Is there a difference on the check_ping call when running the command from ssh vs. webgui?

It seems that mine fails on the WebGUI.

from SSH
[root@srv-mon-nsb1 libexec]# ./check_ping -H srv-files-nsb1 -w 10,100% -c 50,100%
PING OK - Packet loss = 0%, RTA = 0.41 ms|rta=0.415000ms;10.000000;50.000000;0.000000 pl=0%;100;100;0

from WebGUI
COMMAND: /usr/local/nagios/libexec/check_ping -H srv-web-nsb1 -w 10,100% -c 50,100% -p 5
OUTPUT: PING CRITICAL - Packet loss = 100%|rta=50.000000ms;10.000000;50.000000;0.000000 pl=100%;100;100;0

Just to verify, are you getting this output from the test command button or by letting the command run via normal nagios scheduler? Otherwise to my knowledge there is not a difference, unless selinux or something does not give the executing user permission to exit the system with a ping.

This is run from a SSH command line when it has success with the PING.

Is selinux enabled? Can you run the check from the cli as user apache? Have you tried configuring the check in XI and letting the nagios scheduler run the check normally (rather than using the test check command button).

hmm cannot run this command with the user apache.

Run the following commands and show the output:
