DFM/Operations Manager/OnCommand(all different evolutions of the NetApp monitoring and managment system) allow for monitoring of snapmirrors, including alerting via pager or email.
Otherwise you will need to script a system to check the snapmirrors or the snapmirror log file for failures.
I know of a product called Aptare that can monitor and report as a third party solution as well, but that is the only one I know of as we use DFM. It looked pretty in depth, but I left the company that was looking at it before a decision was made to use it.
Another 3rd party SaaS product that does SnapMirror (and anything else you can imagine on a NetApp - vfiler, volume latency, PAM utilization - or anything else (vmware, mysql, etc)) is LogicMonitor.
Nicely automated, but powerful and tunable.
