About Cloud monitoring software applications :
Cloud services are extremely beneficial for any business but due to increased data security threats, these services are often not used by the managers. A simple solution is cloud monitoring system to manage cloud resources and software infrastructure. Cloud monitoring system helps monitor the performance and capacity requirements. Performance management includes supervision of apps to ensure an optimal performance and availability.
Hyperic cloud monitoring tool :
Hyperic can automatically discover, manage and monitor IT and network resources on both private and public clouds. It monitors system resources such as operating systems, hardware, databases, middle-ware and applications. It monitors network services and host resources. It also supports remote monitoring, enables auto-discovery of system resources, identifies problems and performs root cause analysis.
Ganglia cloud monitoring tool :
This tool monitors high performance computing systems like public clouds, private clouds, clusters and grids. Ganglia contains the below mentioned features.
Gmond, a multi-thread daemon, runs on each mode to monitor changes in the host state. It monitors the states of Ganglia nodes via an installation based uni-cast or multi cast channel and responds to requests. Ganglia Meta Daemon polls at regular intervals. It collects the data sources, parses the XML, saves all metrics to round-robin databases and exports the aggregated XML. The Ganglia web front-end is written in PHP and it uses graphs generated by GMETAD. It provides accumulated information like information about the CPU utilization in the past day, week, month or year. Multi cast mode is the default mode when you install Ganglia. Public cloud environments like Amazon's AWS EC2 do not support multicast. Thus, unicast mode is the only set-up option available. Eucalyptus is an open-source product for building AWS compatible private clouds. The open-source version does not provide built-in monitoring. To enable Eucalyptus-specific monitoring on a predefined number of hosts, the Eucalyptus source package includes a script that can be used with third party tools such as Ganglia.
Nagios cloud monitoring tool :
This tool monitors network services and host resources. Nagios core is an open source, infrastructure monitoring system that helps organizations diagnose IT infrastructure problems before they affect business processes. Nagios can monitor virtual servers and operating systems in both physical and virtual environments. With Nagios, it is easy to identify any issues in cloud environment and check application availability.
This tool offers multiple benefits such as high availability, fault tolerance and data availability. Nagios monitors public cloud services such as Amazon EC2 (Elastic Compute Cloud) and Amazon S3. The open source versions of Eucalyptus do not provide built-in monitoring but this can be achieved with Nagios by using scripts in the extras directory along with third party tools. Nagios allows users to write plugins and run them on remote servers.
