Hello!

Device: big-ip ltm 1600 series. I use zabbix to monitor device. I have LB configured on it, and I have to count number of rejects when simultaneous sessions reach limit. And send it zabbix. Is it possibe?

virtual test {
   limit 5
   snat automap
   pool test
   destination 10.1.1.1:http
   ip protocol tcp
   profiles fastL4 {}
}
application delivery

    i have seen no counter incrementing inside TCP profile while the VS was blocking. only info so far was ltm log with the blocking warning but it won't be enough to count anything.

    Hi Anna,

     

    if I right understood your question you can try to configure custom snmp trap, when connections reached limit. In /var/log/ltm event will be log something like this "Connection Limit Exceed .......".
