Monitoring | Hardware Monitor 4.8

Hardware Monitor is an application to read out all accessible hardware sensors in Macintosh computers. Currently more than 100 different Macintosh hardware sensors and more than 200 hard drive temperature sensors are supported. The program can visualize the history graphs of the readings, display measured values in a large variety of fashions, or announce readings by speech output. It can also store and export readings.

Depending on what sensors are built into your Macintosh system, the following data can be accessed:
Temperarature readings at different locations
Battery data of portable computers
Voltage sensors
Current (amperage) sensors
Fan speed sensors
Sensors for pulse-width controlled fans
Power and load sensors
Ambient light sensors
User-defined artificial sensors to monitor the operating system

New in this version:
Support for Mac OS X 10.3 Panther has been removed. The required minimum OS version is now Mac OS X 10.4 Tiger.
Added a feature to reset different aspects of display preferences for all sensors back to recommended default values. This new feature supersedes the former features to reset sensor display colors, data acquisition settings and customized labels.
Added a feature to display 32/64 bit capabilities of the processor and the current mode of the kernel.
Added a feature to display the unique identifier (UUID) of a computer.
Added a feature to monitor the size of swap space memory which is actually in use.
Added a feature to let the user define individual sets of remotely monitored computers in a network. It is now possible to connect to whole groups of monitored systems in one step.
Added a new driver for monitoring of the internal thermal sensors of Intel processors which is also capable of supporting the 64 bit kernel version of Mac OS X 10.6 Snow Leopard.
On PowerPC hardware, support for S.M.A.R.T. hard drive sensors accessed via SATA interfaces has been enhanced. The application will now accept the temperature sensors of unknown SATA drive models. (This has always been the standard on Intel-based computers.)
The support for hard drive sensors controlled via proprietary drivers of Sonnet and FirmTek has been enhanced.
By user request, a feature to suppress access to S.M.A.R.T. hard drive sensors has been added to the command-line version of the program.
The output channel "Screen Display" will no longer try to keep its screen position if the user changes a multi-monitor configuration while the program is not running. This makes sure the Screen Display cannot become invisible when its target monitor has been removed.
The default number of displayed digits behind the decimal point is now automatically set to zero in cases where it is known that the sensor hardware does not provide more significant digits.
When exporting readings, it is now possible to also use history windows in overlay mode as sources to get combined tables of readings for different physical quantities.
If the application loses the network connection to a remotely monitored computer, related warnings will now be suppressed automatically when a change of the network configuration on the monitoring computer itself is the main reason for the disconnect. This is useful when a mobile computer monitoring a network leaves the WiFi area, for example.
When remote-monitoring multiple computers with repaired logic boards that have invalid or erased hardware serial numbers, the application will now better keep track of the individual identifications of the affected systems.
If the application is set to automatically reconnect to a set of remotely monitored computers on startup, the reconnect will now be performed less aggressively, one by one. This avoids temporary network overload when monitoring a large number of computers.
When quitting the application, shutdown of attached alphanumeric LCD boxes has been enhanced.
The numbering of labels for user-created sensors monitoring battery units will now also start with 1 instead of beginning with 0.
Corrected a problem where the temperature values displayed for the cores of the Intel P7350 processor have been shifted by 15 degrees Celsius.
Corrected a problem where no spaces between values have been displayed in the menu-bar when the display of sensor labels has been switched off.
See complete release notes.

Limitations: During the test phase, only the following restrictions apply:
The program will only display readouts of temperature sensors, not other values like voltage, current, fan speed, etc.
A demo mode panel will appear each time you launch the application. The demonstration window lists in detail which sensors would be available for display if you decided to unlock the program.

Requirements:
OS X 10.4 or later
