1.1 Outline
1.1.1 Outline of HEW
HarnessEye/web (hereafter referred to as HEW) is the web-based software used in managing
the operation of Toshiba IA servers. By installing HEW, it is possible to see the state of the
monitored server in a Internet Explorer window. Also, hardware information specific to Toshiba
Intel Architecture servers can be monitored for fault detection.
HEW modules
HEW is roughly divided into the following three modules:
Management Console
Management Proxy
Agent
As a configuration example, each module is installed on another machines (a server, a note
PC, etc.) as shown in <Figure 1>. It is also possible to install all modules on one
machine as shown in <Figure 2>.
The HTTP protocol is used for communication between the Management Console and the
Management Proxy. The SNMP protocol is used for communication between the
Management Proxy and the Agent.
In-band means network communication when the OS is running on the Agent machine (i. e.
on a machine, where an HEW Agent is installed).
Out-of-band means network communication using a special function, when the operating
system of an Agent machine is stopped.
