Multiple commands specified Error

[wilula]

Hello i am trying to provide additional argument for dcmi, but it fails to scrap with Multiple commands specified error. Everything else seems to work fine. Thanks in advance for help :)
This is config for this module

                user: "user"
                pass: "password"
                driver: "LAN_2_0"
                privilege: "admin"
                collectors:
                - dcmi
                - bmc
                - chassis
                - ipmi
                custom_args:
                        dcmi:
                        - "--get-system-power-statistics"  ```

Hello,

it is very hard to read your config snippet, it would be better to paste it in a proper code block (in triple backticks).

From what I can tell, you want to pass --get-system-power-statistics as additional argument to the ipmi-dcmi executable (which is used by the dcmi collector). However, there is no need for this: the collector already passes this argument by default (see collector_dcmi.go).

What is it that made you try this in the first place? Is something not working?

[wilula]

Sorry, i corrected the code block. When i delete the additional argument, exporter don't return any error but i can't see the desired metrics (current power, maximum power etc.) the only one is ipmi_dcmi_power_consumption_watts but when i launch the ipmi-dcmi directly with --get-system-power-statistics there are more parameters returned. Could You have any idea why the exporter won't return them ?

[bitfehler]

can you please post the exact ipmi-dcmi command you are executing (minus any passwords of course) and the output?

[wilula]

Yes of course :)
The command:
/usr/sbin/ipmi-dcmi -h 192.168.1.1 -u -P --get-system-power-statistic
The output:

Current Power                        : 119 Watts
Minimum Power over sampling duration : 59 watts
Maximum Power over sampling duration : 927 watts
Average Power over sampling duration : 104 watts
Time Stamp                           : 08/30/2022 - 09:22:16
Statistics reporting time period     : 3442792824 milliseconds
Power Measurement                    : Active

I don't' know if this is correct because the metrics are returned in different time frame but ipmi_dcmi_power_consumption_watts is the same value as Current Power here ?

[bitfehler]

Ah, I see now. Yes, ipmi_dcmi_power_consumption_watts is "Current Power". The reason that you don't see the other metrics is that the exporter ignores them, because they are aggregations, so they make no sense in a metrics database. You can easily get minimum/maximum/average power consumption for any time frame you see fit by using the respective Prometheus functions on your ipmi_dcmi_power_consumption_watts time series.

You are right, I just stated playing with additional arguments and didn't connected dots :) Thank You for clearing this out !
