[Pkg-nagios-devel] Bug#353201: nagios-plugins-basic: plugins can fail if locale is set

[Hadmut Danisch]

Package: nagios-plugins-basic
Version: 1.4.2-6
Severity: normal

Hi,

check_procs does not work properly if used in Germany. 

Reason:

In Germany/Europe floating numbers are written with a decimal comma
instead of a decimal point. When you set LC_NUMERIC to something like
de_DE, the function sscanf expects a decimal comma, not a decimal
point.


check_procs calls 

  /bin/ps axwo 'stat uid pid ppid vsz rss pcpu comm args'

and then parses the output. That's where trouble begins. 
The %CPU is written as 0.0, but sscanf now expects a comma. It
therefore scans only "0", and leaves ".0" for the next argument, thus
shifting all subsequent arguments one to the right. 

check_procs -C something
therefore does not work anymore.

(Upstream bug reportet as #1433114)

regards
Hadmut
