Hi, have you tried monitoring queues  of many servers?, I'd like to establish different alerts based on queue size (alert, warning, critical).

Hi, now we have Nagios, but nearly we are going to use Zabbix. I'd like to monitor queues os many namespaces on different servers, but show only alerts about size of queue (warning, critical), have you tried that with SNMP ?

Hi, send me a message with your email. 

We are working on that too.
