How can Zabbix monitor the number of TCP connections?

To monitor TCP connection count, you can utilize Zabbix’s network monitoring feature. Here are the specific steps:

1. Create a new host to be used for monitoring TCP connection count.
2. Install the Zabbix agent on the host and make sure it is configured and running correctly.
3. Create a new template on the Zabbix server for monitoring TCP connection count.
4. Add a new application to the template to monitor TCP connection numbers.
5. Count the number of established network connections using the ‘netstat’ command.
6. Apply this template to the monitored host.
7. Wait for a while, then check the value of the TCP connections monitoring item on the Zabbix monitoring interface.

By following the above steps, you can now use Zabbix to monitor the number of TCP connections. You can add this monitoring item to your dashboard to easily track changes in TCP connections at any time.
