SAP Audit log files - few application servers

Hi,

please your help,

We are tring to get online alerts from the audit log file(s),

We have 4 appliction servers, but, We get alets/events only from one appliction server - #2

in SM20 I can see all the events,

I would expect to see four separate log files (audit files), but find only one.

Settings on each of the servers are the same, (RZ11 - DIR_AUDIT, FN_AUDIT),

The same location on the network, the same file name. (Exactly the same, \\vfssh1\app\BznApps\SapProd_Data\BASIS\AUDIT).

In the path we find only one file per day and when we use the alerting application (ArchSight) we can see events only from server no.2

any ideas?

Is there a way I can read the audit log file to make sure it contains  also records other than server # 2.

Thanks,

Perez.
