Overall Satisfaction with New Relic

The tool is used in our company just by the IT department that I belong to.

We mostly use it to check if any problems occur on the user's browser. Given that we are a worldwide shipping company and our website is browsed by any and every device out there, it's really hard to run a proper test for all of them, so having a feedback on the errors occurring on the user's browser is a very important information for us. The ability to drill down the problem and understand on which browser they occur is invaluable.

Moreover, we integrated a lot of partners on our website, third party pixel, etc. We can easily spot any bugged release they made, seeing the increasing number of errors and easily finding the sources.
  • Having a overview of the errors occurring on browser, having the ability to drill down by browser, see the exceptions detail and source.
  • Having an overall measurement of the load page time, rendering time, and other important KPI in the site speed analysis.
  • Beside having a different interesting look at the data, sometimes it could be helpful to have more interconnections between those data. Things like having a look at the throughput split by countries, or having a look at the page loading time split by device or browser could be a significant improvement.
  • Most data are actually overlapping with other industry-standard tools like Google Analytics. That's not a real con of the tool, but probably some more tech detail should be added to differentiate from a more marketing-focused tool.
  • Well, it mostly saved us tons of problems with final users as we can discover (and fix) issues pretty early, even if they don't depend directly from our website (like third party pixels). Hard to calculate a ROI, but it helps improving the feeling that our website is pretty much bug-less in our customers
  • The analysis available for page load waterfall in the single sessions helped a lot to understand a few hidden sub-optimization available for browser/device sometimes hard to test in house under real conditions
We choose to buy New Relic Browser because from an IT point of view it gives you much more tech insight than Google Analytics or other similar tools. The tech view including JavaScript errors and session trace gives invaluable information to IT, something that no other product seems capable of doing at the time of choice.
The scenario where NR Browser really stands up is about issues discovering. Monitor if all the third party pixels works fine along side the core website execution would be a nightmare without this tool.
Having a more user behavioral look at the data is probably pointless: other tools like GA is more suited for this purpose. For example analizing the traffic hitting certain part of the website, where does this traffic comes from, etc.
