Canary

Monitoring Service for Openstack Taskflow's Jobboards

How does it work?

Task-ception

Taskflow is used to monitor other job-boards, and post to cassandra with its outputs.

Console Scripts

canary-producer

Canary's own producer process that posts jobs to Canary's jobboard

canary-worker

Canary's conductor which pulls jobs off Canary's jobboard, to query paths submitted to it (using Taskflow) and post to cassandra with a timestamp

canary-server

Canary's WSGI server that serves job counts and corresponding jobs, over the period of last x seconds (which is set as interval under canary.conf)
