We have used Sentry for a long time with JavaScript. The main issues for us are:
* Obese JavaScript code. We had to write our own custom code to log events.
* Aimed at large scale companies. We only have 1000s of users, and we care about each individual exception, but I think it is really aimed at consolidating large numbers of events.
* Meaningless percentages on data. Tagged data is processed, but the end percentage value has little meaning e.g. send through 1000 similar events, with 1 event with a tag with value X, and 1 event with a tag with value Y, and 998 with no value. Sentry reports 50% X and 50% Y!
But they have given us really excellent service, especially given we are not paying enterprise rates.
Edit: also we are not in a US timezone, which makes the UI weird. And I do love the email integration: have a bug, get an email, fix it.
