Subject: mpstat, iostat: Use decimal point for FP values in JSON output
X-Git-Tag: v11.5.2~13
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a12a567b148f4dca8a695dfa6c51e186dee20e69;p=sysstat

mpstat, iostat: Use decimal point for FP values in JSON output

This patch sets LC_NUMERIC variable to "C" to make sure JSON output (as
displayed by mpstat and iostat commads) is locale-independent and
floating-point values use a decimal point.
This should make JSON output compliant with RFC7159.
