F5 Malicious Source IP Address Alert

Ok, we have Graylog for that. But do you know what kind of alert is sent to the log server, since I can't see that now because it's rotated out.

And do you know if F5 has any form of alerting for this type of thing? It is strange to me that a system that big can't send alert emails when something happens and no one is looking at the screen atm.

Thanks,

Igor
