In this talk, we will discuss the past and present
history and the design principles of the OpenBSD
hardware sensors framework. Sensors framework
provides a unified interface for storing, registering
and accessing information about hardware monitoring
sensors. Sensor types include, but are not limited
to, temperature, voltage, fan RPM, time offset and
logical drive status. The framework spans
sensor_attach(9), sysctl(3), sysctl(8), sensorsd(8),
ntpd(8), snmpd(8) and more than 67 drivers, ranging
from I2C temperature sensors and Super I/O hardware
monitors to IPMI, RAID and SCSI enclosures. Several
third-party tools are also available, for example,
a plug-in for Nagios and ports/sysutils/symon.
Originally based on some ideas from NetBSD, the
framework has sustained many improvements in OpenBSD,
and was ported and committed to FreeBSD and DragonFly
BSD.
Constantine A. Murenin is an MMath graduate student
at the David R. Cheriton School of Computer Science
at the University of Waterloo (CA). Prior to his
graduate appointment, Constantine attended and
subsequently graduated from East Carolina University
(US) and De Montfort University (UK), receiving two
bachelor degrees in computer science, with honors
and honours respectively. A FreeBSD Google Summer
of Code 2007 Student, OpenBSD Committer and Mozilla
Contributor, Constantine's interests range from
standards compliance and usability at all levels,
to quiet computing and hardware monitoring.
