Hi folks,

I'm using collectd 5.4 to create counter type metrics using the Python
plugin but I only see NaN values in the file generated by the CSV
plugin. Here is the relevant code inspired by

def read_callback():
    offsets = get_offsets()
    for name,value in offsets.items():
        val = collectd.Values(plugin="foo", type="counter")
        val.type_instance = name
        val.values = [int(value)]


I know for sure that the value for a given name increases once in a
while but I only see NaN.
