This document summarizes Brad Klein's presentation on Time Warner Cable's use of the Monasca monitoring platform. It includes an overview of Monasca functionality, a description of TWC's private OpenStack deployment that Monasca monitors, and demonstrations of Monasca's infrastructure monitoring dashboards and the ability to push custom metrics and view graphs. The presentation also covers decisions around metrics collection, database selection, and upcoming Monasca features.

 Alerting
 Email
 PagerDuty
 Webhooks -- POST
 Built in metrics
 Basics for free (be careful!)
 Custom Metrics
 You choose what to push

7. Why Not Ceilometer?

9. Architecture

10. Our deployment

11. Deployment success

12. Deployment success (cont.)
# monasca_stack.sh --help
Usage: --help {status|start|stop|restart|tail-logs|tail-metrics|local-lag|
mirror-lag}

 (demo metric flow)

13. A word to the wise
Metrics per second:
Before: 5,300/sec
After: 3,000/sec
(~2 million data points/day saved)

14. What’s Coming
 Monasca:
 Big Tent Push
 Heat Integration
 Ceilometer Integration
 https://github.com/stackforge/monasca-ceilometer
 TWC:
 Split database from monasca stack
 MaaS Beta
 Chargeback (vCPU hours)
 Savable dashboards?
 Per project data retention policy

15. Deployment Decisions
 What metrics do you care about?
 Auto-setup of plugins vs explicit
 Backend database?
 InfluxDB
 Vertica ($)
 Cassandra
 Dedicated DB nodes?
