Monitoring total number of connections

[Tag]

Looking for an easy way to monitor total number of TCP connections to a host. Does the agent have any built in functionality to do this, or even seperate out ESTABLISHED, WAIT, etc. Is it possible if not, to do this without creating userparms.

Thanks,

Zabbix does not have the functionality built in. You'll need to create an external script.

netstat -t | grep ESTABLISHED | wc -l

would give you the current number of established tcp connections (I get the feeling you may already know, but it's there in case someone else is searching).

Here is a little bit more optimized version

netstat -t -n | grep -c ESTABLISHED

- Only 2 forks - but needs gnu grep but why not use it anyway? And it is standard on Linux.
- Does not query DNS - so it would be faster
