GFI Network Server Monitor 7.0 b.20070803

GFI Network Server Monitor automatically monitors the network & servers for failures. It allows you to identify issues and fix unexpected conditions before your users (or managers) report them to you! Alerts can be sent by email, pager or SMS. Actions, such as rebooting a machine, restarting a service or running a script can be done automatically. GFI Network Server Monitor is easy to set up and use, and is competitively priced.
Built-in monitoring rules include: Exchange Server 2000/2003, MS SQL, Oracle and ODBC databases, CPU usage, FTP & HTTP Servers Group Membership, Active Directory & NTDS, Disk Drive health, Disk Space, Event Log (with content checking), File Existence (with content checking), TCP, UDP, ICMP/Ping, SMTP & POP3 Mail Servers, Printers, Processes, Services, UNIX Shell Scripts (RSH), SNMP & Terminal Server.
You can also write custom monitor functions in VBscript and leverage ADSI and WMI, allowing you to monitor virtually anything.
