Free server availability software for windows

The System Availability Utility checks a list of systems to determine if they are online.
System Availability Utility returns valuable information such as Request Timed Out, Host Not Found and the Response Time in milliseconds and Resolves IP Address to DNS Host Name.
System Availability Utility is very useful for troubleshooting network connections and seeing which systems are online and which ones are problematic.

CleverEye is Availability monitoring software for servers, network appliances, databases and applications.
It queries servers and applications for availability. Technical reports are generated instantly. Service Level Agreement (SLA) reports prove you are exceeding best practices and standards. Monitoring now includes: FTP, DNS, Mailserver, Webserver and Database (MySQL, Oracle, etc.) tests.
Get increased insight on users experience. Firewalls, routers or ISP peering issues can hinder performance, know how it affects you? In a ten step process, know exactly where and why bottlenecks occur.
The friendly web interface makes it easy to add, edit nodes and tasks, and to find the info you need with drill down graphs, clear icons, status notices. Expanded ready-to-view reports ? include SLA reports, monthly, weekly, yearly. Get clear views for trend analysis and availability control. Be notified (email, SNMP Trap, etc.) of any availability problems (server down, response time exceeded, FTP availability, email performance). Graphs are clearer and include summary data.

With Server Watch you can monitor the status of up to 6 network connected objects, such as Computers, Printers, and Scanners.

Major Features:

1. File server capacity planning and performance troubleshooting are critical aspects of high-level network administration. Central file servers and distributed client workstations are now the norm in most corporate networks. This structure reduces storage capacity requirements, centralizes backup, increases the availability of files, and simplifies the document revision and review process. However, because data storage and access are centralized, performance limitations impact the entire network population. Accurately projecting the number of users that hardware can support under a specific workload, and understanding when and where bottlenecks occur, are critical to making efficient improvements to the server configuration.
2. File server capacity planning tools can be valuable in choosing new hardware for purchase, identifying the capacity of existing hardware, locating existing bottlenecks, and planning for resource expansion in advance of resource exhaustion. The throughput capacity of a file server can be expressed either as the maximum number of operations per second or a maximum number of users supported by the configuration. These values are influenced by several factors, some of which include processor speed, available memory, disk speed, network throughput and latency, and the speed with which SMB requests are processed.
