[Perfparse-users] perfparsed & CPU usage

[Tim W. <tim...@gm...>]

Hello,
I configured perfparsed to read from a pipe. (Method 4) (config below)
I noticed that the CPU usage for perfparse is constantly at > 95% (sse
part of 'top' output below).

Without perfparsed, top reports 99.7% idle, with perfparsed, it
reports about 50% idle. I should add that this is a test setup, with
nagios checking only 60 services every 5 minutes (iow, perfparsed
takes up a lot of CPU for doing close to nothing)

the production setup checks around 600 services, so I'm a little worried.

Any thoughts, insights ?

Tim
