The agents don't do the processing. They collect the hashes and forward them to the server for analysis and alerting. The auto_ignore option is only valid on a server (or a local installation), not an agent. And I just tested it. I managed to get alerts after setting the auto_ignore option, even though there were 3+ previous changes to the monitored file. > Thank you, > > > > On Friday, July 22, 2016 at 12:36:53 PM UTC-4, dan (ddpbsd) wrote: >> >> On Fri, Jul 22, 2016 at 12:14 PM, EvilZ <[email protected]> wrote: >> > Hi Dan, >> > >> > I plated the<auto_ignore>no<auto_ignore> in the syscheck section and for >> > some reason it simply does not trigger. >> > >> > Is it possible that once it was triggered three times it goes in a do >> > not >> > check list that i have to reset ? >> > >> >> I don't think so, but I'm not positive.
