Previously, if a single process used more than a terabyte of data, the following exception could occur:

File "/omd/sites/heute/lib/python3/cmk/plugins/collection/agent_based/systemd_units.py
    return cls(int(float(value) * {\"B\": 1, \"K\": 1024, \"M\": 1024**2, \"G\": 1024**3}[unit]))
KeyError: ''

This has been fixed. Thank you, Andy Wettstein, for this contribution.
