DevConf 2017

Previously to monitor GlusterFS, applications had to run the cluster/volume status commands in periodic intervals. Let us imagine a Gluster monitoring system which displays a list of volumes and its state, to show the real-time status, monitoring app need to query the Gluster in regular interval to check volume status, new volumes, etc. Assume if the polling interval is 5 seconds then monitoring app has to run gluster volume info command ~17000 times a day!

With Gluster 3.9 release, Events APIs are available which can be consumed by registering applications as Webhooks. A monitoring application can get real-time status of Cluster without polling or with minimal polling.

In this talk, we will learn about Events APIs and how it can be used for monitoring GlusterFS
