Oracle Webcenter Content (UCM) health check Procedure

hi

what is the main consideration for doing health check for the system like UCM ?

when you go to site and needs to check the system ,for me i would do the following checks :

1-check log files to check errors if available .

2-check DB table space size .

3-check server memory resources .

4-check CPU usage .

5-check memory of weblogic server .

i need to know if there is another areas that had to be checked from your experience ,any useful tools also ?
