Couple of things to explain here.

STRM can deal with 2 main types of information sent to it, namely, logs and flow records.

You already have logs being sent to the device, which is good.  However, there are no flows being sent.

With the default installation, there are several rules and sentries already added and enabled on the system.  If you do have any offenses created, then there have no anomalous or undesired traffic sent to the device that have triggered any offenses.

To rectify this, we can either amend the default rules or create new rules that will trigger once we see the undesired traffic

We can access the rules from 2 areas, under the event viewer and rules or at the offense manager and then rules.

Also, note that sentries are applied to flow traffic being sent to the device and also flows will populate the network surveillance window.  If you are not sending flows to the device, then we will not see any activity under network surveillance and also no sentries will be looked.

Please note that the STRM is NOT a plug and play device, like, most SEIM devices, we must train teh device to learn what is normal and abnormal in our network and then fine tune the rules and sentries to only "fire" when we want them to.  This process can be longwinded but is definitely worthwhile to get the most from your deveice.

STRM is NOT the best (or the cheapest) log management server but it does do logging and flow/network monitoring very well, which seems to set it aside from the competitors.
