Appendix A Network Ports and Protocols
 System Monitor - Performance Monitoring Services
System Monitor - Performance Monitoring Services notifies the policy control
processing of SigmaSystemCenter when statistics on CPU load factor of a
managed machine, a status of utilization, such as disk utilization, or statistics
information of multiple machines in a group exceeds the threshold value.
In addition, System Monitor - Performance Monitoring Services executes high or
low load alert monitoring of virtual machine servers that triggers the actions of the
VM Optimized Placement.
 Monitoring through VMware vCenter Server
SigmaSystemCenter executes the following monitoring through vCenter Server.
• Connection check of a virtual machine server (VMware)
• CPU usage rate of a virtual machine server (VMware)
• Memory usage rate of a virtual machine server (VMware)
• Heartbeat status of a virtual machine (VMware)
• CPU usage rate of a virtual machine (VMware)
• Memory usage rate of a virtual machine (VMware)
• Power status of a virtual machine (VMware)
• Datastore usage rate
• Allocation rate of disk on a datastore
• Status of a datastore connection
• Status of a network connection
When a failure occurs, an alert is generated in vCenter Server. If an alert related to
the above is generated, SigmaSystemCenter notifies it of its policy control
processing.
 Monitoring VMware ESXi
If a managed machine is VMware ESXi, SigmaSystemCenter monitors the
machine directly by connecting remotely to monitor its running status.
To monitor the existence of a machine, SigmaSystemCenter checks the
connection from a management server to VMware ESXi. If the connection is
disconnected, the component notifies the policy control processing of
SigmaSystemCenter of Machine inaccessible error event and if the connection
recovers, SigmaSystemCenter notifies its policy control processing of a Machine
inaccessible error recovery event. In addition, SigmaSystemCenter checks the
disk access status periodically and if the check fails, SigmaSystemCenter notifies
its policy control processing of a Hard disk failure
event.
 Optimized Placement function
Optimized Placement provides the load balancing function. When the load
balancing function determines that high load status cannot be resolved even if all
virtual machine servers in a group are used, it notifies the policy control processing
of SigmaSystemCenter of Scaleout Recommendation event.
