[Nagiosplug-help] check_ping

[Marc Belanger]

In my short experience with 2.03b, plugins-1.4 on Solaris, I've found that once I get commands to work from the command line, correctly add the service and checkcommand definitions, and restart the nagios daemon as the nagios user, my core problem has gone away.

"man signal" on FreeBSD simply shows a sigsegv for a signal 11. I am taking Subhendu's statement as truth that the error code minus 128 = signal called; from earlier in this (or a recently similar) thread. Here's what I followed;
http://www.freebsd.org/cgi/man.cgi?query=signal&sektion=3&apropos=0&manpath=freebsd

You state that its working now, but that it may be intermittant. My advice would be to recompile the check_ping plugin if the condition returns.

One other comment; the ranges you specify are in noticably higher than the defaults, my Solaris default w|c thresholds are 100.0,20%|500.0,60%; thats straight from the samples directory after ./configure; make; make install. Is it possible they are too high causing an out of bounds?
