Howto monitor and restart services automatically

[albatroz]

I wonder if someone has a script that can be linked to CRON for restarting services when
they suddenly stop working.

cpanel all ready has it is called chksrvd you can configure it with your service manager

cPanel and WHM actually has such a script built-in. You can add any service you want to /etc/chkserv.d/chkservd.conf

Chkserv supports two types of monitoring:

1 - Connection based monitoring: Chkserv will send out a request and anticipate an expected response. If it does not receive the expected response, it will attempt to restart the service. The syntax for adding this type of monitoring to chkservd.conf is as follows:

- service[serviceName] = port,send,response,restart
serviceName = Name of service
response = Expected Response
restart = Full path to restart service
send = What data to send

2 - Command based monitoring: Checks to see if a service (command) is running locally. If not, it attempts to restart it.
- service[serviceName] = ,,,restart,command,owner
command is a regular expression

Chkservd will monitor services periodically, once every 8 minutes.

In my case this is the content of chkserverd.cnf

named:1
named:1
named:1


However there are 3 other files called
clamd
cpsrvd
eximstats
named

For instance this is the content of the clamd file
service[clamd]=x,x,x,/scripts/restartsrv clamd,clamd,root

You can easily adjust your basic services via the "service manager" in whm. Check the box on the right of the service you would like monitored.
