Doesn't work on 2.4

[KrisBuytaert]

On a RHEL 5 box with Python 2.4 I run into the following error

File "/usr/lib64/nagios/plugins/check_graphite", line 85
values = map(lambda x: 0.0 if x == 'None' else float(x), values)
^
SyntaxError: invalid syntax

Hmm, that's not great. I don't have any machine with 2.4 on it at the moment so I can't really help you. Basically this has only been tested on Python 2.7 so I'm not sure at which version this starts being valid syntax :(

Workaround is to install python26 next to pyton on EL5 boxen. The package is available in EPEL.
However that's not a workaround for everybody..
