I'm not sure if we have seen an ROI. 

We look at ROI constantly. We put the amortized cost of Sumo Logic and New Relic right in the console that our service teams can look at. The ROI is good enough for us not to move away from Sumo Logic.

The troubleshooting part of Sumo Logic has solved a lot, e.g., if there is any downtime on the website. So, we have reduce our downtime by a lot with Sumo Logic because we can easily troubleshoot issues.

We have seen ROI. The product saves time. Because of it, we don't have to provide credentials for everybody to look at individual systems to find their logs.

We have seen improvement in our operational processes.
