| /* lmSensors.c |
| * |
| * Sections of this code were derived from the published API's of |
| * some Sun products. Hence, portions of the code may be copyright |
| * Sun Microsystems. |
| * |
| * Additional code provided by Mike Fisher and Thomas E. Lackley |
| * |
| * This component allows net-snmp to report sensor information. |
| * |
| * In order to use it, the ./configure invocation must include... |
| * |
| * --with-mib-modules="ucd-snmp/lmSensors" |
| * |
| * It uses one of three different methodologies. Some platforms make |
| * use of an lm_sensors driver to access the information on the |
| * health monitoring hardware, such as the LM75 and LM78 chips. |
| * |
| * For further information see http://secure.netroedge.com/~lm78/ |
| * |
| * The Solaris platform uses the other two methodologies. Earlier |
| * platforms such as the Enterprise 450 use kstat to report sensor |
| * information. Later platforms, such as the V880 use the picld |
| * daemon to control system resources and report sensor information. |
| * Picld is supported only on Solaris 2.8 and later. |
| * |
| * Both these methodologies are implemented in a "read only" manner. |
| * You cannot use this code to change anything eg. fan speeds. |
| * |
| * The lmSensors component delivers the information documented in the |
| * LM-SENSORS-MIB. The information is divided up as follows: |
| * |
| * -temperatures (in thousandsths of a Celsius degree) |
| * -fans (rpm's) |
| * -voltages (in milliVolts) |
| * -other (switches, LEDs and i2c's (things that use the i2c bus)) |
| * NOTE: This version does not support gpio's. Still on the learning curve. |
| * |
| * Because the MIB only allows output of the datatype Gauge32 this |
| * limits the amount of meaningful information that can be delivered |
| * from "other" sensors. Hence, the code does a certain amount of |
| * translating. See the source for individual sensor types. |
| * |
| * If an "other" sensor delivers a value 99, it means that it |
| * is delivering a "status" that the code does not account for. |
| * If you discover one of these, please pass it on and I'll |
| * put it in. |
| * |
| * It was recently discovered that the sensors code had not be following |
| * the MIB for some sensors. The MIB required reporting some items |
| * in mV and mC. These changes have been noted in the source. |
| * |
| * To see debugging messages, run the daemon as follows: |
| * |
| * /usr/local/sbin/snmpd -f -L -Ducd-snmp/lmSensors |
| * (change path to wherever you installed it) |
| * |
| * or using gdb: |
| * |
| * gdb snmpd |
| * run -f -L -Ducd-snmp/lmSensors |
| * |
| * The component can record up to 256 instances of each type. |
| * |
| * The following should always be included first before anything else |
