- The egress job runs through WorkerHelper.getEgressRecoveryJob(), like
the cleanup jobs, instead of a direct service call from the queue
- Toggling egressCheckEnabled resets the egress state and removes any
pending recovery job
- Probes resolve and pass the proxy, so http targets honour the global
proxy as monitors do
- PingProvider keeps IPv6 addresses intact instead of truncating at the
first colon
- Egress targets are parsed by one function shared by the validator and
the probe; malformed addresses such as unbalanced brackets are rejected
- Notification id pattern drops the /i flag, which produced an invalid
OpenAPI pattern
- EgressState findSingleton reads before it writes, so a read no longer
bumps updatedAt
- "disabled" is a distinct assessment result and is cached like any other
- Concurrent failures share an in-flight assessment for as long as it
runs, then reuse the settled result for 5 s
- The recovery job row is only removed if nobody rescheduled it since
this run claimed it, so a concurrent new episode keeps its job
- Deleting a notification removes it from egressNotifications

Checkmate backend
The backend service for Checkmate, an open source uptime and infrastructure monitoring application
This directory contains the backend of Checkmate, which handles data processing, storage, and API services for the Checkmate monitoring tool. The backend is responsible for managing uptime checks, handling real-time alerts, and storing historical monitoring data.
Checkmate's backend is designed to be lightweight and scalable, ensuring reliable performance even with a high number of active monitors.
