Overview

This plugin provides a check for system uptime for Sensu Go. The sensu-go-uptime-check check takes the flags -w (warning) and -c (critical) and a time duration after each flag (e.g. 24h). The time values can be represented in seconds (s), minutes (m), or hours (h). The plugin uses a default warning value of 72h and a default critical value of 168h (1 week).
