If there are 100 machines installed on each machine, running the SNMP service can be monitored,

Alarm words generally use nagios, more powerful than cacti, just out of the picture is not cacti good-looking.

===============================================================

Cacti monitor the number of concurrent connections netstat different network states

Netstat-n |awk '/^tcp/{++OLDBOY[NF]} END {for (a in Oldboy) print A, oldboy[a]} '

I do not know the Netstat status parameters can be man netstat view

Unzip the Get_netstat_conn.zip plugin program

# Unzip Get_netstat_conn.zip

Copy get_netstat_tcp_oldboytraining.pl to cacti root directory, authorization 755

Test the script to return the connection state data normally

Stress testing can be performed using the pressure test tool
