Sensu is an open source monitoring tool for ephemeral infrastructure and distributed applications. It is an agent based monitoring system with built-in auto-discovery, making it very well-suited for cloud environments. Sensu uses service checks to monitor service health and collect telemetry data. It also has a number of well defined APIs for configuration, external data input, and to provide access to Sensu's data. Sensu is extremely extensible and is commonly referred to as "the monitoring router".
To learn more about Sensu, please visit the website and read the documentation.
Sensu Go is a complete rewrite of Sensu in Go, with new capabilities and reduced operational overhead. It eliminates several sources of friction for new and experienced Sensu users.
The original Sensu required external services like Redis or RabbitMQ. Sensu Go can rely on an embedded etcd datastore for persistence, making the product easier to get started with. External etcd services can also be used, in the event that you already have them deployed.
Sensu Go replaces Ruby expressions with JavaScript filter expressions, by embedding a JavaScript interpreter.
Unlike the original Sensu, Sensu Go events are always handled, unless explicitly filtered.
Sensu Go installer packages are available for a number of computing platforms (e.g. Debian/Ubuntu, RHEL/Centos, etc), but the easiest way to get started is with the official Docker image, sensu/sensu.
See the installation documentation to get started.
