So how do we figure this value for X on the MIB?

Hello Barry,
Am writing an application that gets the IPMI data over the lan interface. Whatever that you have described here works only with Dell Servers because IPMI data is exposed thru SNMP by Dell Openmanage? I am not sure if the same OIDs work in other server machines. Please confirm.

Thanks,

Rajesh

On my systems the keyword “exec” changed to “extend” in snmpd.conf. And as the kipmi0 process is cpu hungry i changed my scripts to use an sdr dump file. See the -S option in the ipmitool manpages.

ipmitool sensors takes a long while to complete …

So, I use

ipmitool sdr type “Temperature”

ipmi-temp-stats has

printf “%f\n” `cat /tmp/ipmisensor-snmp |grep -v Disabled |cut -s -d “|” -f5|sed ‘s/degrees C//’`

But net-snmp does not like

the exec line in snmpd.conf

I tried extend; that didn’t help either.

I agree with George above – this is a great tutorial! I am also stuck in a similar place – everything works on SNMP, but not in Cacti. I am using 1950s instead of 1850s, so I don’t know if that creates a problem or not. I was able to get some of the fan speeds graphed, but I cannot get the CPU temps to work. IPMI reports our CPUs by relative temperature, so the numbers are negative. Could this be throwing Cacti off?

Also, how does the OID setup work for the data templates? If I want to see a certain value, can I put in the specific OID for that value rather than the generic OID that gets ‘walked’ across?

Great tutorial! I’ve gotten to the point where snmpwalk shows me the temp and fan speed values but I have no idea how to make them work in cacti. I’ve imported the host, temp and fan templates but I have no idea how to hook them up to data sources, graphs etc

I’ve created a device based on the host template but that’s about it Anyone that can give me a quick hand? I think cacti is awesome but way too convoluted when it comes to setting it up..

Always the same problem!!

# ipmitool user set name 1 enseleit
Could not open device at /dev/ipmi0 or /dev/ipmi/0: No such file or directory
Set User Name command failed (user 1, name enseleit)

# ipmitool user list
Could not open device at /dev/ipmi0 or /dev/ipmi/0: No such file or directory
Get User Access command failed (channel 14, user 1)

What’s the output of:

# lsmod | grep ipmi

You should have the following:

ipmi_msghandler
ipmi_devintf
ipmi_si

Any idea?

# mknod /dev/ipmi0 c 254 0
# chmod 777 ipmi0
# ls -la |grep ipmi
crwxrwxrwx 1 root root 254, 0 2004-06-30 21:04 ipmi0
# ipmitool -I open lan set 1 ipaddr xxx.xxx.xxx.xxx
Could not open device at /dev/ipmi0 or /dev/ipmi/0: No such file or directory
Get Channel Info command failed
Channel 1 is not a LAN channel!
