Amentet Monitoring Service
CORBA Server Monitoring service
The Amenetet Monitoring Service monitors remote services which register with it, heart beats are used in both directions to monitor the health of remote services. Remote services maintain a lease with Amentet and renew that lease regularly. Amentet then pings back to the remote service to monitor its health. Remote Services can monitor multiple objects internally, when "pinged" by Amentet, if any of these objects has disappeared an exception is thrown back with the list of missing objects. Amentet will store events in a local Db which can be viewed using the Web interface and as events occur alerts will be raised which can be sent to SNMP Trap daemon and/or SMTP and/or SMS. The service uses Spring Security Framework for access control and can be configured to use any Authentication Authorization system supported by the Spring Security Framework. -

Emon
Remote server monitoring application
Emon is another remote server monitoring application, but this time you are able to start your monitoring in the terminal easily. You do not need to install any applications on the monitoring servers, because Emon uses SSH and /proc directory to get the monitoring data. All you need to do is just configure Emon in XML and create an SSH user. After configuration, you are ready to monitor ping, dns, ports, url, CPU, RAM, SWAP, disk, traffic and log files of multiple servers in the terminal. If something goes wrong, Emon will send email to the admin. Emon is able to send the statistics (dropouts and graphs) to the admin.
