This presentation describes the role that standard server performance metrics play in increasing the scalability and reducing the operational complexity of performance monitoring in large data centers.
The presentation uses popular performance monitoring tools: Nagios, Ganglia, Collectd, Cacti and Munin to demonstrate the complexity of managing each application's agents on multiple platforms and servers. The tools are then used demonstrate that a core set of metrics is widely recognized and broadly supported. The presentation goes on to show how an agent exporting these standard metrics allows performance monitoring tools to share data, eliminating the need for wasteful duplication. Finally, by including server performance metrics in the sFlow standard, server performance monitoring becomes part of an integrated solution that includes networking, servers and applications.
