This article provides information about legacy licenses in ipMonitor that are unlimited and new licenses that have a 500 monitoring limit.
All versions of ipMonitor
This issue can occur when migrating a system with an unlimited license before the license has been applied. If a system is migrated and running as an evaluation, the 500 monitor limit is in effect and you may see some monitors missing or inactive. The solution for this is to apply the license key.
If the maintenance expires on an unlimited license and it has been renewed, it would be a limited license. If maintenance is renewed prior to expiracy, the unlimited license is maintained.
