I played with check_ping a little bit, and as far as I know it writes
something like "Could not interpret result from ping" when there's
something wrong...

I'm wondering how the output of ping could end up on check_ping's output
since the child's stdout AND stderr are both grabbed bt check_ping...

Don Munyak, if you want to verify whenever the actual ping ran and with
which args, you can add "-vvv" to the check_ping command and running it
from the command line. You should (shouldn't in your particular case)
get something like this:

$ plugins/check_ping -H localhost -w1000,10% -c2000,20% -p1 -vvv
CMD: /bin/ping -n -U -w 10 -c 1 localhost
Output: PING localhost (127.0.0.1) 56(84) bytes of data.
Output: 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.037 ms
Output:
Output: --- localhost ping statistics ---
Output: 1 packets transmitted, 1 received, 0% packet loss, time 0ms
Output: rtt min/avg/max/mdev = 0.037/0.037/0.037/0.000 ms
PING OK - Packet loss = 0%, RTA = 0.04 ms
1000.000000:10% 2000.000000:20%
