Collecting Data Failing with error="no such file or directory: "

[pbirokas]

I am about to run this exporter in our environment and wanted to try out what data this exporter can provide.

Unfortunatelly the exporter are unable to collect data.

# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

# rpm -qa | grep -i ipmi
OpenIPMI-modalias-2.0.27-1.el7.x86_64
freeipmi-1.5.7-3.el7.x86_64
OpenIPMI-libs-2.0.27-1.el7.x86_64
ipmitool-1.8.18-10.el7_9.x86_64
OpenIPMI-2.0.27-1.el7.x86_64

# which {ipmi-sensors,ipmimonitoring,ipmi-dcmi,bmc-info,ipmi-sel,ipmi-chassis}
/sbin/ipmi-sensors
/sbin/ipmimonitoring
/sbin/ipmi-dcmi
/sbin/bmc-info
/sbin/ipmi-sel
/sbin/ipmi-chassis

As you can see the Freeipmi package is installed and the binaries are available in the PATH env. When I start running the exporter locally on the host it failes to collect data:

Using the binries will provide some data from the interface:

What do I missing here?

Previously I was using the precompiled ipmi_exporter-1.6.1.linux-amd64.tar.gz from your releases.

I tried to give some more output and modified the sources. After building it from source it worked out and no additional output was needed.

So, for me, it looks like there is something broken with your last release.

Judging from the log output, it never gets around to even executing the command in the first place. My guess would be that the error originates from the attempt to create the temporary config file, but not entirely sure. Was there something specific that you changed that made it work?

[pbirokas]

Like I wrote, I just clone and build the exporter by myself. Before used the prebuild binary (ipmi_exporter-1.6.1.linux-amd64.tar.gz ) that causes the problem.

I did not change anything to make it work, just clone --> build --> works. So in my opinion the prebuild version was not working in my case.

If it works for others, than the case can be closed.

Closing this, as no one else complained so far.
