I finally found something in a prior post that helped me solve my problem. I suspect that this may be your problem too. Delete or Rename your status.sav file. This is in ${prefix}/var/ This is only supposed to save the last state of each host or service, but it must be a bug in Nagios or the Docs, because it seems to also save the fact that Performance Data is turned OFF. As soon as I removed this file and restarted Nagios, I finally saw that performance data was enabled. Jack </BODY> </HTML>
