Monit Configs for Ubuntu / Debian / CentOS / RHCE / Redhat

/2 Comments/in , , , , , , , , , , , , , /by

Note:
I have removed the checking of permissions of init and binaries. The extra system resources and maintenancefar outweighs any benefit.

Assumptions:

Completed: CentOS 6 / RHCE 6 / Redhat : Monit ( Server Monitoring and Automatic Maintenance ) or Ubuntu LTS : Monit ( Server Monitoring and Automatic Maintenance ) or Debian 7 wheezy : Monit ( Server Monitoring and Automatic Maintenance )

Monit config files for various services

Please only install the configs for services which you require.
