Systems administration and monitoring In an active server farm, machines can be added and removed, or brought offline for maintenance. Load-balancing devices aid in this process, redirecting traffic destined for specified IP addresses and protocols as necessary. However, the administration interfaces of the ma-chines can be quite different. All of the devices support large numbers of servers, which should be sufficient for any Web site. Local Director has a command-driven interface for maintenance and monitoring and can be administered via telnet.
Configuration is straightforward, with just a few commands required to get online.
Being Unix-based, it can be monitored using standard Unix tools. The virtual hosts are the names and IP addresses published to the Internet, from which the load-balancing devices redirect traffic to one or more real devices that service the requests. Web Server Director has the easiest and most intuitive systems administration interface and load-monitoring utilities. You can manage the device remotely using a graphical interface on a PC or via a console session. Web Server Director is accessed via a graphical client.
