Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"The stability of New Relic APM is very good.""The most valuable feature is the ability to receive in-depth information about applications. It can detect a lot of important information.""The most valuable feature is application monitoring.""The breakdown of the response time of different components and getting in-depth details of the slow component are the most valuable features. It is easy to use, and it gets the job done.""Working with the solution is very easy. It's user-friendly.""The monitoring so far has been good and we are happy with it.""There are many valuable features in New Relic APM. We developed some software applications and we are able to monitor the errors very easily. Their log security retention is very good.""It does everything we wanted it to do."

More New Relic APM Pros →

"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis.""There are custom reports available along with the inbuilt reports.""This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build.""The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."

More AlertSite Pros →

"We were able to integrate with the messaging tool, Slack, which meant that we got notifications whenever something was not quite right."

More New Relic Synthetics Pros →

"The solution could improve by having more network monitoring features, such as for all the infrastructure.""New Relic APM could improve error debugging and the correlation with the logs. We are receiving some alerts or alarms but we need to correlate with the error log, but it is difficult if it is more than seven months retention period, it is hard to trace. We need this especially for getting historical information.""The older view is much better than the new view that they have. We'd like to go back to that previous version. The user interface just isn't as nice as it used to be.""There has been some problem with the agent, and it is just not working well. It is not able to record information with the application server. They have been able to fix the issue, but it took quite a long time. This is the main issue in the APM products and also in New Relic. The mobile application monitoring has been pretty difficult to set up and also quite expensive. It should be a little bit easier and cheaper. Because it is pretty difficult and expensive, many customers don't take it.""How granular I could go down at looking at certain data, especially related to the operations, is limited.""New Relic APM can improve the information when we dig deeper to check a problem. There should be more detailed information provided.""It would be nice if there were pre-made dashboards.""It is very difficult to award the service level cycles at an endpoint level."

More New Relic APM Cons →

"It is not compatible with all of the product platforms that we use.""I would like the ability to get more data points with regard to some of the unique requirements that we have.""AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed.""What needs improvement in AlertSite is the documentation, particularly the lack of documentation. If there's a specific activity you want to do, you can't even find information on how to do it, so you have to contact the AlertSite support team to assist you, and only then would the issue be resolved. At the moment, it's not easy to find or get full documentation on how to deal with different issues. You always have to go back to AlertSite support and get help. The documentation for AlertSite could be improved and it's what I'd like to see in the next release of the tool because at the moment, the documentation isn't complete, so you'll have to contact support, but contacting support isn't an issue because the team responds to you quickly."

More AlertSite Cons →

"There are certain features that are not supported in New Relic, such as CATSEARCH, which allows you to do a full-text search."

      • Sets alert thresholds that are both static and dynamic.

    New Relic Synthetic Monitoring is a next-gen suite of scripted, automated tools developed to monitor users’ API endpoints, critical business transactions, and websites. Users are able to replicate consumer traffic and intuitively identify and remediate downtime and unsatisfactory performance regarding crucial endpoints. This ensures that there is no defect in productivity or performance and so clients’ services are never affected. New Relic Synthetic Monitoring enables users to continually monitor API endpoints or websites to ensure they are working properly and content is always available.

    Quality Testing Processes and Monitoring

    New Relic’s browser testing protocol sends valid Selenium-powered Google Chrome browsers to test sites to establish that an organization's content is always available to anyone, anywhere. Scripted browsers are employed to test for user flow anomalies or to beta-test complicated processes such as: adding items to a cart on ecommerce sites, joining member portals, signing up for newsletters, searching for embedded content on a website, or testing backend with API monitors to run scripted tests for any API endpoint.

    Synthetic monitoring will break down the results of each check into metrics, giving users full visibility to better discover patterns and potential reasons for unsatisfactory performance. The solution will store all monitor results to enable users to visualize the exact point where a website broke down. Alerts will advise users when an API endpoint or website became inaccessible. Users are also able to widen the geographical scope and closely monitor internal websites by creating private locations.

    New Relic is able to store all monitor results for up to thirteen months to give users a historical view of results for over a year. An important feature to remember is that the test data collected using New Relic Synthetics is synthetic data; it does not reflect any actual human interaction and contains no personal critical information.Therefore, there are no data protection or privacy concerns.

    Why Synthetic Monitoring is Beneficial

    • Quickly determine the root and cause of any issue. New Relic Synthetics will determine if there is a latent third party application, poor backend or infrastructure issue, AWS location, or overall network issue.

    • Synthetic monitoring can be embedded into CI/CD pipelines and build automation to instantly track efficiency and determine the productivity of every deployment.

    • Ensures a better understanding of failures by associating the availability and performance of all endpoints to the basic applications and core infrastructure.

    • API tests monitor API endpoints using a progressive got module to interact internally to make HTTP calls to an organization's endpoints and legitimizes the results.

    New Relic Synthetics Features

    • Precise results: New Relic stores all results for up to thirteen months. Users get a clear snapshot to facilitate a better understanding of website performance and availability, and help discover specific issues.

    • Charting: Users can use New Relics charting feature to compare load time against real users and synthetic monitors. Users can view trends and determine if an issue is evident in synthetic monitoring or caused by other anomalies.

    • Integrates with popular analytics platforms: Users are able to block or unblock any service that may have been noticed by default settings. New Relic is designed to ignore scripts from today’s popular analytics services (such as Google Analytics) to ensure the chosen analytics tools will still receive the identical data, even though there are thousands or monitors checking your website each month.

    • Browser monitors: New Relic uses scripted and simple browser monitors to not only ensure the host is functioning properly; it will actually load the complete content of each page in a completely virtualized Google Chrome browser (Selenium-powered) to complete testing that mimics actual user actions.
