<H2>DESCRIPTION</H2>
|
|
|
|
sensors-detect is an interactive program that will walk you through the
|
|
process of scanning your system for various hardware monitoring chips,
|
|
or sensors, supported by <A HREF="/cgi-bin/man/man2html?3+libsensors">libsensors</A>(3), or more generally by the lm_sensors
|
|
tool suite.
|
|
<P>
|
|
sensors-detect will look for the following devices, in order:
|
|
<DL COMPACT>
|
|
<DT id="1">•<DD>
|
|
Sensors embedded in CPUs, south bridges and memory controllers.
|
|
<DT id="2">•<DD>
|
|
Sensors embedded in Super I/O chips.
|
|
<DT id="3">•<DD>
|
|
Hardware monitoring chips accessed through ISA I/O ports.
|
|
<DT id="4">•<DD>
|
|
Hardware monitoring chips reachable over the SMBus or more generally
|
|
any I2C bus on your system.
|
|
</DL>
|
|
<P>
|
|
|
|
As the last two detection steps can cause trouble on some systems, they
|
|
are normally not attempted if the second detection step led to the
|
|
discovery of a Super I/O chip with complete hardware monitoring features.
|
|
However, the user is always free to ask for all detection steps if so is
|
|
his/her wish. This can be useful if a given system has more than one
|
|
hardware monitoring chip. Some vendors are known to do this, most notably
|
|
Asus and Tyan.
|
|
<P>

<H2>OPTIONS</H2>
|
|
|
|
<DL COMPACT>
|
|
<DT id="5">--auto<DD>
|
|
Run in automatic, non-interactive mode. Assume default answers to all
|
|
questions. Note that this isn't necessarily safe as the internal logic may
|
|
lead to potentially dangerous probes being attempted. See the WARNING section
|
|
below.

|

|
|
<H2>WARNING</H2>
|
|
|
|
sensors-detect needs to access the hardware for most of the chip detections.
|
|
By definition, it doesn't know which chips are there before it manages to
|
|
identify them. This means that it can access chips in a way these chips do
|
|
not like, causing problems ranging from SMBus lockup to permanent hardware
|
|
damage (a rare case, thankfully.)
|
|
<P>
|
|
The authors made their best to make the detection as safe as possible, and
|
|
it turns out to work just fine in most cases, however it is impossible to
|
|
guarantee that sensors-detect will not lock or kill a specific system. So,
|
|
as a rule of thumb, you should not run sensors-detect on production servers,
|
|
and you should not run sensors-detect if can't afford replacing a random
|
|
part of your system. Also, it is recommended to not force a detection step
|
|
which would have been skipped by default, unless you know what you are doing.
