IIO is not returning any value

[arun2arunraj]

hi Team,

We are getting the following error message in one of our test server. Not sure why the IIO related details are not popping up. Any help would be much appreciated.

Note. I am running PCM as a docker image. In my host machine, I could see the pci.ids file. But I cant see the pci.ids in the docker image. Should I bind the hwdata into the container to get this metrics ?

/usr/share/hwdata/pci.ids file is not available. Ensure that the "hwdata" package is properly installed or download https://raw.githubusercontent.com/pciutils/pciids/master/pci.ids and copy it to the current directory.
Error info:event config file opCode-6-106.txt or /usr/local/share/pcm/opCode-6-106.txt is not available, you can try to manually copy it from PCM source package.
Event configure file have the problem and cause the program exit, please double check it!

I would assume that yes you have to make sure pcm in docker can access those files.

I think the main issue is that opCode-*.txt files are not available. Did you run "make install" inside the container to let pcm build process install opCode-*.txt files?
Not having hwdata is not a showstopper but to solve it you need to install the hwdata package inside the container.
