I am having the same problem with negative numbers.
I cannot get the voltage or temperature readings to work.
I get these errors.
Running data query
Unkown type = ""
any ideas?
Net-SNMP lm_sensors temperature, fan speed, voltage monitor
Moderators: Developers, Moderators
Well I got that error to go away, for some reason the values for data_input_id in the snmp_query table were completely wrong.
I still can't get anything to happen with the temperature or voltage readings.
The indexing queries work ok but the graphs don't do anything and it looks like something isn;t getting resolved as when I create a graph with these templates I get this message.
Created Graph - server1 - Temperature - |query_templmsensorsdevice|
Any ideas anyone?

I tried to read the hd temps, following the example in the post here but .54 is not available. lm_sensors is compiled in as i get loads of other stuff, just not the hd temps.
snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.2021.54
UCD-SNMP-MIB::ucdavis.54 = No Such Object available on this agent at this OID
snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.2021.54
UCD-SNMP-MIB::ucdavis.54 = No Such Object available on this agent at this OID
Is there any way to get an export of these scripts for 0.8.6c? I have an older version of cacti that wont import these templates due to hash errors. The cacti version that I am using is packaged with debian stable/sarge. Other than that I have SNMP and lm_sensors configured and ready if I could just get at these templates. 
Thanks.
Thanks.
The problem is that GUAGE types can only be positive. The CDEF below works by subtracting the current value from 4294967295 (the maximum 32-bit value), and then multiplying the result by -.001sf_alpha wrote:I had problems with negative value. I have try 64bit 2's complement cannot solve this and it return wrong value. I don't know this is rrdtool bugs or cacti
Code: Select all

Error Compiling
I am running CentOS 4. When I download the latest NetSNMP source and try to compile I get the following error...
configure: error: asked to use lm_sensors but I couldn't find -lsensors
First I was getting an error "can't find sensors/sensors.h" so I copied the /usr/include/linux/sensors.h to a new folder named /usr/include/sensors. What do I need to do so -lsensors can be found?

Re: Error Compiling
I figured my own problem out. Turns out lm_sensors-devel was not installed. I didn't realize it was missing because yum didn't list it at all (as installed or available).The00Dustin wrote:I am running CentOS 4.

But I'm working on 64bit systems and it must be subtract by a VERY BIG (2^64) value with different from 32bits system (2^32).ehall wrote:The problem is that GUAGE types can only be positive.

That produces the difference value, and then makes it negative with the right decimal scope.Code: Select all

Have to split 2 version of CDEF for this, 32bit and 64bit ?!?
Problem to graph CPT Temp
Hi,
I use Cacti since a few month, and appreciate it.
I recently tried tu use Cacti to graph CPU temp, but it seems to be inpossible...
I use :
Debian Testing (Etch) Kernel 2.6.12 and packages obtained by apt-get
Snmp & snmpd 5.2.1.2
Cacti 0.8.6f
Lm-sensors
The sensors command is Ok
...
M/B Temp: +34°C (low = +15°C, high = +40°C) sensor = thermistor
CPU Temp: +45°C (low = +15°C, high = +45°C) sensor = thermistor
Temp3: +39°C (low = +15°C, high = +45°C) sensor = thermistor
The snmpwalk & snmpget command gives good result
Linux:/# snmpwalk localhost 1.3.6.1.4.1.2021.13.16.2.1
LM-SENSORS-MIB::lmTempSensorsIndex.1 = INTEGER: 0
LM-SENSORS-MIB::lmTempSensorsIndex.2 = INTEGER: 1
LM-SENSORS-MIB::lmTempSensorsIndex.3 = INTEGER: 2
LM-SENSORS-MIB::lmTempSensorsDevice.1 = STRING: M/B Temp
LM-SENSORS-MIB::lmTempSensorsDevice.2 = STRING: CPU Temp
LM-SENSORS-MIB::lmTempSensorsDevice.3 = STRING: Temp3
LM-SENSORS-MIB::lmTempSensorsValue.1 = Gauge32: 34000
LM-SENSORS-MIB::lmTempSensorsValue.2 = Gauge32: 46000
LM-SENSORS-MIB::lmTempSensorsValue.3 = Gauge32: 39000
Linux:/# snmpget localhost 1.3.6.1.4.1.2021.13.16.2.1.3.2
LM-SENSORS-MIB::lmTempSensorsValue.2 = Gauge32: 45000
I tried different methods to graph CPU temp
1) : Obtain OID value by SNMP Generic OID : With this method, i obtain a flat graph, with a constant value of 0. Looking at the Cacti Log, i can see that the OID is polled and the value obtained.
01/21/2006 02:25:18 PM - CMDPHP: Poller[0] Host[6] DS[53] SNMP: v1: localhost, dsname: snmp_oid, oid: 1.3.6.1.4.1.2021.13.16.2.1.3.2, output: 45000
When i try to change the value OID to an index OID (ex 1.3.6.1.4.1.2021.13.16.2.1.1.2) , the graph gives the correct value. The only difference between value OID and index OID is the format : Gauge 32 for temp, and INTEGER for index.
2) : Creating a new template based on Generic OID, including CDEF function to divide result by 1000 : Same result
3) : Using lmsensors sripts described on this forum : With this method, i dont obtain any graph !!!
I copyed the xml file in the correct path and imported the templates (net-snmp_lm_sensors_temp.xml) for snmp-queries, data-templates & graph templates .... Ok
I added the templates ucd/net - lm_sensors Temperature to the “linux local machine” host template
(in associated data queries section).
All the parameters seems to be Ok. When i createed the host, Cacti found the xml file and the sensors :

Re: Problem to graph CPT Temp
PYDou,
I had the same symptoms with another template: flat lines although snmpwalk turned valid results.
Im also using Debian Sarge testing, and cacti 0.8.6h (unstable package)
When looking at the mysql database with phpmyadmin, I found out that the OID values were empty. I completet them manually,, and that solved it for me.
Maybe this is also the solution for you.

hi,all
i'm not using lm-sensor
but i want to create graph for my netguardian temperature's
when i use snmpwalk for the OID temperature, i get this value
.1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10 = STRING: "........ 21.5035"
the real temperature is 21.5035 celsius
the problem here is when i run my snmpwalk for the OID temperature
i got value "........ 21.5035"
i dont understand, how can i get the real temperature value< 21.5035 not "........ 21.5035">
please help me to solve this problem, so i can graph for the temperature of my netguardian
thx b4:)

Hi, I'm getting this response when running a verbose query on cacti-0.8.6h looking for lm-sensors fan speed... this is the first one I've installed of the lm-sensors templates so I presume the others will have the same response.
My snmpd.conf is very limited, only has
so I'm wondering if that needs to be added to, to allow for lm_sensor monitoring.
Any ideas?

hi is therer a version vor 0.8.6c ? did you made lm sensors run and how ?dustsmoke wrote:Is there any way to get an export of these scripts for 0.8.6c?
