Sensu
|
|
-----
|
|
`Sensu <https://github.com/sensu>`_ was written as a highly
|
|
configurable, Nagios replacement. Sensu can be described as a
|
|
"monitoring router", since it connects check scripts across any number
|
|
of systems with handler scripts run on one or more Sensu servers. It
|
|
is compatible with existing Nagios checks and additional checks can be
|
|
written in any language similar to writing Nagios checks. Check
|
|
scripts can send alert data to one or more handlers for flexible
|
|
notifications. Sensu provides the server, client, api and dashboard
|
|
needed to build a complete monitoring system.
