About rsmonitor

rsmonitor is a simple shell-script based server monitoring solution for unix-like servers. It uses ssh to connect to the monitored servers, and tries to use only standard tools to check the server status. Per default it checks network connectivity, memory, swap and cpu utilization, system load and uptime.

rsmonitor can also use per-server application testing scripts to check the status of the applications on a server. If a script with a name matching the server name is found in a dedicated appmon directory it is executed at each poll to get the latest application status.

Being simple and extensible rsmonitor can easily be extended to support other protocols than ssh to poll servers, and to support new platforms. Currently linux-2.4 and linux-2.6 like systems as well as openbsd systems are supported, IOS support to check Cisco switches and routers is planned.

Currently rsmonitor only reflects the current state. It does not support logging, it checks for state changes but does little to track them. Both these features will probably be added later, as well as a mechanism to notify admins (using email/sms) on health state changes.
