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 + */ + +#include <net-snmp/net-snmp-config.h> +#include <net-snmp/net-snmp-features.h> +#include <net-snmp/net-snmp-includes.h> +#include <net-snmp/agent/net-snmp-agent-includes.h> + +/* + * minimal include directives + */ + +#include "util_funcs/header_simple_table.h" +#include <time.h> + +netsnmp_feature_require(table_container) + + +/* + * Load required drivers and libraries. + */ + +#ifdef solaris2 + #include <kstat.h> + #ifdef HAVE_PICL_H + #include <picl.h> /* accesses the picld daemon */ + #else + /* the following should be sufficient for any Sun-based sensors */ + #include </usr/platform/sun4u/include/sys/envctrl.h> + #endif +#else + #include <sensors/sensors.h> + #define CONFIG_FILE_NAME "/etc/sensors.conf" +#endif + +#include "lmSensors.h" + +#define TEMP_TYPE (0) +#define FAN_TYPE (1) +#define VOLT_TYPE (2) +#define MISC_TYPE (3) +#define N_TYPES (4) + +#ifdef solaris2 + #define MAX_NAME (256) + #define MAX_SENSORS (256) /* there's a lot of sensors on a v880 */ +#else + #define MAX_NAME (64) + #define DEFAULT_SENSORS (256) +#endif + + +/* + * lmSensors_variables_oid: + * this is the top level oid that we want to register under.
