Discovery rules not discovering

[jmusbach]

Hello, I have setup a number of discovery rules that relate to the subnets our servers we want to monitor are in. Since I've gone ahead and installed the agent on these servers I've told these rules to check for the zabbix agent and query the key "system.hostname". After that I added two discovery actions to cover my bases, one to add hosts if the discovery status is up and service type is zabbix agent and another that adds hosts if the discovery status is discovered and service type is zabbix agent. All of these are enabled and the discovery rules are set to fire every two minutes. Yet only a couple hosts (out of 300) have been added so far so I have some questions...

1) Does this config seem valid? If not, what should I change and why?
2) Does the discovery rule delay specify how often the entire rule's subnet is scanned or how often each IP in the specified subnet is scanned?

Thanks.

As a update, never got this working for some reason. But found that setting up autoregistration worked best for us so went with that instead.
