Using Sentry to monitor exceptions

Sentry is a tool that eases the process of monitoring exceptions and also provides insights into the errors that the users of the application face while using it. It is highly possible that there are errors in log files that get overlooked by the human eye. Sentry categorizes the errors under different categories and keeps a count of the recurrence of errors. This helps in understanding the severity of the errors on multiple criteria and handling them accordingly. It has a nice GUI that facilitates all of these features. In this recipe, we will set up Sentry and use it as an effective error monitoring tool.
