Performance Metrics of Web Transaction (Browser)

Interpret Web Transaction (Browser) Metrics

In today's modern IT environment, it is super critical to monitor real end-user interaction and determine if your applications are running optimally. Moreover, it's also important to measure end-user experience from global locations. A Synthetic Monitor captures the availability and performance of your web transactions using an actual web browser like Firefox or Chrome. The feature uses a robust recorder tool to record web interactions and playback the same via real browser (Firefox or Chrome) to check how an end-user would experience it. Site24x7's Web dashboard has a custom status banner, which identifies the various configured monitors by segregating them based on their operational status and state. You can also view the number of operational monitors and alert credits remaining in your account. By clicking the "+ Buy More" button, you can purchase additional monitors and alert credits. Metrics like availability and performance are presented in an easy to understand graphical and tabular layout. Key metrics like Transaction Time, Page Load Time are captured from various locations and graphically interpreted for easy assimilation. You can share the monitor details via an email. Email can be sent to only those verified users who have agreed to receive emails from Site24x7.

Quick Summary and Events Timeline

A quick summary gives you insight into metrics like: Availability, Page Load Time, Transaction Time, Number of Downtimes and Downtime Duration and the SLA status. Events timeline widget records all the past events of your selected monitor for a selected time range. You can identify/decode various events from the past, which includes Down, Critical, Trouble, Maintenance, Suspended, or Anomalies. Each event are color coded for easy identification. Events can be drilled down to extract maximum data and facilitate easy troubleshooting. You can also track the actual outage period and the total outage duration during a specific block of time.

Following results from monitoring checks decide a Web Transaction (Browser)'s operational status:

Monitor Status	Status Icon	Conditions Affecting Monitor Status
UP		All monitor checks were successful
TROUBLE		Content check failure
DOWN		Unable to load the resources.  When the element is not present / visible on the web page. Content check failure
CONFIGURATION ERROR		Monitor is  configured incorrectly during initial set-up

You can gather deep insights on the following performance metrics:

• Transaction Time (ms): It defines the time taken to finish the entire recorded transaction, from the first step to the last step. The transaction time is a combined calculation of the response time and the think time. The Think time acts as a buffer or a wait time before starting the next step of the playback. Think Time is mainly required in steps involving AJAX calls.
• Transaction Time by Location (ms): It indicates the average location based time taken to complete a transaction for your recorded steps. Transaction time metrics of the Web Transaction (Browser) are presented in a graphical format. Average Transaction time and Average Transaction time by Location data are presented in a tabular layout for easy assimilation.
• Page Load Time (ms): It defines the total time taken to load the HTML and all its associated components including JavaScript and images, for an individual step in the transaction. Page Load Time provides the average value for the segmented time period.
• Availability & Page Load Time by Location (ms): It offers a graphical and tabular interpretation of the availability and average location wise page load time data in milliseconds.

Apdex Score

With our RUM integration widget, you can instantly use the Apdex industry standard to measure the satisfaction of a user using your application or service, you can understand how your applications are performing from your users’ perspective, i.e, “Satisfied”, “Tolerating” or “Frustrated”. The time period can be chosen from the History Data for the section.

Apdex Score is a measure of the end user customer satisfaction levels. Apdex Score can be classified as follows:

• Apdex score > 0.9 means Satisfied.
• Apdex score > 0.5 & <0.9 means Tolerating.
• Apdex score < 0.5 means Frustrated.

Transaction Time

The transaction time is a combined calculation of the response time and the think time for each individual steps in a recorded transaction. The think time acts as a buffer or a wait time before starting the next step of the playback. This is mainly required for steps involving AJAX calls, as we need to provide the time for the AJAX call to complete before the start of the next step.

The Transaction Time graph provides you the entire time data (in milliseconds) taken to finish the entire recorded transaction, from the first step to the last step. The graph is calculated by plotting time period against the total transaction time. You can obtain custom graphs by specifying the granularity as raw, hourly, or daily. Further you can filter out the three point, five point moving averages and also the 95 percentileby selecting the appropriate legends. Percentiles in Site24x7 can be used to find outliers. The 95th percentile is the value which is greater than or equal to 95% of the observed values of your polled data during the selected time range. In other words, 95% of the responses were faster than this value. The graph also lets you zoom in and extract data from the graphical spikes.

Transaction Details

With transaction details you can analyze the performance of your site with the help of detailed options like screenshots of each step, step time, page load time, the step name, resource-level waterfall chart for each page, and console errors that were raised in each step. Screenshots can be used to analyze how each step has performed and how the website has loaded. Step time helps you analyze the time taken for page load and the time taken by the actions involved in specific steps. Page load time helps to analyze the time taken by each page in the transaction.

Waterfall Chart

Webpage resource-level waterfall charts are valuable tools for helping customers understand performance issues by providing a visual representation of how a web page loads and the resources involved in the process.

You can view the waterfall chart by clicking on the Resources link. waterfall chart helps to analyse the performance of each component on a page. The waterfall chart provides the following information:
