I use cacti for monitoring lmsensors on some servers - and on one I have trouble - in graphs I have all zero values on graph.
On command /usr/bin/php -q /var/www/cacti/scripts/netsnmp_lmsensors.php voltage 10.0.0.1, dKD:83ls, 3, User, Password, MD5, , [None], , 161, 500 query sensorReading I get this result:

Code: Select all

4:4.972

- In graph templates, select the template (8x thermals for exemple)
- In each Graph Item Input (Thermal Sensor 1, 2, etc...), tick the line AND gprints associated
- save and now smile watching your graphs ;)
Hello, please can you describe, where should be the line AND gprints associated ? Im watching to my Graph Item Input and there is no such line ...

Thanks in the advance ...

Core-temp improvement

Post by lbegault »

I made some modification to the script in order to support lmsensors core temp values (for multi core cpu). Here is the script, the new dataquery and a graph template for a 4x sensor.
Just a note: for graph the 1st value has a 100-value cdef as a workaround of the intel core-sensor bug.
Hope it can help someone.

fan graph

im using cacti 0.8.7b with net-snmp version 5.4.1 and sensors version 3.0.0 in ubuntu server edition 8.04.1 everything works fine after i update the script but in ucd/net - lmSensors - Fan Sensors i got this: This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information.

i run and get this:

Is there a way to make this work with dual CPUs?

I have a little problem here...

My graphs aren't working and when i run the verbose query, i gete the following message:

+ Running data query [11].
+ Found type = '4 '[script query].
+ Found data query XML file at '/usr/share/cacti/site/resource/script_queries/lmsensors_temp.xml'
+ XML file parsed ok.

+ Found data query XML file at '/usr/share/cacti/site/resource/script_queries/lmsensors_temp.xml'
+ Found data query XML file at '/usr/share/cacti/site/resource/script_queries/lmsensors_temp.xml'

When i run the script mannualy in console, i get the following error:
"No sensors were found"

So i think that my problem is that SNMP is not working...

How do i solve the problem?

So I created graphes for each Core * sensors but the graph always show 0.

What can I do to figure out what's wrong ?

Thanks in advance.

I uploaded a new version that should work with 0.8.6 and 0.8.7 including the SNMPv3 stuff in 0.8.7

Note that some of the file names changed, so it's best to do a complete installation according to the instructions in the first post

Within cacti the imported data queries look fine, and can see their corresponding XML files, I added the three sensors queries to the device, and created data sources and graphs OK, but the poller is complaining for each sensor value e.g.

04/15/2009 02:55:03 PM - CMDPHP: Poller[0] Host[6] DS[53] CMD: /usr/bin/php -q /usr/share/cacti/scripts/netsnmp_lmsensors.php temperature 192.168.1.232, public, 2, admin, *****, MD5, , DES, , 161, 500 get sensorReading 19, output: FAILED -- no matching sensors were found

Running the php script manually gets the same result, how can I trace more of what's going on inside the script?

Seems the problem is related to the index of the counters, the code is expecting the returned index value to be the requested index minus one, when the actual index being returned is the same as the requested index

Code: Select all

        $snmp_arguments[2] = ($oid[0][1] . "." . $cacti_request_index);
        $scratch = call_user_func_array("cacti_snmp_get", $snmp_arguments);

        if ($scratch == ($cacti_request_index - 1)) {

                $cmdoutput[0][0] = $cacti_request_index;
        }

        else {
                echo ("FAILED -- no matching sensors were found\n");

                exit(1);
I've changed the
if ($scratch == ($cacti_request_index - 1)) {

to be
if ($scratch == ($cacti_request_index)) {

and the script now retrieves values, but I just need to double check that I've not introduced an off-by-one bug

Edit: I've just checked the graph values and labels of each index displayed in cacti against the sensor names and values returned by lm_sensors, they all seem to tie up properly, so I think my fix is correct.

Re: FAILED -- no matching sensors were found

That's weird

NetSNMP maintains four different tables of sensor types. Each row of each table represents a different sensor of that type. The rows within each table are keyed by OID starting at 1, while internal index numbers start at 0. The code in question simply issues a request for the OID and then compares the internal value to the requested OID, in order to see if the sensor actually exists in the expected pool (this is a sanity test on the sensor type before the value data is manipulated and processed).

Here is the voltage sensor pool on my test system. As you can see there are eight rows with OID values from 1-8 while the internal index values are numbered from 0-7.

Code: Select all

$snmpwalk -v 2c -c community host .1.3.6.1.4.1.2021.13.16.4.1.1
LM-SENSORS-MIB::lmVoltSensorsIndex.1 = INTEGER: 0
LM-SENSORS-MIB::lmVoltSensorsIndex.2 = INTEGER: 1
LM-SENSORS-MIB::lmVoltSensorsIndex.3 = INTEGER: 2
LM-SENSORS-MIB::lmVoltSensorsIndex.4 = INTEGER: 3
LM-SENSORS-MIB::lmVoltSensorsIndex.5 = INTEGER: 4
LM-SENSORS-MIB::lmVoltSensorsIndex.6 = INTEGER: 5
LM-SENSORS-MIB::lmVoltSensorsIndex.7 = INTEGER: 6
LM-SENSORS-MIB::lmVoltSensorsIndex.8 = INTEGER: 7
Can you post the output from your host

Sure, mine seem to base at 1 rather than 0, I get the same result whether I do the snmpwalk locally on the machine with the sensors, or across the network from my cacti machine. Same also true for Fan and Thermal tables

Code: Select all

# snmpwalk -v 2c -c public 192.168.1.232 .1.3.6.1.4.1.2021.13.16.4.1.1

LM-SENSORS-MIB::lmVoltSensorsIndex.6 = INTEGER: 6
LM-SENSORS-MIB::lmVoltSensorsIndex.7 = INTEGER: 7

Im runing on an ubuntu box with latest version of lm sensors.

I get this output

giancarlo@Home-Server-Ubx64:/var/www/scripts$ snmpwalk -v 2c -c public 127.0.0.1 sensors
LM-SENSORS-MIB::lmSensors = No more variables left in this MIB View (It is past the end of the MIB tree)

hoever I do get a response when running sensors:

I have installed the latest version of the template following the instructions on the first post.

Single graphs are working like a charm :)

The problem is at the 8x templates:

RRDTool Says:

ERROR: the RRD does not contain an RRA matching the chosen CF
Any solution?
