SYNOPSIS

healthd [-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 monitoring 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
.Mn healthd 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 available 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 different 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 format 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 kernel. NOTE: This is only for 4.x versions of FreeBSD. controller smbus0 controller iicbus0 controller iicbb0 controller intpm0 device smb0 at smbus?

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.
