In appache and snmp few terms meaning
 

Dear List,
In one server there is centos 5 operating system. There runs a webserver by appache 2.0. We are using a monitoring server(opennms). In the resourse graph, we can find the following terms, Can anyone please please explain it.

Tcp open connections
Current Tcp connections
Context



Also what is concurrent connection in appache? how we change the it in http.conf file?

well tcp open connections is presumably the number of open active connections, i'd guess that the current connections is all connections in all states, not just open, and context i've no idea... what is the context for the word "context"?

concurrent connections would be how many connections are allowed at a single time.
