Sentry has integrated its error monitoring system with PagerDuty's automated escalation system to help users quickly resolve issues identified by Sentry. The integration allows for setting up fine-grain alert rules in Sentry and linking each Sentry issue to its corresponding PagerDuty issue, providing all necessary context for swift resolution. To use the integration, go to Settings, click on Integrations Page, follow the instructions, and set up custom alerts via PagerDuty.
