Configuration uses an intuitive Ruby DSL, allowing Ruby developers to define monitoring rules without learning a new syntax, as shown in the extensive config examples in the README.

Supports monitoring of CPU usage, memory consumption, file modification times, and running duration with configurable thresholds, enabling detailed process health validation.

Structures processes into applications and groups for manageable supervision of related daemons, as demonstrated in the group and application-level config options.

Offers custom stop commands, signal sequences with timeouts, and output redirection without shell tricks, providing fine-grained control over process lifecycle management.
