If the OS fails to execute a ping, does there exist a mechanism for the OS to
tell POE about that? And for me to 'notice' such an incident?
I was hoping that checking the return value on a 'post' would do that ... but
thus far, no dice (i.e. the box on which my script is running intermittently
fails to emit pings, but by script doesn't log anything.)
[...]
# "Pinger, do a ping and return the results as a pong event. The
# address to ping is $addr."
$result = $kernel->post( 'pinger',
'ping',
'pong',
$addr,
$timeout,
);
log_error("Problem pinging $addr: $!") unless $result;
[...]
