FAQs (Frequently Asked Questions)

 

1. What is the cost associated with Synthetics Monitoring in New Relic?

The cost of Synthetics Monitoring in New Relic can vary depending on the specific plan and features you choose. New Relic offers different pricing tiers, and the cost typically depends on factors such as the number of synthetic monitors you need, the frequency of monitoring, and the locations from which the tests are run.

For more detailed and up-to-date information on the pricing, I recommend visiting New Relic’s official website or contacting their sales team to get a personalized quote based on your specific monitoring requirements.

2. Can Synthetics Monitoring replace real user monitoring (RUM)?

Synthetics Monitoring and real user monitoring (RUM) serve different purposes and are both valuable in monitoring an application’s performance.

Synthetics Monitoring involves simulating user interactions to monitor an application proactively from various geographic locations. It helps identify issues before real users are affected, and it’s useful for tracking uptime, response times, and overall availability.

On the other hand, RUM captures data from actual users’ interactions with your website or application. It provides insights into how real users experience your application, including their devices, browsers, and geographic locations. RUM can highlight user-specific issues and user behavior trends.

Both monitoring approaches complement each other and together provide a comprehensive understanding of an application’s performance and user experience.

3. How frequently should I run Synthetics Monitors?

The frequency of running Synthetics Monitors depends on your monitoring needs and how frequently you want to check your application’s performance and availability.

For critical applications or services, it’s common to run synthetic tests more frequently, even as often as every few minutes. This high frequency allows for quick detection of any issues or performance degradation.

For less critical applications, you might choose to run the tests less frequently, like every 15 minutes or half an hour.

Consider your application’s usage patterns, user expectations, and the potential impact of any downtime or performance issues when deciding on the monitoring frequency.

4. Can I simulate user interactions with different devices and browsers?

Yes, New Relic’s Synthetics Monitoring allows you to simulate user interactions with different devices and browsers. This capability is crucial for understanding how your application performs across various platforms and environments.

When creating synthetic tests, you can specify the device types (e.g., desktop, mobile) and choose from a variety of browsers (e.g., Chrome, Firefox, Safari) to simulate user interactions accurately.

By testing with different devices and browsers, you gain insights into potential compatibility issues and performance variations experienced by your users.

5. Are there any limitations to the complexity of test scripts?

While New Relic’s Synthetics Monitoring allows you to create custom test scripts for more advanced scenarios, there are some limitations to consider:

Execution Time: Synthetic tests are designed to run within specific time limits. If your test script takes too long to execute, it may not complete successfully.

Third-Party Dependencies: The test scripts should be written with consideration for any third-party dependencies, such as APIs or external services, to ensure the tests can execute properly.

Single Page Applications (SPAs): Testing SPAs with complex JavaScript frameworks may require additional configuration and considerations to ensure accurate monitoring results.

Geographic Testing Locations: While New Relic offers a variety of testing locations, the availability of specific locations might have limitations based on your subscription tier.

Always test and validate your scripts during the setup process to ensure they function as intended and account for any possible limitations.

Remember that New Relic’s support and documentation can provide additional insights into the capabilities and limitations of Synthetics Monitoring to help you make the most of the feature.
