  • Over 400 improvements and fixes overall

Bug Fixes

  • criticalNewly compiled MIB's had not been visible in console
  • majorRemoved many unwanted (false) alerts. Alerts fixed: node down on nodes that have never been monitored yet, connection reliability degradation alert was triggering improperly, processor queue length alert is now related to number of cores and is not influenced by spikes.
  • majorInstalling service NetCrunch service on domain account was confusing for many users, now NetCrunch installs and runs on a Local System Account. Users which want to monitor their network using a domain account can switch NCServer service settings to the desired account manually (the account must have admin rights to NetCrunch server otherwise program has no access to its own data and computer).
  • major According to Microsoft documentation, NetCrunch was displaying only "non wizard" marked counters. It's well known fact that Microsoft does not read own documentation and perfmon displays counters at its own discretion: NetCrunch will now do the same. All windows counter are available.

  • majorProblem with Web Access on IE running in compatibility mode
  • majorFree Disk space top chart did not show Linux/Mac/BSD volumes
