We shortly tried using sentry some time ago, maybe something has changed since then, but these were our problems:
The default crashpad backend of sentry does not allow for preprocessing of the error events, since its out of process (since the before_send hook can’t be called). Without filtering, you would just get spammed with errors not related to your plugin.
Using breakpad instead, we had to disable sentry for a lot of hosts in order for the plugin to work at all. Then there also was an interaction with some of the SSL Plugins, that would cause sessions to crash only when both one of these plugins and one of our plugins with sentry were loaded in the session.
Maybe there is a way to make sentry work with the crashpad backend or another backend.
