• a system configuration collector configured to collect the configuration data;
• a system task monitor configured to collect the management workflow data;
• a service event monitor configured to collect the service failure data;
• a system performance monitor configured to collect the workload data;
• and
• a log aggregator receiving logs from the system configuration collector, the system task monitor, the service event monitor, and the system performance monitor and transmitting the logs over a computer network to the log preprocessor at the first site.

15:

• The method of claim 14, wherein said determine an administrator comprises the system task monitor being configured to:
• create a first map between a user caller session and a client ID;
