Reconnoiter's goal is to better the world of monitoring by marrying fault detection and trending together. Through ease of configuration and ongoing maintenance, Reconnoiter encourages monitoring important technical metrics along side critical business metrics to improve awareness and ultimately accountability.


  • Web console to provide a view into the world.
  • Core database, holds metrics and business logic for determining faults, fault notification and escalation procedures
  • Strategy daemon to collect information from Scout nodes
  • Scout nodes that perform checks. Scout nodes run extremely efficiently -- tens of thousands of services monitored per scout.

A picture is worth a thousand words.

Development at this point is pretty rapid. As such, decisions are made that might cause what we call a "flag-day". A flag-day is when an upgrade through a specific version will prevent some functionality between that version and an older version. Commits that do this (like a change in protocol) will be marked as "flag-day" commits and note the system components that must be lock-step upgraded. Review flag-day commits.

Specific (significant) upgrade notes.

Installation can be a bit tricky, it might help to look at this step-by-step guide to installing on Debian.
