I believe there Is a previous post about a bug in check_ping. Use

** **
I'm seeing a lot of false positive results from one of the host I'm
monitoring with the check_ping plugin. Looking at the logs I see various
degrees of packet lost for this host, but when a run the standard ping from
the command line don't have any packet loss. Does anyone have any insight
about this?
