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 :

Code: Select all

+ Running data query [16].
+ Found type = '4 '[script query].
+ Found data query XML file at '/usr/share/cacti/resource/script_queries/lmsensors_fan.xml'

What should I do to make it work ?

RRDtool error

Post by cactiuser2 »

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:

Code: Select all

RRDTool Says:

ERROR: Could not parse line 'GPRINT::LAST:Current\:%8.2lf%s'
Any suggestions on how to fix this? I'm running v0.8.6i on Debian Etch.

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:

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

Am I missing something here as I've managed to get other graphs working under cacti (hddtemp,apcupsd,and other snmp ones) just not ones to do with lm_sensors.
Also I'm using the latest Cacti-0.8.7a on a gentoo box connecting to a couple of other gentoo boxes and an ubuntu gutsy box.
Cheers for any help in advance

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
