Has anyone used this feature for network management, if so what is you opinion f the usefulness, is it worth the time learning how to set it up? I am interested in using this feature to help determine if user complaints are application issues or true network issues.
I'd say it was invaluable if you want to have any idea of what your baseline network operations look like - one of the biggest issues with troubleshooting is that you often don't know what "normal" looks like - and IP SLA gives you this info. (IP SLA used to be called SAA, and before that it was called RTR)
Although I've only used IPM (there are also plenty of 3rd party products) it can be invaluable, for example if you set it up to monitor how long a web page takes to load you can get network latency, dns lookups and the actual page download times graphed over a period of time - if things run slow you can see at a glance which component is giving problems.
IPM is also quite simple - there isn't much of a learning curve and you can have it up and running in a couple of hours.
Regarding troubleshooting, here's a quote from the FAQ:
Q. How can Cisco IOS IP SLAs troubleshoot the network?
A. Cisco IOS IP SLAs can be configured with thresholds. When the performance level crosses the thresholds, Cisco IOS IP SLAs can generate SNMP traps to notify applications. This helps to detect a potential problem. Additionally, a network administrator can obtain hop-by-hop performance information using Cisco IOS IP SLAs ICMP Path Echo and Path Jitter operations. This isolates any performance bottleneck.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
