The keys net.tcp.port and tcp,port using what commands to perform the check?

[jrprado]

The keys net.tcp.port and tcp,port using what commands to perform the check? I searched in the sourcers and not found. I need that much of this information.

Appreciate the help!

Nobody knows the command?

The key net.tcp.listen know using the netstat command.

What is to net.tcp.port? and tcp,port?

Can anyone help me? Nobody knows the command?

I know this isn't an answer, but what if it isn't a unix command but a call to a kernel value or some such thing in /proc?

Please i really need a answer!

You could go through the C code. I'm pretty sure they don't use a unix command to do the check, but perform the checks by way of libraries with functions similar to unix binaries.

Repeated differently: Unix binaries reference libraries to do these TCP checks. So does Zabbix. In other words the zabbix_agentd process is what is making the call, by using the linked libraries.

$ strings /usr/local/sbin/zabbix_agentd | grep tcp
/proc/net/tcp
zbx_tcp_listen() Fatal error: unable to serve on any address. [[%s]:%hu]
net.tcp.listen
net.tcp.dns
net.tcp.dns.query
net.tcp.port
net.tcp.service
net.tcp.service.perf

Like I said in my previous post, it seems that it can and does get some information from the /proc filesystem. Otherwise it's doing TCP calls directly using the aforementioned libraries.

untergeek, thank you very much!

It is a way! I will do some research about it.
