a graceful shutdown (if the NetServer SNMP agent software is installed), a
reboot, or a complete power cycle. An administrator can also remotely power off
the server if, for example, there has been a critical hardware failure. If text
remote control is enabled during server reboot, the actual bootup screens can be
viewed at a remote site.
Remote configuration. An administrator at a remote client can reconfigure HP
TopTools Remote Control and change features such as notification actions. An
administrator can also change user and administrator permissions without having
to be at the server.
Management and Security
Remote management security. An administrator can assign access for up to 16
users, providing them with individual login identification, encrypted password
and privileges. User privileges define the right to perform a specific action (for
example, powering down the server). Use management can thus be set up by an
administrator at a remote site without compromising network security. The
TopTools Remote Control login procedure is protected so that the password is not
sent across the LAN.
Dialback option. If a user is using modem communications, the HP TopTools
Remote Control card may be configured for dialback. Dialback authorization
requires the user’s ID. If the ID matches an entry in the user database, HP
TopTools Remote Control initiates an automatic call-back via the external
modem connected to the card.
Server Performance Monitoring
HP TopTools Remote Control monitors I/O performance by gathering statistics
on PCI bus usage. The following server operations and conditions are monitored:
• Bus utilization. The ratio of use to total PCI cycles. This is an indicator of
the server’s I/O load.
• Bus efficiency. The ratio of the amount of data transferred (throughput)
to total PCI data transfer capacity. This is an indicator of how effectively
the server’s PCI devices are using the bus.
HP TopTools Remote Control monitors the following conditions:
Environment monitoring. HP TopTools Remote Control displays sensor values
for each sensor in the server. These include sensors for voltages, temperatures,
and fan speed.
Logging of server events. HP TopTools Remote Control displays the server’s
System Event Log (SEL) information for viewing by an administrator at a remote
