    The case for the Windows Agent over ICMP/WMI

    ikomrad

      Is there a good reference that covers the pros and cons of Agent-based monitoring?

       

       

      From the NPM Admin Guide

       

       

       

       

      When host and applications are behind firewall NAT or proxies

       

      Polling node and applications across multiple discrete networks that have overlapping IP address space

       

      Secure encrypted polling over a single port is required

       

      Support for low bandwidth, high latency connections

       

      Polling nodes across domains where no domain trusts have been established

      I'm looking for performance / other attributes , such as

      Pros

      Offload work from polling engines, perhaps reducing the # polling engines needed.

      Easier to manage from a network security ( firewall ) perspective

      ...does it make SAM templates easier to use?  There are few problematic templates such as AppInsight for SQL and Exchange where I'm troubleshoot access and configuration issues. If an agent alleviates them, I'd  install it immediately.

      Cons

      Need to install on each system

      Local CPU/Memory usage

      ...other negatives?

      Basically a sales pitch to convince myself or my superiors that using the WIndows agent has a good return on investment. I encounter cross-domain trust issues, internal firewall rules, software (windows , iptables ) firewall rules, every day. Anything 

       

      I cannot wait until SAM 6.3 introduces the Linux Agent.
