Monit is not able to detect that cassandra process is down

[Former user]

i am killing the cassadra process, but monit is not able to detect that process is dead on port 9042. i waited for long time(5mins to 30 mins), i did it many times, but monit was not able to detect that cassandra process was down.

Configs are as below :

cat /etc/monit/monitrc

set daemon 90
  with start delay 5

---

cat /etc/monit/conf.d/cassandra.conf

check process cassandra
  with pidfile /var/run/cassandra.pid
  start "/usr/sbin/service cassandra start"
  stop "/usr/sbin/service cassandra stop"
  if failed port 9042 for 2 cycles
    then restart
  if 3 restarts within 3 cycles
    then timeout

If the process died and monit detected it's not running, the port check is skipped. Monit should try to restart the processes and will resume the port monitoring after 2 cycles.

You stop monit and start it in debug mode to see details:

 monit -vI
