Apache default template contains the following trigger whose event name can be very misleading for users:

• expression: 'last(/Apache by Zabbix agent/apache.uptime)<10m'
• event_name: '{HOST.NAME} has been restarted (uptime < 10m)'

Actually it's not the host being restarted but the Apache service.

Moreover, the following item prototype description is probably wrong:

• name: 'Bytes per request' 
• description: 'The average number of client requests per second.'

According to Apache documentation, this metric represent the "average bytes per request".
