Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

The outage that beset Amazon.com's retail home page lasted longer than some observers first believed. Reports have put the outage variously at 15 minutes, 25 minutes or "just under a half an hour," as Forbes reported soon after the incident.

But in fact, it lasted 49 minutes, according to a monitoring service at Compuware, the owner of CloudSleuth cloud service monitoring and the Gomez Web application performance monitoring system, now part of the Compuware APM service. Despite inquiries, Amazon.com spokesmen have remained silent on the cause of the incident Monday and its duration. News reports have been sketchy.

Compuware staff double checked the Monday incident that saw Amazon.com home page going dark with customers getting an "Oops" message around noon Pacific time and not becoming available again until 49 minutes later. Only North American users appear to have lost service. Europe and other parts of the world were unaffected, contrary to an earlier report.
