Sounds like your missing LM_sensors support in snmp
what Linux distra are you using?

i'm getting my tems in the misc section of snmp, is there a way to read these values in cacti?

can this be done by a simple adjustment to the php script, or can i make snmp to reportback with the correct names?

Probaly the reason for my temps showing up in misc is the kernel patch i have to apply for my temps to show

I think all you need to do is relabel the temps correctly and then it should pick them up. I believe they have to be temp1,temp2.. etc

Not sure how to do tat though I think you just need to put them into the conf file /etc/sensors.conf but I could be wrong

that's the weird thing, in sensors.conf the sensors are named correctly :

chip "f71882fg-*"

# Temperature
label temp1 "CPU"
label temp2 "System"
ignore temp3

and if i check phpsysinfo the correct temps are beeing displayd

lmsensors via smpt and cacti 0.8.7a

Post by tiger.tw »

skysurfer wrote:lm_sensors not working since upgrade to cacti 0.8.7a

need help plz :)
I had some trouble to setup this plugin in cacti 0.8.7a, too.

I tried to get it working with snmp V3. But it looks like there are some changes in version 0.8.7 regarding snmp, so i had to alter some of the plugin scripts. Now they work fine (for me).

Does someone know who is maintaining this project?
Perhaps my changes will be usefull

Find my modified version for cacti 0.8.7a attached to this post.
No guarantee that it is working for everyone. I am using it with snmp V3.

I have not made any changes to the templates.
Only files in "scripts" and "script_queries" directory were altered.

Happy testing...

I had compiled net-snmp-5.2.4 (got other problems with newer versions, so i used the older one) myself on SuSE Linux 9.3, SuSe Linux 10.0 and Debian Etch with the following compile-string.

Code: Select all

./configure  '--prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--with-sys-contact=root@localhost' '--with-mib-modules=host ucd-snmp/pass_persist misc/ipfwacc smux ucd-snmp/diskio tunnel disman/event-mib ucd-snmp/lmSensors' '--with-persistent-directory=/var/lib/net-snmp' '--with-libwrap=/usr' '--with-libs=-lsensors' '--sysconfdir=/etc'
Using lmsensors 2.9.1 on SuSE and lmsensors 2.10.1 on Debian

Cannot say more on this.

Does this patch work for other downloaders?

well, it actually was quite simple. Once i've changed snmp query in netsnmp_lmsensors.php it just worked.

This can be done with the fans aswell, in my case they're in the misc categroy aswell.

well... i am stupid! :P

the problem was that lm_sensors 3.x wasn't compatible with my net-snmp version.

a downgrade did the job. everything's fine now

thank u all for the help! :)

Do I have to change anything in sensors.conf? I checked the file, and it seems like everything is labeled with temp1 etc?

Some informations about your system like OS and versionnumbers of sensors, snmp, cacti, plugin, etc. could be helpful to help you ;-)

Ah, ok :)

I am running a Fedora 6 machine with a recently upgraded 0.8.7b Cacti.
RRD 1.2.x, net-snmp 5.3.1

I am trying to poll another FC6 box running net-snmp 5.0.1 ans sensors 2.6.3. As I wrote before, the snmp walk works fine, but not the query...
