Is possible than a router generate each eight hours a ping to a IP address predefined?

Possibly an EEM applet, maybe something like the following. Check out the link below, it has some great info about this sort of thing.
event manager applet email_server_unreachable
event track 10 state down
action 1.0 syslog msg "Houston we have a problem. Ping failed, server unreachable!"
action 1.1 cli command "enable"
action 1.2 cli command "del /force flash:server_unreachable"
action 1.3 cli command "show clock | append server_unreachable"
action 1.4 cli command "show ip arp 172.16.1.55 | append server_unreachable"
action 1.5 cli command "show ip route 172.16.1.55 | append server_unreachable"
action 1.6 cli command "show interface FastEthernet0/1/1 | append server_unreachable"
action 1.7 cli command "more flash:server_unreachable"
action 1.8 mail server "$_email_server" to "$_email_to" from "$_email_from" subject "Server Unreachable: ICMP-Echos Failed" body "$_cli_result"
action 1.9 syslog msg "Server unreachable alert has been sent to email server!"
I copied the info from: https://learningnetwork.cisco.com/blogs/network-sheriff/2009/06/19/writing-your-first-eem-applet

Thanks Jason,
But, How do I run the TCL file?

You could use TCL and if you have 12.3 IOS (might be 12.4) you can run a kron to kick off the timer. You are going to have to work out the details on notification of failures, etc, because I am just learning EEM and TCL myself.
TCL: save this code as "ping_ip1.tcl" (or whatever you'd like, just make changes below to reflect the new filename). Once saved, load into flash, or onto a TFTP server. If you store anywhere other than flash, be sure to change the IOS kron line below (tclsh tftp/ftp/disk0/etc).
foreach ip {
10.0.0.1
10.0.0.2
10.0.0.3
} {
ping $ip
}
IOS:
kron policy-list ping_ip1
tclsh flash:/ping_ip1.tcl
kron occurrence ping_ip1 in 8:0 recurring
policy-list ping_ip1
Edit: See this script for an example of how to get email notifications... http://forums.cisco.com/eforum/servlet/EEM?page=eem&fn=script&scriptId=2365
