So I'm trying to get net-snmp to return lm_sensors data so I can monitor the temperature and fan speed of my PC. But currently it won't return any data:
$ snmpwalk -v2c -c public localhost lmSensors LM-SENSORS-MIB::lmSensors = No more variables left in this MIB View (It is past the end of the MIB tree) Note that it's not saying that it does not know about lmSensors so it seems like it found the MIB alright. Also sensors does return what seems like suitable data to me: $ sensors coretemp-isa-0000 Adapter: ISA adapter Core 0: +50.0°C (high = +74.0°C, crit = +100.0°C) Core 1: +50.0°C (high = +74.0°C, crit = +100.0°C) Core 2: +46.0°C (high = +74.0°C, crit = +100.0°C) Core 3: +50.0°C (high = +74.0°C, crit = +100.0°C) it8718-isa-0290 Adapter: ISA adapter Vcore: +1.12 V (min = +0.00 V, max = +4.08 V) Vram: +1.87 V (min = +0.00 V, max = +4.08 V) +3.3V: +3.15 V (min = +0.00 V, max = +4.08 V) +5V: +4.70 V (min = +0.00 V, max = +6.85 V) +12V: +12.16 V (min = +0.00 V, max = +16.32 V) Vbat: +3.26 V CPU Fan: 1207 RPM (min = 10 RPM) F/Low Fan: 0 RPM (min = 10 RPM) F/High Fan: 1300 RPM (min = 0 RPM) NBr Temp: +45.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor CPU Temp: +34.0°C (low = +127.0°C, high = +80.0°C) sensor = thermal diode intrusion0: OK In particular notice the 'V' and 'Temp' labels which I believe should allow net-snmp to recognize these as voltages and temperaturs. Here's what I did so far: * I'm running Testing so I installed: snmp 5.4.3~dfsg-3 snmpd 5.4.3~dfsg-3 snmp-mibs-downloader 1.1 libsnmp15 5.4.3~dfsg-3 lm-sensors 1:3.3.3-1 * Commented out the 'export MIBS=' line in /etc/default/snmpd. I also tried pointing it to specific MIB files to no avail. * Commented out the 'mibs :' line in /etc/snmp/snmp.conf. * Here's a summary of /etc/snmp/snmpd.conf: agentAddress udp:127.0.0.1:161 view systemonly included .1.3.6.1.2.1.1 view systemonly included .1.3.6.1.2.1.25.1 rocommunity public default -V systemonly rouser authOnlyUser sysLocation Sitting on the Dock of the Bay sysContact Francois Gouget <fgou...@free.fr> sysServices 72 proc mountd proc ntalkd 4 proc sendmail 10 1 disk / 10000 disk /var 5% includeAllDisks 10% load 12 10 5 trapsink localhost public iquerySecName internalUser rouser internalUser defaultMonitors yes linkUpDownNotifications yes master agentx * I found a comment that claims that net-snmp 5.5 or greater is required to get integration with lm-sensors. Yet I believe that functionality was present long ago and could not find confirmation. Also net-snmp 5.5 is not available in Testing. http://www.net-snmp.org/wiki/index.php/Net-SNMP_and_lm-sensors_on_Ubuntu_10.04 So has anyone else been able to get net-snmp and lm-sensors to play nice together.
