Application research of Hadoop resource monitoring system based on Ganglia and Nagios

As an open source software platform, Hadoop has been applied widely. Aim at the need of Hadoop resource monitoring, this paper introduces Hadoop and two distributed monitoring systems, which are Ganglia and Nagios. We design a resource monitoring system of Hadoop, which can monitor Hadoop comprehensively, and provide real-time monitoring, warning messages and reports. It makes use of the advantages of Ganglia and Nagios, and resolves the problem that Ganglia can´t store data permanently. Finally, an effective solution is provided for resource monitoring of Hadoop.
