Typically the data issues are caused by rogue historical data. Sometimes data stored on the IBM i can also present issues. 

Because the data is collected by the IBM performance collector tools, ending the jobs and restarting them would be the first action to try:

  1. Disconnect the affected system(s) and on the IBM i use command STRSNP and take option 6 to end the Snapshot subsystem. 
  2. In QSYSWRK find jobs QYPSPFRCOL & QPMACLCT and end them immediately. 
  3. Once complete, then from the Snapshot menu take option 5 to restart the Snapshot collection. This will also restart the 2 IBM collector jobs you ended.
  4. Connect the system in the PC GUI and check if the data starts to be received.

If not then the next step is to disconnect the system again and move the component folder that is in error (so for example if your DISK data is corrupt, navigate to C:\Documents
and Settings\All Users\Application Data\MidComp International or Halcyon\SnapshotTSC, find the affected system and then move the DISK folder to another location (this ensures you retain the historical data).

When the system is reconnected the DISK folder will be created and the data stored on the IBM i will be sent through. Should the data on the IBM i side be corrupt, then either using the purge options or in certain circumstances deleting the agent and reinstalling will resolve the issue.

It's essential to always ensure that the same version is installed to all systems, so the IBM i agents and PC GUI must match.
