Application fails to start.

[jbelant]

Hello,

I've just discovered monit, and have been experimenting with it. It 
looks like a great application, but I am having a problem starting my 
own applications.

I created a wrapper script, since my app doesn't set a PID file. The 
script looks like this.

#!/bin/sh
case $1 in
  start)
    cd /home/eminer/cA3Server
    ( /home/eminer/cA3Server/cA3Server > /dev/tty6 ) &
    pgrep cA3Server > /var/run/cA3Server.pid
  ;;
  stop)
    kill `cat /var/run/cA3Server.pid`
    rm /var/run/cA3Server.pid
  ;;
  *)
    echo "usage: rc.a3server {start|stop}" ;;
esac

I have tried this script with and without the '&' to detach the process, 
and monit can't control it either way. I can control the application 
from a console using this script, and it works. Using this script, monit 
can stop the application, but can't start it. A clip from my monit log 
looks like this.

[CST Mar 23 10:50:50] Starting monit daemon with http interface at [*:443]
[CST Mar 23 10:50:50] Starting monit HTTP server at [*:443]
[CST Mar 23 10:50:50] monit HTTP server started
[CST Mar 23 10:50:56] 'A3Server' stop: /home/eminer/bin/rc.a3server
[CST Mar 23 10:53:25] 'A3Server' stop: /home/eminer/bin/rc.a3server
[CST Mar 23 10:56:45] 'A3Server' stop: /home/eminer/bin/rc.a3server
[CST Mar 23 10:56:51] 'A3Server' start: /home/eminer/bin/rc.a3server
[CST Mar 23 10:56:52] monit: pidfile `/var/run/cA3Server.pid' does not 
contain a valid pidnumber
[CST Mar 23 10:56:52] monit: pidfile `/var/run/cA3Server.pid' does not 
contain a valid pidnumber
[CST Mar 23 10:56:53] monit: pidfile `/var/run/cA3Server.pid' does not 
contain a valid pidnumber

The PID file is recreated at start, but it is empty. Running the start 
script manually from a console correctly creates the PID file, with the 
proper PID.

Here is a clip of my monitrc file.

 check process ssh
    with pidfile "/var/run/sshd.pid"
    start program = "/etc/rc.d/rc.sshd start"
    stop program = "/etc/rc.d/rc.sshd stop"
    if 2 restarts within 3 cycles then timeout

 check process A3Server
    with pidfile "/var/run/cA3Server.pid"
    start program = "/home/eminer/bin/rc.a3server start"
    stop program = "/home/eminer/bin/rc.a3server stop"
    if 2 restarts within 3 cycles then timeout

I can use monit to control ssh perfectly. It may be a problem with my 
control script, but I haven't been able to find the problem. I have 
searched these archives, but haven't been able to figure this problem out.

Any help would be appreciated.

Thanks,

Jim Belant
