Nagios doesn't Trigger Continuous Alerts - nagios

Question

I have setup Nagios on one of my VM.
I receive the first alert when a service is Critical. But I do not receive the subsequent alert/email.
Host template config
define host {
name host-template
alias Default server template
check_command check_dummy!0!!!!!!!
max_check_attempts 10
check_interval 5
retry_interval 1
check_period 24x7
event_handler notify-host-by-email
event_handler_enabled 1
process_perf_data 1
contacts user1
notification_interval 10
notification_period 24x7
first_notification_delay 0
notification_options d,u,s,
notifications_enabled 1
_LTERM_LOAD_C 10
_LTERM_LOAD_W 5
_USED_MEM_C 30
_USED_MEM_W 20
_USED_SPACE_C 40
_USED_SPACE_W 30
register 0
}
Host config:
define host {
host_name aaaaa
use bbbbb
alias DEV
display_name DEV
address 11.111.111.111
_KEY xx
_SERVERPORT xx:8082
_SERVERPORTLFAT xx:443
_URL xx:8082
_USER test01
register 1
}
notification_interval is enabled but still i don't see any notifications.
I'm unsure if there is anything that is overriding it.

Answer 1

Because of this:
max_check_attempts 10
Nagios will try 10 more times before send you notification. Try to comment it and check again
