I have been working in IT since 2001 for companies such as Computacenter and Getronics. I started out as a first line support analyst supporting heterogeneous networks but rapidly worked my way up the ranks expanding my knowledge as I went to include areas such as system builds, deployments, networking, and security to name a few.In 2008 I decided to concentrate on the monitoring and management of large enterprise networks using Microsoft's System Center Operations Manager (OpsMgr) 2007 of which I have extensive knowledge. As testament to this the Windows Management User Group (WMUG), invited me to join their ranks as a Community Leader where I have been invaluable in helping to bolster the OpsMgr skills to the benefit of the group and it's members.I have now moved into an OpsMgr 2007 consultancy role to do what I like most - working with OpsMgr and sharing my knowledge and experiences with the community.
Within SC2012 Operations Manager it is now possible to use sudo elevation for agent push, upgrades etc, and for RunAs accounts. With this addition though, you will probably get more questions for the your UNIX/Linux admins about configuring the accounts to perform monitoring and agent tasks with the minimum amount of permissions. Well, MS already has a TechNet Wiki article available to provide this information, just follow the link below.
If you perform X-Plat monitoring, I would recommend looking at this article as contains samples for all the supported platforms.
