OSSEC monitors the health of the system from an internal perspective. It basically monitors logs. Nagios/Icinga monitors the system from an availability perspective. For instance, Nagios can tell you when it thinks a system is down and it can not connect to it or the available memory but it can not tell you that badguy gene has been trying to get logged into you system.
The two are completely different, but some do use OSSEC to monitor some of the system information like Nagios/Icinga does.
