On some servers, we are able to navigate to the file through Browse but when clicking View, we cannot view the file contents with the following errors: 

"Open file failed: error" 
"Unable to locate '/var/log/cisco.log'" 

User-added image
UIM 8.51 
logmon 3.91 
robot 7.91 
CentOS 7 
This was not a logmon probe issue.  It was required to stop all the agent processes and then restart, which fixed the problem.  When permissions access is updated on a file system, all the parent and child processes have to be restarted for the permissions to take effect.
