Nagios Event Handler is not triggering when the service is taking more time to response or down.

OK)
# The service just came back up, so don't do anything...
;;
WARNING)
# We don't really care about warning states, since the service is probably still running...
;;
UNKNOWN)
# We don't know what might be causing an unknown error, so don't do anything...
;;
CRITICAL)
Aha! The HTTP service appears to have a problem - perhaps we should restart the server...
Is this a "soft" or a "
hard" state?
case "$2" in
We're in a "soft" state, meaning that Nagios is in the middle of retrying the
check before it turns into a "
hard" state and contacts get notified...
SOFT)
# What check attempt are we on? We don't want to restart the web server on the first
check, because it may just be a fluke!
case "$3" in
Wait until the check has been tried 3 times before restarting the web server.
If the check fails on the 4th time (after we restart the web server), the state
type will turn to "
hard" and contacts will be notified of the problem.
Hopefully this will restart the web server successfully, so the 4th check will
result in a "soft"
recovery. If that happens no one gets notified because we
fixed the problem!

# The HTTP service somehow managed to turn into a
hard error without getting fixed.
# It should have been restarted by the code above, but for some reason it didn't.
# Let's give it one last try, shall we?
# Note: Contacts have already been notified of a problem with the service at this
