How to Manage your Swift Cluster Using Swift Metrics

Redundancy is built into OpenStack Swift at various levels that I/O operations are capable of riding through failures happening in the cluster. The failures could be disk faults, services stopping or failing, node failures, etc. This presentation talks about building a monitoring system that is constantly receiving and analyzing the Swift metrics and reporting the status of the cluster to the Administrator. We present techniques to baseline a Swift cluster, figure out variances in metrics during failures and ways to report appropriate metrics and errors in a dashboard to the administrator. We will also be covering setup of configuration files in order to enable reporting of StatsD metrics and Swift-Informant metrics in the Swift cluster.
