If the agent does go offline for a period of time, the kaseya server will notice this and the "last check-in" time will stay at the last time that the agent was seen by the server.
FollowThisLogicWe're in the testing / checking out phase. Right now we just use it for gathering info, so there's no sense in blowing bandwidth on it.
We had one client where a 30-second checkin time (on 21 client machines) was causing 1700ms+ latency to the internet on a full T1.... cut checkin time down, and like magic, the internet was normal again.
email@example.comThere are some serious issues with the router, your T1, or what you have configured with Kaseya if 21 machines cause such a latency problem.
We've got a few clients with T1's as well as regular broadband with 30+ computers and do not see any negative impact with agents checking in every 30 seconds.
