Eventlog Analyzer can't collect OS, Unix, Network devices log

Eventlog Analyzer can't collect OS, Unix, Network devices log

I'm using trail Eventlog Analyzer. At first, it collect OS, Unix, Network devices log data.
Now, it can't collect them, but collect application log.
I can see log data in syslog viewer but it doesn't display in Host Tab.
Not error. Eventlog also listen on 513, 514 port. Server status ok.  I turn off Firewall.
