There isn't an existing plugin that I'm aware of that could do this.  It
would be fairly trivial to write one though...a shell script that does
something along the lines of:

netstat -apn | grep -c ":[jabberport]"

Would probably do the trick.  You could then either wrap that up in your
own plugin, or publish the value via SNMP and get it using the SNMP
plugin.
