RE: Restart issue with HTTPD & SSHD

Hello Martin,


I have changed my code with what you sent:

start program = "/bin/bash -c '/etc/init.d/httpd start >>/tmp/httpd.output 2>&1'"


Now the Start & Stop work well. However restart does not work. I don’t think I would need the restart option, but I just want to things to be right. So would appreciate your help.


When I click on the restart button, the status changes to “Execution Failed”.  Same issue when I click restart button on the SSH process. Also can you let me know how to access the log file /tmp/httpd.output? I found no such file on my server.



Awaiting your reply!

it is possible the start/stop program failed because of some missing environment variable - monit purges the environment when executing the program for security reasons and sets only basic PATH variable. Monit doesn't log the output from the start/stop script by default, you can capture the output by wrapping the program like this:


    start program = "/bin/bash -c '/etc/init.d/httpd start >>/tmp/httpd.output 2>&1'"

I have installed monit and everything is running great, except httpd and sshd. My monitoring code is as below. The monitoring starts well when I start Monit for the first time. However if I restart or stop this from the web based control of Monit, I get “Execution failed” message.


## HTTPD monit config


check process apache with pidfile /usr/local/apache/logs/

group apache

start program = "/etc/init.d/httpd start"

stop program  = "/etc/init.d/httpd -k stop"


if failed host localhost port 80 protocol http then alert

if failed host localhost port 80 protocol http then restart


if cpu > 60% for 2 cycles then alert

if cpu > 80% for 5 cycles then restart

if children > 250 then restart


## SSHD monit config


check process sshd with pidfile /var/run/

start program  "/etc/init.d/sshd start"

stop program  "/etc/init.d/sshd stop"

if failed port 2511 protocol ssh then restart

if 5 restarts within 5 cycles then timeout



My log files also do not give clear details about this error.

Can anyone else?
