History data 🔗 link

Hi
I am using Hobbit v 4.2.  I am monitoring some Linux servers as well as Windows servers.  When I click on the 'HISTORY' button for any of the columns such as cpu, memory, etc.  I get a message saying "Cannot open history file".  I am able to see the history data for the Windows servers.  Can someone please help me how to resolve this issue for the Linux servers?

Thanks
