• If the discovery rule is on the read-write host, then the clickable name of the discovery rule should be displayed. (this works as expected)
  
• If the discovery rule is on the read-only host, then the non-clickable name of the discovery rule should be displayed. (this works as expected)
  
• If the discovery rule is on the inaccessible host, then the non-clickable "Inaccessible discovery rule" should be displayed.
  

In addition, the form of the host group must contain the line "Discovered by:" as it is done in elements/triggers/graphs.
