OSError: [Errno 22] Invalid argument

It happens for each process (like Nginx, uWSGI), even for diamond itself:

[[diamond]]
selfmon=True

Sample config which fails:

enabled = True
unit = B
cpu_interval = 0.0

[process]

[[diamond]]
selfmon=True

I'm using version 3.4.421.

Hi! I saw that you filed this as an upstream bug giampaolo/psutil#522 . Sadly, I don't think we can do anything on our end to fix it. We wouldn't be able to get any process information at all :(

[mlowicki]

Right. Let's close it as it's purely related to psutil.
