Well, it seems that if apache is crashed, there is not pidfile, so  
monit doesn't perform any test according to the log files. If apache  
is running, monit performs it.

What can I do?

Log:
======
monit[20683]: 'apache2_webserver' succeeded testing protocol [HTTP] at  
INET[localhost:80] via TCP
monit[20683]: monit: pidfile '/var/run/apache2.pid' does not exist
monit[22347]: 'apache2_webserver' process is not running
monit[22347]: 'apache2_webserver' trying to restart
monit[22347]: Monitoring disabled -- service apache2_webserver
monit[22347]: monit: pidfile '/var/run/apache2.pid' does not exist
monit[22347]: 'apache2_webserver' start: /etc/init.d/apache2
monit[22347]: monit: pidfile '/var/run/apache2.pid' does not exist
monit[22347]: Monitoring enabled -- service apache2_webserver
monit[22347]: monit: pidfile '/var/run/apache2.pid' does not exist
