Monitoring Outdated VMware 3.x
Being a leading provider of virtualization technologies, VMware provides a set of products including desktop and enterprise (server) solutions. Iotellect Network Manager provides control and monitoring for VMware ESX/ESXi servers and Guest Virtual Machines (Guest VMs).
For the purposes of discussion we decompose virtual systems monitoring into several levels: server level, virtual machine level, and operating system level. In the context of this classification Iotellect Network Manager provides monitoring at all the levels with both generic and VMware-specific tools. Namely, at the server level, VMware server can be treated as a standard Linux machine and therefore can be monitored with "universal" monitoring tools (see Device Availability Monitoring, Performance Monitoring, Applications and Services Monitoring). Similarly at operating system level, operating system that runs inside a Guest VM acts like any other operating system, and therefore can be monitored using the same approach.
VMware-specific tools are primarily needed for monitoring at the level of particular virtual machines, as this is the place where all the "magic" actually happens. Iotellect Network Manager VMware virtual machine monitoring toolset allows to monitor particular virtual machines running on the specified VMware server. It includes VMware Information Widget along with a set of alerts and charts. The toolset can be customized if necessary, or extended by creating new tools using the existing ones as templates and/or examples.
Iotellect Network Manager monitors virtual machines running on VMware servers via SNMP, using vmTable, cpuTable, memTable, vmwHBATable, and vmwNetTable variables. These variables are automatically configured for periodic polling (to provide live refreshing of the values), and historical values storage (for statistical analysis). The polling settings can be adjusted for specific tasks using Device Settings Synchronization Options. Refer to VMware documentation for more information on enabling SNMP on VMware servers.
