There are a few valuable features: * the alerting system * the Monitoring Insight * the support from the wider Eggplant team Overall, the key features for us are the usability, timeliness of it, and the flexibility. It's also really important that Eggplant Performance provides highly configurable performance tests that replicate real-world conditions, because that's exactly what we're trying to do. We're using Eggplant to mimic customers going to our system, buying a product, and looking at documentation. It's really important that we can mimic that. We can't do so manually because the overhead on that is far too high. We need confidence in a solution that does exactly that; mimics an end-user. We do it hundreds of times a day because if that end-user experience is a problem, we need to know about it and deal with it. When we went to market and looked at several competitors, that was one of the things that was crucial for us. To be fair, a number of the competitors could do that, but the way Eggplant does it was one of the reasons why we chose it.
