[monit] Dreamhost Configuration

[Tom Coady]

Hello. I used to use monit to save my life while my server kept crashing, and am now seeing something similar on another host. I wonder if anyone might be kind enough to comment on my configrc as I'm getting too many alerts and I'm not sure if I set it right.

check file apache_bin with path /dh/apache2/apache2-ps18939/apache2-ps18939-httpd

#    if failed checksum and

#       expect the sum 8f7f419955cefa0b33a2ba316cba3659 then unmonitor

    if failed permission 755 then unmonitor

    if failed uid root then unmonitor

    if failed gid root then unmonitor

    alert address@hidden on {

          permission, uid, gid

        } with the mail-format { subject: Alarm! }

    group server

check process apache with pidfile /var/run/apache2-ps18939-httpd.pid

    start program = "/etc/init.d/httpd2 start" with timeout 60 seconds

    stop program  = "/etc/init.d/httpd2 stop"

#    if cpu > 60% for 2 cycles then alert

#    if cpu > 80% for 5 cycles then restart

    if totalmem > 400.0 MB for 5 cycles then restart

    if children > 250 then restart

#    if loadavg(5min) greater than 10 for 8 cycles then stop

    if failed host sussexheights.org port 80 protocol http

       and request "/wp/index.php"

       then restart

#    if failed port 443 type tcpssl protocol http

#       with timeout 15 seconds

#       then restart

    if 3 restarts within 5 cycles then timeout

    depends on apache_bin

    group server
