BizTalk MsgBoxViewer is not integrated with BizTalk360: soa-thoughts.blogspot.com/.../biztalk360-new-v25-releasemessage-box.html

Regarding your point "Know what is running in each host", "Consider creating a chart of the artifacts running in each host. This will also help determine if too many items are running in a host or if a host is being underutilized."
BizTalk360 (http://www.biztalk360.com) tackles this exact issue seamlessly by giving a container view for the BizTalk Host, you'll know exactly what's running inside the host. The blog post explains this functionality, please take a look at the topic "4. Host Container View"
Sorry, Saravana I made a typo I definitely want to communicate that BizTalk360 and MBV go hand in hand.
Mandi- Added reference of PAL also whcih i found very usefull for me.
In addition to this, creating an internal WIKI or sharepoint site to keep track of all applications, known error and with solution is also a good tip.. :)
I felt like adding two more points that are very important, keeping a good framework and disaster recovery plan of the environment. Other than that, a very good article, will be useful for many people! Great work Mandi!
