Chapter 14 Monitoring Your Network
Monitoring Load Balancing
Admin Status The specified state of the server, which can be:
• Inservice—Indicates the server is in service.
• Out of Service—Indicates the server is out of service.
• In Service Standby—Indicates the server is a backup server and remains inactive unless the
primary server fails. If the primary server fails, the backup server becomes active and starts
accepting connections.
Operational Status The state of the server, which can be:
• Inservice—Indicates the server is in service.
• Out of Service—Indicates the server is out of service.
• Inservice Standby—Indicates the server is a backup server and remains inactive unless the
primary server fails. If the primary server fails, the backup server becomes active and starts
accepting connections.
• Probe Failed—Indicates that DM did not receive a response to a health probe that it sent to the
server.
VM Indicator that the real server is, or is not, a VMware virtual machine as follows:
• – (dash)—The real server is not a VMware VM.
• Yes—The real server is a VMware VM. To view details about the VM, click Yes. The Virtual
Machine Details pop-up window appears and provides the following information about the VM:
–
Full path—Full path to the VM.
–
DNS Name—DNS name of the VM.
–
IP Address—VM IP address.
–
State—Operating state of the VM (for example, poweredOn).
–
Guest OS—Guest operating system (for example, Red Hat Enterprise Linux 5 (32-bit)).
–
Host—Host IP address.
–
Memory (MB)—Amount of memory.
–
CPU (MHz)—CPU frequency.
–
Triggered Alarms—Number of recorded triggered alarm conditions.
Click OK to close the Virtual Machine Details pop-up window.
Weight Weight assigned to the real server.
Locality Locality also requires that you have the ACE configured for Dynamic Workload Scaling (see the
“Configuring Dynamic Workload Scaling” section on page 6-14).
Possible values for real server locality are as follows:
• N/A—Not available; the ACE cannot determine the real server location (local or remote). A
possible cause for this issue is that Dynamic Workload Scaling is not configured correctly.
• Local—The real server is located in the local network.
• Remote—The real server is located in the remote network. The ACE bursts traffic to this server
when the local real server's CPU and/or memory usage reaches the specified maximum
threshold value.
