Cloudera Manager | Log Management, Event Management and Alerting Demo Video by Jon Zuanich
From the post:
In this demo, Henry Robinson, a software engineer at Cloudera, discusses the Log Management, Event Management and Alerting features in Cloudera Manager that help make sense out of all the discrete events that take place across the Hadoop cluster. He demonstrates how to search the logs valuable information, note important events that pertain to system health and create alerts to warn you when things go wrong.
As a once upon a time sysadmin, I know making a system transparent for users is the result of a lot of unseen work.
I think I have less than 50 (fifty) nodes, ;-), so I will have to take this for a spin. I need to find some cheap commodity boxes so I can set up a 3 or 4 node test bed. I can try in on a single node system just to get my feet wet.
If you are using Cloudera Manager or try it out, point me to a blog with your comments.
