lm_sensors not working with Zabbix in kernel 2.6

[cybermage]

because /proc/sys/dev/sensors are no more in 2.6 kernel

Based on http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=2028

new path is /sys/bus/i2c

Just FYI

[surftimer]

is there any solution or workaround ?

thank your

a bit crude workaround would be userparameter parsing 'sensors' output

An elegant solution to monitor lm_sensors with zabbix could be compile net-snmp with lmsensors support.

Instructions at http://www.net-snmp.org/docs/README.solaris.html

Lmsensors is under oid 1.3.6.1.4.1.2021.13.16

Temperatures should be divided by 1000 to be correctly presented in zabbix.

Table identifiers might be different on your computer. Take a look at mine:

snmptable localhost -c public -v 1 1.3.6.1.4.1.2021.13.16.2
SNMP table: LM-SENSORS-MIB::lmTempSensorsTable

lmTempSensorsIndex lmTempSensorsDevice lmTempSensorsValue
0 temp1 47000
1 temp2 40000
2 temp3 22000
snmptable localhost -c public -v 1 1.3.6.1.4.1.2021.13.16.3
SNMP table: LM-SENSORS-MIB::lmFanSensorsTable

lmFanSensorsIndex lmFanSensorsDevice lmFanSensorsValue
0 fan1 2205
1 fan2 3901
2 fan3 0
3 fan4 0

snmptable localhost -c public -v 1 1.3.6.1.4.1.2021.13.16.5
SNMP table: LM-SENSORS-MIB::lmMiscSensorsTable

lmMiscSensorsIndex lmMiscSensorsDevice lmMiscSensorsValue
0 in0 1280
1 in1 3295
2 in2 0
3 in3 2959
4 in4 2975
5 in5 0
6 in6 1072
7 in7 2927
8 in8 3232
9 vid 2049
10 alarms 9216000
11 Core 0 47000
12 Core 1 73000
13 Core 2 51000
14 Core 3 73000


Another crude workaround could be extending zabbix agent like this


UserParameter=sensors ,sensors | grep "$1" | head -$2 | tail -1 | awk '{print $"$3"}' | sed 's/[-!@#\$%^&*()°+a-zA-Z]//g'


Example of usage
sensors[fan2,1,2] – Would get the value in the first ocurrance of string fan2, with the value in the second column.

sensors[Core,4,3] – Would get the value in the fourth ocurrance of string "Core", with the value in the third column. Another way to get the same data could be
sensors[“Core 3”,1,3] – Would get the value in the first ocurrance of string "Core 3", with the value in the third column.

sensors[String that identify the sensor, Nth ocurrance of the string that identify the sensor, Column]

Obs: Columns are separated by one or more spaces.

Sensors command output for this example:
