What tool do you use to monitor your servers?
I used the Nagios as a network monitoring software to check server's services status about 4-5 years ago. Now i need to monitor another network again and i am not sure if Nagios is still a good solution.I need a software with sending SMS and email on services fatal. the server i want to install tool on it is debian and the servers i want to monitor their services are windows and linux-based.
would you help me?
