It worked like a charm. Is there a way to enable NSM (<br>> Network Security Monitoring) in Suricata which is currently configured<br>> for both IDS and IPS mode?<br>
<br>What do you need from an NSM, just packet capture?<br>
<br>NSM functions are somewhat documented here:<br>

I am not sure about NSM feature in Suricata. What is it used for and how does it help us. Are there any benefits of NSM features available in Suricata?
