Error



2009/01/08 01:22:37 VCS CRITICAL V-16-1-50086 CPU usage on is 100%

Environment



Linux systems with VCS 5.0MP3


Cause



The HostMonitor Agent in VCS 50MP3, uses a value of type "unsigned long long" instead of "unsigned long" for CPU usage counters on Linux.
This causes the agent to report CPU usage incorrectly, as 100% every two hours in /var/log/messages. The actual system CPU usage woule be very low.
