Hi,<br><br>While testing and deploying Nagios I used the following service definition:<br><br>max_check_attempts 1<br>normal_check_interval 1<br>retry_check_interval 1 <br><br><br>Everything was configured and tested including nagiosgrapher (rrdtool). It passed proof and concept and we have now moved it into production. We tested this against a small set of 200 servers.<br>
<br>Then we went to our "production" values of:<br><br>max_check_attempts 3<br>normal_check_interval 5<br>retry_check_interval 1 <br><br><br><br>Data collection still works, but when we try to view a graph it's basically empty data (nothing drawn) for the period in which the new normal_check_internal was changed. If we change it back to 1 from 5, it starts to display data correctly again.<br>
<br><br>How do I *keep* the new normal_check_internal value, but make it work again? Googling led me to this:<br><br><a href="http://forum.centreon.com/archive/index.php/t-4506.html">http://forum.centreon.com/archive/index.php/t-4506.html</a><br>
<br>which essentially says nagios.cfg:normal_check_interval and nrpe.cfg:step are tied together and if you change normal_check_internal you need need to lose all your data. The existing data isn't super critical. We're happy to lose it. I tried removing ./var/rrd directory (well rename) but then all the graphs broke with 'no such device' error. What other directories do I need to delete to clear all nagiosgrapher/rrdtool data?<br>
<br>Cheers <br>
