SCOM Cross platform monitoring for Linux

This procedure is to describe the steps for monitoring Linux system From Operation Manager 2007 R2. Some items which you want to monitor may not show up in the OM console. 
We had inquiries about this with Microsoft. they gave an advice that we should build our own MP(Management Pack).


1. Install MPs
   download & install SCOM Cross Plaform ManagementPack


2. Install Cumulative Update
   - CU 3 (KB 2551525) 
   - CU 4 (KB 2449679)


3. SCOM started data collection for linux five hours later after step 2, 
    According to Microsoft, Linux discovery can take long time (up to 1 day) 


4. We can get performance data from SCOM database. but, some data doesn't provide from SCOM Cross Platform management pack.
Here, we couldn't get network usage(%) information. 


In this case, we should make user-defined MP and apply to SCOM conole.
