Development Environment Observability with Sentry

At Sentry, they introduced error monitoring into their developer environment to improve observability and understand the health of their development tools. They found that local development environments can be fragile, requiring time and effort to troubleshoot issues. By instrumenting their Bash scripts with Sentry, they gained visibility into what was happening in their development environment, allowing them to be alerted when something went wrong. This enabled them to respond quickly to issues, helping engineers investigate and fix problems more efficiently, and reducing the likelihood of tooling regressions being worked around.
