IPS and Application

Question

I have notice that the IPS and Application seem to not be working their is nothing listed in the logs of IPS and Application for the pass week no activity. 
 I have tried nmap to try and trigger the rules of the ids and tried some of the applications that is on the application Deny list to trigger the Application filter but their was no logs 
 every thing was working it was blocking but seem to just stop, did not make any changes to the filter rules in the firewall tab logging is check under the rules, Web protection is work i can see logs for it. 
 what else can i do to test IPS and Application and get them back working.

HI , 
 As lferrara, suggested you may restart the IPS service under System service > Service by Clicking on STOP and START. 
 Secondly , check if application classification is enabled through Console. 
 Console> system application_classification show 
 It should be ON ,if OFF then run command console> system application_classification on. 
 Finally , you may check the service is running or not 
 console>system diagnostics show subsystem-info 
 Do not forget the Application filter policy applied on the Firewall rules.
