Measure the heartbeat of your Openstack deployments


Manali Latkar


To introduce Stacktach as a monitoring/debugging/reporting/double entry verification tool for Openstack deployments through a live demo.


Nearly all OpenStack components are capable of generating notifications when significant events occur. Notifications are messages placed on the OpenStack queue (generally RabbitMQ) for consumption by downstream systems.

StackTach has a worker that is configured to read these notifications and store them in a database. From there, StackTach reviews the stream of notifications to glean
usage information and assemble it in an easy-to-query fashion. It also verifies the usage information that is used for billing to eliminate over/underbilling.
Users can inquire on instances, requests, servers, etc using the browser interface or command line tool (Stacky).
Stacktach also creates audit reports for everyday according to the usage data which help in discovering a lot of bugs/irregularities in the deployments.
It is an open source project.


Beginner knowledge about python and interested in monitoring OpenStack deployments.
