SIM is a system and services monitor for ‘SysVinit’ systems. It is designed to be intuitive and modular in nature, and to provide a clean and informative status system……
It does this by consistently verifying that services are online, load averages are in check, and log files are at reasonable sizes. Many other SIM modules sport different and in-depth features to bring a well rounded tool to your disposal to stop otherwise common issues daunting internet hosts.

Now SIM has been configured you can add a cron.
./setup -c
If it says “Removed SIM cronjob.” then you must type it again.
./setup -c
SIM has been installed now
Quote:
In order for SIM to work properly, it must be executed regularly, and the best method for this is by using a cronjob.
By default, a SIM cronjob is automatically added during setup and set to run every 5 minutes. To add it or remove it later, you can execute this:
/usr/local/sim/sim -j
or
/usr/local/sbin/sim -j
