Remote logging

Hello guys,

Does anyone know how will act FortiGate when it's configured to send logs to remote syslog server and this syslog server become unavailable? Is it possible to configure FortiGate to deny the user traffic if logging for this traffic fails for some reason?

I suppose that if remote logging fails FortiGate will temporary store logs to a temporary buffer or queue. Is it possible to configure somehow the limit of this queue?

I have searched docs for info on this topic and i didn't find anything relevant.

If somebody have some information on this issue or maybe some relevant links I would be very grateful.

Thanks in advance!
