Hi,
my config file:
check process nginx
with pidfile /dh/nginx/servers/httpd-ps93737/var/logs/nginx.pid #Pid file
for nginx in my case it located in /opt/nginx/logs/
start program = "/etc/init.d/nginx start"
stop program = "/etc/init.d/nginx stop"
if failed host www.mysite.com port 80 protocol HTTP then restart #set
your server IP that runs nginx
if 5 restarts with 5 cycles then alert
check program webserverresponse with path /home/myhome/webserver_response.sh
# if status == 502 then restart
if status == 502 then exec "/usr/local/bin/monit restart nginx"
depends on nginx
My /home/myhome/webserver_response.sh return 502, but not work, not restart
nginx.
I did something wrong?
thanks
