ipmi_exporter could not get datas in my environment

[ljhmily]

hi there, this is my environment：

cat /etc/centos-release

CentOS Linux release 7.1.1503 (Core)

rpm -qa | grep -i ipmi

ipmitool-1.8.18-10.el7_9.x86_64
OpenIPMI-libs-2.0.27-1.el7.x86_64
freeipmi-1.5.7-3.el7.x86_64
OpenIPMI-2.0.27-1.el7.x86_64
OpenIPMI-modalias-2.0.27-1.el7.x86_64

cat bmc.yml

modules:
default:
user: "Administrator"
pass: "pass@2O2O"
192.168.3.246:
user: "Administrator"
pass: "pass@2O2O"
privilege: "admin"
driver: "LAN"
collectors:
- ipmi

then execute ipmi_exporter with the configuration file

./ipmi_exporter --config.file bmc.yml --log.level=debug

and visit 9290, input 192.168.3.246 as target, the web display:

Hi!

you are using the lanplus driver for ipmitool, but driver: "LAN" in your exporter config. You most likely want to use driver: "LAN_2_0", which is the equivalent of 'lanplus for FreeIPMI. Let me know if that helps.

[ljhmily]

i changed driver, but not works.
driver: "LAN_2_0"

[ljhmily]

emm, it worked, while i put the driver to default module, why? is this need i place all my parameter to the default module? and then the custom module input what?

[ljhmily]

It requires me to put all the parameters (account, password, driver, or whatever) into the default module, so how do I monitor if I have dozens or even thonds of physical devices?
if the default module is null, or it have the user/password parameters, and the value is null or errorvalue, then the ipmi_exporter could not get data.

[bitfehler]

The prometheus server has to set the module when scraping the IPMI exporter. Currently, you can see in your logs that it is using the default module: target=192.168.3.246 module=default.

To change that, you have to change your prometheus configuration (not the exporter config). Please see this section of the docs, specifically you will need the last code block at the very bottom. But please read the entire section carefully.

Closing this, as it seems to be resolved. Feel free to re-open if not.
