Alerts not listing properly in "Analyze/Alerts" screen of netwitness
What version are you currently running? Did anything happen around 9/14 that may have contributed to your alerts not appearing? Are you seeing any alerts or nothing at all after 9/14? What should be generating the alerts, ESA or the reporting engine?
If you feel that you would like more hands on support I highly suggest opening a RSA Support case so that we can take a look on a webex or we can request more specific information with nwtech/sosreport outputs.
