Hello, when i do command "netstat -nt|wc -l" i get around 1200. i would like to ask if i can use any Linux utility/command to monitor performance impact of the network connections. Ideally to see CPU/RAM/slowness impact. The server is 16+ threads, 4GB RAM free. I would like to safely determine how many connection is still good or if i need to decrease. Im not interested to see server load in general, or the work done as a result of the connection (showing a webpage for example), but just connection itself impact. Thank You
Try NewRelic - https://newrelic.com/ ... you can monitor almost all type of resources of your server.
I assume htop would be ideal. yum install htop If you are looking to real time monitoring service, check https://nodequery.com then if you prefer self hosted solutions netdata could be useful or munin; https://github.com/firehol/netdata http://munin-monitoring.org/ Have a great day!
