Hello everyone, I have a small problem that I am trying to resolve. I copied the retention.dat file the other day so that I could clear it out to get ever of our hosts a clean check. Since then the retention.dat file has not been populated with any data. I have even designated a new log file but it is still not getting any data. I have verified that everything in the nagios start script is pointing to the right file, and in nagios.cfg is correct. Has anyone else experienced this problem? I have tried restarting Nagios so many times but it is still not populating the data. Anyone know how I could correct this? Any suggestions would be appreciated. Thanks Joseph
