Organizations invested in Microsoft System Center Ops Mgr 2007 or Microsoft Operations Manager (MOM) 2005 and already using (or planning to deploy) VMware vSphere require an integrated solution providing monitoring and data consistency in their Ops Mgr Enterprise Management System (EMS).
An important part of the production environment, vSphere requires the same level of monitoring as the Microsoft Windows infrastructure. At first glance various methods exist for monitoring servers in the virtual infrastructure – however it is crucial to choose the correct technology solution. Here are some common technical approaches and their pros and cons:
An Ops Mgr agent installed inside a Guest Operating System (OS) running in a Virtual Machine (VM) does not provide correct VM resource monitoring data and does not monitor the additional aspects of vSphere virtualization.
Solutions based on installing a Linux-style agent in the ESX Host Console Operating System (COS), or on using SSH, SNMP or Syslog present problems including:
An incomplete picture of system health
Impact on hypervisor stability
Lack of long-term supportability
No assurance of future compatibility with VMware innovations
Most solutions for VMware vSphere monitoring provide limited out of the box Ops Mgr integration, requiring additional consoles, databases, and configuration utilities in order to work. This contributes to “console sprawl” and results in “swivel chair management” using multiple management consoles.
The nworks Management Pack avoids the problems mentioned above as it uses native VMware APIs to gather performance, event and configuration data from VMware Infrastructure and vSphere.”
