ucd/net-SNMP lmSensors -- update November 11, 2010

[ehall]

Well apparently the data queries weren't included

I've uploaded a new tar.gz file which has the data query exports (and which include the one-off graphs as dependencies), the 8x graphs as separate exports, and the needed script.

Import the XML files, copy the script to cacti/scripts/, add the data queries to the target device and you should be good.

[Cornfed]

The queries show up, but I'm getting this:

Code: Select all

+ Running data query [11].
+ Found type = '4 '[script query].
+ Could not find data query XML file at '/data/cacti/resource/script_queries/lmsensors_fan.xml'
+ Error parsing XML file into an array.
+ Could not find data query XML file at '/data/cacti/resource/script_queries/lmsensors_fan.xml'
+ Could not find data query XML file at '/data/cacti/resource/script_queries/lmsensors_fan.xml'
+ Could not find data query XML file at '/data/cacti/resource/script_queries/lmsensors_fan.xml'

Clicking on the data query for more info gives me the screenshot

[ehall]

Okay I updated the archive again

1) use the "Import Templates" menu to import the XML files in the
templates directory

2) manually copy the XML files in the script_queries directory to
$cacti/resource/script_queries/

3) manualy copy the php scripts in the scripts directory to
$cacti/scripts/

[Cornfed]

Perfect!! I'm in!

Thank you!!

How did you get this running on an IBM system? My lmsensors refuse working on IBMs due to some BIOS overwrite "feature" somw years ago ...
Reinhard

[Instigater]

It's on Gentoo Linux.

Basic emerge lm_sensors did the trick.
Support for all possible hardware monitoring chips was compiled as kernel modules. Also don't forget to compile I2C support too.

I believe that quite recent version of kernel and lm_sensors will work on other distros too.

I got some trouble importing cacti_graph_template_ucdnet_lmsensors_fan_sensors_8x.xml

This is the error I get:

Have you an idea to solve the problem ?

You have an 8x Template but only three data sources ...

[sumsum]

hello cool script !

i have a problem after importing the templates and doing everything in place as you mentioned in the readme

the verbose data querry shows for example

but the status shows : Success [0 Items, 0 Rows]

did i lost something ?

tom

[skaag]

I'm running version "0.8.6c-7sarge3" (Debian)
I keep getting this message whenever I try to import templates:

Error: XML: Hash version does not exist.

I really need to monitor lm-sensors... my colo has heating problems and I want to show them facts.

Is there a way to get around this?

Thanks!

[sumsum]

you need to upgrade your cacti installation to version cacti-0.8.6h then the import of the templates will work.
cheers
tom

[skaag]

Ok now I am using 0.8.6h and i've copied the files again, and now i've managed to import all the templates, except for the 8x templates. I can't import the 8x templates, and i'm getting the same errors as Azoff is getting (Unmet dependencies while importing).

The simple graphs are working great now, I get all the data I need, but it would indeed be nice to have them consolidated into one graph.

Is there a solution for those dependencies?

Are the dependencies an issue of me not having all the data sources required by the graph? Or is it something else?

[Yzo]

I'm a new Cacti user and a net-snmp lightweight. I've been spending the last two days banging my head against the wall, trying to figure out how to get this working. My apologies if this post is excessively large, I'm striving to be as detailed as possible.

For some reason I haven't been able to figure out, no RRD files are being generated when I try to get these graphs working. I'll limit my examples to the thermal sensors, but the same problem is affecting voltage and fan readings as well.

The server in question is running Gentoo. lm_sensors, net-snmp, and Cacti were all emerged in. Cacti version is 0.8.6h_p20060108-r2, lm_sensors version is 2.10.0, and net-snmp is 5.2.1.2-r1.

Cacti is polling snmp via the lo or eth0 interface. With either interface, the Cacti standard graphs in the Linux host template work, but the lmSensors graphs do not.

CLI lm_sensors works. Here's the snipped output of sensors:

Code: Select all

temp1:       +53 C  (high =   +66 C, hyst =   +16 C)   sensor = thermistor      
temp2:     +52.0 C  (high =   +85 C, hyst =   +80 C)   sensor = diode           (beep)
temp3:     +41.0 C  (high =   +85 C, hyst =   +80 C)   sensor = thermistor      

CLI snmpwalk returns sensors readings. Here's that snipped output:

Code: Select all

$snmpwalk -c sakura -v1 localhost tempsensors
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: temp1
LM-SENSORS-MIB::lmTempSensorsDevice.2 = STRING: temp2
LM-SENSORS-MIB::lmTempSensorsDevice.3 = STRING: temp3
LM-SENSORS-MIB::lmTempSensorsValue.1 = Gauge32: 53000
LM-SENSORS-MIB::lmTempSensorsValue.2 = Gauge32: 53000
LM-SENSORS-MIB::lmTempSensorsValue.3 = Gauge32: 41000

I've got the requisite XML files and php scripts where they need to be according to the README. I import the thermal sensor data query template and the single sensor graph template. So far, so good.

I add the lmSensor data query to the device. Seems to be working. The status says "Success [6 Items, 3 Rows]". Here's the output of verbose query:

Code: Select all

+ Found data query XML file at '/var/www/localhost/htdocs/cacti/resource/script_queries/lmsensors_temp.xml'

I interpret that to mean it found the thermal sensors. So I go to create graphs for the host.



So now I've got three thermal sensor entries in the data sources tab, and three thermal sensor entries in graph management. Up to this point, I'm assuming everything is setup the way it supposed to be.

At this point though, I hit trouble. None of the rrd files listed in the data sources ever get generated. Here's the debug output for the temp1 sensor:

Code: Select all

/usr/bin/rrdtool create \

Obviously, if no rrd file is created, I'll get no graph output as indicated by the temp1 graph debug:

If I manually su to the apache user account and run the "rrdtool create" command above, I'll get an rrd file which when graphed results in a graph with no data. The values will be reported as "nan".

It looks for the world like cmd.php isn't even polling the information like it should. I created a device entry that contained only the lmSensors data queries and the associated graphs. Cmd.php logs the following (This is with logging set to HIGH and with poller logging Errors, Warnings, and Statistics):

Code: Select all

apache$ /usr/bin/php /var/www/localhost/htdocs/cacti/poller.php

Quite honestly, I'm a little out of my league when it comes to rrdtool and snmp. As far as I can see, it looks for the world like it should be working.

It's not a permissions problem, as I said, there's no problem with the data for memory usage, interface statistics, etc being written out and graphed.

Can anyone help?
