SBS 2008 Monitoring Database Problems

I've run into performance issues on SBS 2008 servers related to the monitoring database. I've noticed this issue as a disk access issue when a server is slow. From Resource Monitor, sorting processes under Disk by the Read Bytes has the SBSMonitoring.mdf file with far more activity that other sources. Typically processor and memory utilization are OK, but not necessarily.

Two separate issues can be the source of the problem:

• SBS Monitoring database is too large and is using large amounts of disk space. If so, check this out: http://blog.korteksolutions.com/the-sbsmonitoring-database-is-nearing-maximum-size-on-sbs-2008/. I used the downloadable new database from this location and it worked great.
• Missing indexes in SBS Monitoring database cause high disk and maybe processor activity. If so, check this out:  http://social.technet.microsoft.com/Forums/en/smallbusinessserver/thread/d195baac-da8b-4387-9079-c55d5e1879b4
