ucd/net-SNMP lmSensors -- update Feb 10, 2007

[sithgunner]

I kept getting errors about making the graph to merge, so I messed around a bit and finally got it working. And here's my templates, for someone might save time I used to click several hundred times and increase about 100 page views on cacti web

Somehow I didn't have 8 data sources for voltage, namely -5V, and ended up having 3 fan readings, 3 thermal readings and 7 voltage readings.

These are the templates I used to work on *mine*.

As for the fans, I lost the 2 sensor readings (since I didn't have them turned on and deleted the entries) and never could pull it back, so I set 3 readings all on CPU fan... so, you have to fix that to suit yourself to read the other fan readings if you have them.

The posted update contains a fix that converts the SNMP timeout value from Cacti's millisecond format to PHP/Net-SNMP microsecond format. The lack of conversion in the earlier script would sometimes result in excessive retries or complete failure.

Sorry, i'm a beginner, and I don't "write" english well, but I'll try to explain my problem.

I've installed the plugin as said on this forum, but I can't make it work. When I try a verbose query, I obtain :

OK, forget that, I forgot to set the community name in the device configuration...

I got everything working with individual graphs, so I duplicated the 8x graph, deleted the last items, and then built a new graph with this new template. However, I get this error:

[filipe.montenegro]

Im new on cacti, and i dont now how to install new templates, so i import the file: "cacti_graph_template_sensors_ucdnet_lmsensors_thermal_sensors_8x.xml" and copy the scripts and the script_querry in the cacti folder..

i also add a new data query like this one:


when i debug the graph i see this:

im running cacti in my windows 2003 server... what i need to see the graph?

[filipe.montenegro]

help me!

[Alives]

I got tired of trying to roll my own net-snmp with lm_sensors included, so I just wrote a script that polls sensors -s and scrapes for the data. It also monitors hard drive temps using smartmontools. I will post as soon as I make sure all the bugs are ironed out.

I'm having a problem the the data query for lm_sensors at first I thought it was to do with snmp and lm_sensors not playing nicely but now I think they are. as when I run snmpwalk -v 2c -c public 10.1.1.248 sensors I get

[orion]

Never mind I found the update to the snmp sensors script. Still having a few issues though but I should be able to sort them out now

[skysurfer]

lm_sensors not working since upgrade to cacti 0.8.7a

need help plz

[orion]

Where exactly is the problem as I have it working with 8.7a

[skysurfer]

No sensors at all are found

[orion]

what do you get when you run snmpwalk -v 2c -c public <IP Address> sensors
do you get anything
