crop_dropdown.webp "trx-type-dropdown.png") If the **Type** dropdown appears above list of transactions, you can select your choice of transaction type. The available types depend on what transactions your application uses. **Select the type of performance measurement (Sort)** The **Sort** dropdown above the transaction list allows you to review transactions according to different measurements. This helps you identify good candidates for performance tuning or fixing errors. You can sort by: | **Sort option** | **Comments** | | ----------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Most time consuming (default) | Highest percentage of the app's total time used. This measures which transactions consumed the most time in total. This is calculated by multiplying the number of times the transaction is called by the time the transaction took to complete. A transaction could be short, but if it is frequently called, it would appear at the top of this ranking. | | Slowest average response time | Slowest individual transactions for the time period as averaged. This measures the slowest types of transaction. A transaction could be called only a few times, but if it is one of the longest transactions to finish, it would appear at the top of this ranking. | | Apdex most dissatisfying | Transactions with the highest percentages of user dissatisfaction levels for the response time of your web apps and services ([Apdex](https://docs.newrelic.com/docs/apm/new-relic-apm/apdex/apdex-measuring-user-satisfaction)). The [dissatisfaction level](https://docs.newrelic.com/docs/apm/new-relic-apm/apdex/view-your-apdex-score#apdex-dissat) is the difference between a perfect Apdex score (1.0) and your app's `apdex_t` ("tolerating") score, based on your [Apdex settings](https://docs.newrelic.com/docs/apm/new-relic-apm/apdex/change-your-apdex-settings). Transactions that have the highest (worst) percentages appear at the top of this ranking. | | Highest throughput | This measures the amount of [throughput](https://docs.newrelic.com/docs/using-new-relic/welcome-new-relic/getting-started/glossary#throughput), in operation requests per minute or **rpm**. (For web throughput, requests per minute is sometimes called pages per minute or **ppm**.) Transactions that have the highest number of requests per minute appear at the top of this ranking. | > #### 💡 TIP > > Depending on the transaction type you choose, different sort options may be available. **Mouse over summary information about a transaction** ![crop-tx-summary-details](https://docs.newrelic.com/images/apm_screenshot-crop_transaction-summary.webp "crop-tx-summary-details") To quickly view key pieces of information about the transaction, mouse over its name on the list. **Select detailed information about a transaction** ![Transaction details tab](https://docs.newrelic.com/images/apm_screenshot-crop_transaction-detail-tab.webp "icon-detail-tabs.png") To view detailed information, select a transaction from the list, then select **App performance** or **Historical performance**. You can also [view transaction traces](https://docs.newrelic.com/docs/traces/viewing-transaction-traces). **View transaction data in different visual formats** ![Screenshot showing selectors to change the chart.](https://docs.newrelic.com/images/apm_screenshot-crop_chart-selector.webp "chart_type_selectors.png") The **Transaction** page's **Top 20 transactions** chart and a selected transaction's **App performance** window include options to view data as a: - [Chart](https://docs.newrelic.com/docs/using-new-relic/user-interface-functions/view-your-data/select-chart-views) - [Histogram](https://docs.newrelic.com/docs/using-new-relic/user-interface-functions/view-your-data/histograms-view-data-distribution) - [Percentile](https://docs.newrelic.com/docs/using-new-relic/user-interface-functions/view-your-data/percentiles-compare-ranked-data) In addition, from the **Breakdown** table for a selected transaction, you can select the link to show or hide all segments of the breakdown data. **Show corresponding browser request data** In order to view browser information, you must [install the browser agent](https://docs.newrelic.com/docs/new-relic-browser/browser-settings). Then, to view corresponding [browser request](https://docs.newrelic.com/docs/browser/new-relic-browser/additional-standard-features/page-views-understanding-your-sites-popularity) data, use either of these options: - Select the **Browser drill-down** link if available. - Go to **[one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > Browser > (select an app) > Page views**. **Identify transaction segments with high call counts or time** ![Transaction segment with high call time count colorization](https://docs.newrelic.com/images/apm_screenshot-crop_apm-high-transaction.webp "APM-transaction-high-time-colorization.png") In a transaction's **Breakdown table**, the **Avg calls (per txn)** column may include colorized segment values. These indicate instrumented segments that have exceeded thresholds. - Yellow: Segment time is more than 10% of total transaction time and call count is higher than 10. - Red: Segment time is more than 10% of total transaction time and call count is higher than 20. ## Additional functions [#more_tx_functions] Here are some additional functions for the **Transactions** page's selected transaction. | **If you want to...** | **Do this...** | | ----------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | View transactions for operations and other background tasks | Change the **Type** to **Other transactions** (or a specific type listed), then select a specific transaction.
