Package: munin-node
Version: 1.2.6-6
Severity: normal
On systems with HZ value different than the 100 (ie. ia64
with HZ=1024), the graphs look incorrect - values are too
big or not displayed at all.
Attached is a patch for cpu plugin that scales the values
down to the assumed HZ=100. Value of HZ is acquired using
getconf CLK_TCK.
