Cabot is a self-hosted infrastructure monitoring and alerting platform originally developed by Arachnys Information Services.
The application was designed to combine straightforward service monitoring with incident notifications and basic on-call alerting, providing some of the capabilities associated with larger commercial monitoring and incident response products.
Cabot allowed administrators to monitor websites, backend services and infrastructure metrics without developing a dedicated monitoring system. Existing Graphite and statsd metrics could be used to determine whether applications were operating within acceptable conditions.
The system also supported grouping checks into logical services, allowing alerts to represent the health of an application rather than simply reporting individual server failures.
Cabot is no longer actively maintained. Its developers have explicitly requested new maintainers to take responsibility for the project. Although its source code remains available, it should not be recommended for new deployments without carefully assessing its dependencies, security and compatibility with current systems.
This is free and open source software.
Key Features
- Monitors websites, application endpoints and infrastructure services.
- Uses existing Graphite metrics to evaluate service health and operational thresholds.
- Checks Jenkins jobs and web endpoints for failures.
- Groups related monitoring checks into logical services.
- Organises monitored infrastructure into instances and service dashboards.
- Supports alert thresholds for identifying degraded performance before complete service failure.
- Provides a web-based interface for configuring monitoring checks and services.
- Supports alerting staff responsible for responding to incidents.
- Sends notifications through email, telephone and SMS integrations.
- Includes historical integrations with HipChat and other external communication services.
- Allows teams to use monitoring data collected by existing systems rather than deploying separate collectors for every check.
