HEALTHD(8) BSD System Manager's Manual HEALTHD(8)NAMEhealthd — Motherboard “health” monitor
SYNOPSIShealthd [-BLVdl] [-f configfile] [-1|2] [-4] [-6] [-c count] [-t count]
[-P port] [delay]
DESCRIPTION
This program provides a facility to read values from the hardware moni‐
toring circuitry on modern motherboards and report when the results are
outside of acceptable bounds set in a configuration file.
Healthd normally runs in the background and reports error conditions via
the syslogd(8) facility. If the “-d” flag is specified, healthd with not
become a daemon, but will stay in the foreground and display the values
for all parameters. This maybe useful to characterize the normal range
for a motherboard.
Currently will try it to determine the chipset type, if not is detected
it will default to W83782D, unless over-ridden by the “-1” flag. It can
detect W83781D, W83782D, W83783S, LM78, LM79 and the AS99127F. The
AS99127F is SMB only, it has no ISA connection.
OPTIONS
The following command line options are available.
-I Use the ISA bus to access the hardware monitor (Default).
-S Use the SMB to access the hardware monitor. This my require
additional lines to be added to the kernel and the kernel to
be rebuilt.
-B Use the Vbat input on the W83782D type chips for the CPU core
voltage of the second CPU.
-d Do not detach and become a daemon. Remain running in the
foreground and display all readings in debug mode.
-l Only bind the the loopback interfaces, instead of all avail‐
able network interfaces.
-f config_file
File name of the configuration file to be used.
-1 Specify the Winbond 83781D, or equivalent, monitor chip
(default).
-2 Specify the Winbond 83782D, or equivalent, monitor chip.
-4 Don't accept connections on IPv4 addresses.
-6 Don't accept connections on IPv6 addresses. This is only
available if the systems supports IPv6. The default is IPv4
and IPv6.
-P port Use a different port then the default 1281. This is a dif‐
ferent port than previous versions. The older versions used
9669, however 1281 is the official port number.
-c count Repeat the display count times, then exit. This implies the
-d flag.
-t count Repeat the display count times. This is very similar to -c,
except the output is a single, tab delimited line. This for‐
mat is more useful to be read by another program. This
implies the -d flag.
-L Local Only mode. Don't open any network listening sockets to
be used by the healthdc program.
-V Display the current version and exit.
<delay> The number of seconds between readings of the values. The
default is 5 seconds.
USAGE
To use the SMB interface the following lines must be added to the kernel.
And the kernel will need to be rebuilt. The ASUS AS99127F chip does not
have an ISA interface and therefore must have SMB capability in the ker‐
nel. NOTE: This is only for 4.x versions of FreeBSD.

Healthd also monitors TCP port 1281 for information requests from
healthdc. If the system has libwrap installed then it will be used to
control access to the healthd daemon.
NOTES
The following signal have the specified effect when sent to the daemon
process using the kill(1) command:
SIGHUP Causes daemon to read healthd.conf or the file specified on the
commnd line with the -f option. The counts of values that were
out of bounds are also reset.
Configuration File
This file specifies which parameters are active, what they are and their
acceptable range. There are 13 different objects that are monitored.
Three temperatures, three fan speeds and seven voltages. Each object has
four configuration items: active, label, min and max.
