I need to monitor a Linux server. I'm searching for a monitoring tool able to store system information (CPU, RAM disks usage, Apache and Postfix status, etc.) throughout the day and send an email every day with a complete report.Every monitoring tool I saw (nagios, monit, cacti, ...) has a web interface or it opens a port enabling a client access on the server. For security reasons I need to avoid this.Any suggestions?
Monitoring tool without web interface
