Prometheus is an open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.

prometheus_cd is a Puppet module to automate installation and configuration of prometheus and node exporter. This module supports either managing prometheus or node_exporter or both. You need to set the parameters $manage_prometheusand / or $manage_node_exporterto true ( false by default)

WARNING

Attention: Never use this puppet module on systems which have been previously configured manually. It is impossible to predict how and what would have been configured, hence previous configurations outside the scope of this module may be overwritten! Automated configurations require a test environment to verify that the module suits the purpose intended by the user, as well as tune the parameters, before deploying into live production
