What is a Sensu plugin?
Sensu plugins provide executable scripts or other programs that can be used as Sensu checks (i.e. to monitor server resources, services, and application health, or collect & analyze metrics), Sensu handlers (i.e. to send notifications or perform other actions based on Sensu events), or Sensu mutators (i.e. to modify event data prior to handling).
For more about Sensu plugins, please refer to the Plugins reference documentation.
