Agent Troubleshooting

Interactive config refresh failing

I found the interacive screens to refresh a host config did not always work. This includes using the "Refresh Configuration" button on the host screen or the Enterprise-Configuration-Refresh_Host_Configuration to kick off a configuration refresh job. From the affected agent home run:

./emctl control agent runcollection hostname.com:host ll_host_config 

If all is good you will get a "EMD runCollection completed successfully" message returned.
