Errors when installing on ARM

[Robie Basak]

Setting up collectl (3.6.3-1) ...
Starting collectl: collectlpcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.
sh: 1: /usr/sbin/dmidecode: not found
.

On ARM, there is not necessarily any PCI bus or DMI facility, so there should not be an error generated here.

Note that the postinst does exit with a zero status, and AFAICT collectl does work correctly once installed. If this is not the case, please could someone affected post a test case?

Status changed to 'Confirmed' because the bug affects multiple users.

Yes, it seems to work correctly, despite the error messages, though I'm primarily using collectl to feed disk I/O metrics into Ganglia. I brought up the issue as primarily "fit and finish".

However, I did not look into what dmidecode is used for, so I don't know whether some part of the functionality is impacted. There may be information obtained from it that could be obtained from elsewhere on ARM/non-DMI systems.

trevor - good catch, again! ;)

collectl uses dmidecode for only one thing - if you're doing environmental monitoring with -sE, it then uses dmidecode to get the product name which is then used in a lookup table of how to interpret the ipmitool output based on the model. so the quick answer is it's fine if it can't read it and all the stats will still be correct. It also store the product name in the header of the output files as a handy reference in case you're sharing logs with someone else or looking at them on another system, which is also harmless if it can't be written.

clearly I should be trapping the error and simply setting the product name to blanks if dmidecode is not there.

I'll get that into the next release too.
